Maintaining a comfortable and energy-efficient environment is crucial for any building, whether it's an office, a hospital, or a manufacturing facility.

A Building Energy Management System (BeMS) is a vital tool that helps building owners and facility managers control and optimise their energy usage.

By constantly monitoring and adjusting heating, cooling, lighting, and ventilation systems, BeMS can significantly reduce energy consumption and costs, improve occupant comfort, and promote sustainability.

However, to ensure that a BeMS continues to function effectively, it's essential to perform regular maintenance and upgrades. And many people won’t be aware that this service is not included in your standard boiler service.

Which is where companies like Javelin Controls can help.

In this blog post, we will explore the importance of maintaining your Building Energy Management System and the benefits it can provide for your facility and how to go about getting it serviced.

BeMS Maintenance

Most sites will maintain their boilers regularly and probably have a maintenance agreement.

As mentioned above, this will cover maintenance of the boiler itself but not the systems that control it.

We wanted to stress this because some building owners may not realise that boiler maintenance does not include the BeMS system or that the BeMS system needs maintenance.

Why Is BeMS Maintenance Important?

A Building Energy Management System is a complex network of mechanical and electronic components that work together to control and optimise a building's energy usage.

However, like any system, a BeMS can experience malfunctions or failures that impact its performance and efficiency.

One common cause of BeMS issues is mechanical components that fail due to age or wear and tear. This can include sensors, valves, actuators, and other devices that regulate the heating, cooling, lighting, and ventilation systems.

Another factor that can cause problems is wiring, which can become damaged or disconnected over time, resulting in inaccurate readings or system failures.

Additionally, battery backup failure can be a cause of BeMS malfunctions. The backup battery is crucial for ensuring the system continues functioning during a power outage. If the battery fails, it can lead to unexpected shutdowns or data loss, affecting the system's overall performance.

Regular maintenance and monitoring of a BeMS can help identify these issues and prevent them from impacting the system's effectiveness and efficiency.

BeMS Maintenance: Key Processes

Regular BeMS maintenance involves various processes, including monitoring, testing, and calibrating the system's components, such as sensors, controllers, and communication networks.

It also involves updating the software and firmware, performing security checks and backups, and identifying and fixing any system faults or errors.

In addition, BeMS maintenance can include data analysis and reporting, which helps identify energy usage patterns and potential improvement areas.

Let’s examine some of the most important processes involved with BeMS maintenance.

System and Programming

Over time, changes in the building's occupancy, usage, or infrastructure can impact the system's programming and cause inefficiencies or malfunctions.

By regularly checking the system's programming, BeMS technicians can identify and address any issues, optimise system performance, and ensure that the system operates in accordance with the building's current requirements.

Moreover, verifying the accuracy and functionality of the system's programming can help prevent energy waste, improve occupant comfort, and reduce the risk of unexpected breakdowns or system failures.

For example, a power failure on site - or if the system is disconnected for any period - can cause issues if the backup battery has failed.

Sensors, thermostats

Checking sensors and thermostats is a crucial part of regular BeMS maintenance because they collect and transmit critical data about the building's environment to the system's controllers.

Faulty or poorly calibrated sensors and thermostats can lead to inaccurate readings, resulting in inefficient or ineffective operation of the BeMS.
This can cause increased energy usage, reduced occupant comfort, and even system failures.

Therefore, checking and calibrating sensors and thermostats as part of regular BeMS maintenance can help ensure that the system operates accurately and efficiently, reducing energy waste and costs while maximising occupant comfort.


In conclusion, maintaining your Building Energy Management System (BeMS) is essential for ensuring that your building remains energy-efficient, comfortable, and sustainable.

Regular BeMS maintenance involves monitoring, testing, and calibrating the system's components, updating the software and firmware, and analysing data to identify potential areas for improvement.

Building owners and facility managers can optimise the system's performance, reduce energy waste and costs, and extend its lifespan by conducting these tasks.

Moreover, BeMS maintenance can help prevent unexpected breakdowns or failures, minimising the risk of costly repairs and downtime.

If you want to ensure that your BeMS operates at peak performance, consider partnering with an experienced HVAC company that can provide expert maintenance and support services.

With proper care and attention, Javelin Controls can help ensure your BeMS will continue providing optimal energy management and occupant comfort for years.

A commercial HVAC system is an essential component of any commercial building, providing occupants comfort, air quality and safety.

Understanding how an HVAC system works is crucial to ensure optimal performance and longevity.

Whether you are a building owner, facility manager, or simply interested in learning more about commercial HVAC systems, this post will provide valuable insights and information to enhance your understanding.

What Is Commercial HVAC?

Commercial HVAC (Heating, Ventilation, and Air Conditioning) refers to the heating and cooling systems used in commercial buildings to regulate the indoor temperature and air quality.

There are various types (which we will explore in more detail), but these systems typically have several components, including an air handling unit, refrigeration cycle, ductwork, and controls.

How Does A Commercial HVAC System Work?

A commercial HVAC system uses various components to regulate the temperature, humidity, and air quality inside a commercial building.

The system consists of the following components:

Air Handling Unit:

This component provides heating and cooling by circulating air through a heat exchanger or evaporator coil.

Refrigeration Cycle:

This component cools and dehumidifies the air by using a refrigerant to transfer heat from the indoor air to the outdoor air.


Ductwork distributes the conditioned air throughout the building via a network of ducts.


These components regulate the operation of the HVAC system and control the temperature, humidity, and air quality. Commercial buildings benefit from more advanced controls for better energy efficiency and reliability. For example a central control system can use sensors to monitor and automate temperature schedules and even lighting operations. These control systems are essential for ensuring the overall system operates effectively and allows users to easily program the system to meet the exact needs of the building occupants.

Types of Commercial HVAC

There are several types of commercial HVAC systems, each with its own unique characteristics and benefits:

Split System

This type of HVAC system has two main components: an outdoor and an indoor unit. The outdoor unit contains the compressor and condenser, while the indoor unit contains the evaporator and air handling components.

Split systems are often connected to a building’s ductwork and are usually installed on smaller commercial buildings.

Packaged System

This HVAC system contains all the components in a single unit, either located on the roof or outside the building.

Chilled Water System

This type of HVAC system uses a central chiller to produce cooled water, which is then circulated to air handling units throughout the building to cool the air.

Variable Refrigerant Flow (VRF) System

This type of HVAC system uses refrigerant to provide heating and cooling, with the ability to vary the amount of refrigerant flowing to individual air handling units based on demand.

They are ductless and as a result a more expensive option.

Geothermal System (often referred to as ‘Heat Pumps’)

This HVAC system uses the earth's constant temperature to heat and cool a building, making it a highly energy-efficient option.

Each type of commercial HVAC system has its own strengths and weaknesses, and the best choice depends on the specific needs of a building.

It's essential to consult with an HVAC professional to determine the most suitable system for a particular building.

Benefits of Commercial HVAC

There are many benefits to having a commercial HVAC system.

Here are five ways we think they can help buildings and their occupants.

  1. Comfort: They provide a comfortable indoor environment for employees, customers, and visitors.
  2. Indoor air quality: They regulate the air quality by removing contaminants and controlling humidity levels, which helps to maintain good health and reduce the risk of respiratory problems.
  3. Energy efficiency: They use energy-efficient equipment to regulate temperature and reduce energy costs, ultimately leading to a reduced carbon footprint.
  4. Safety: They play a crucial role in fire safety by providing proper ventilation, controlling humidity levels, and removing harmful gases and fumes.
  5. Productivity: A comfortable indoor environment can improve the productivity and well-being of employees and customers, leading to increased satisfaction and profitability.

The need to reduce energy consumption has never been more pressing.

On top of the long-term push towards sustainability, we've seen a huge rise in energy costs due to the war in Ukraine.

So, we thought it was a timely opportunity to look at how best to improve commercial building energy efficiency.

How To Improve Energy Efficiency In Buildings

Surprisingly, although some energy-saving advice is available for homes, more needs to be said about commercial premises. Yet, there is an opportunity for many buildings to easily save 25% on fuel bills with minimum cost and disruption simply by following a simple 3-step formula:

  1. Maintenance
  2. Optimisation
  3. BeepBox

Let’s explore each step in more detail.

Step 1 – Maintenance

Gas boiler systems need regular maintenance to work at their optimum efficiency, and most sites have programs in place to ensure this happens.

However, only a few sites also regularly maintain their heating control system. The control system controls the boilers and directs the heating around the building. Without regular maintenance, sensors can become faulty, fail intermittently or fall out of spec, which causes the heating system to generate heat when not required, wasting energy.

Regular maintenance will pick up these issues (including any boiler cycling problems) and rectify them for minimal cost and with minimal disruption.

Step 2 – Optimisation

Optimisation means optimising the system to the needs of the building's users.

This is rarely done, usually because it's difficult and because of a lack of awareness of what systems can do.

Many control systems reside within the plant room of the building.

They were probably programmed when the system was installed and then never revisited. In the meantime, the needs of the building could have changed many times, and that original programming is no longer appropriate.

Part of the problem is that these systems were never designed to be easy to use. However, it is easy to upgrade a control system.

The overall heating system and boilers remain unchanged, and the system's efficiency improves.

Costs and downtime are minimised, but the return on investment can be significant.

Step 3 – BeepBox

The final step is to install an additional control system whose job is to optimise the running of the boiler.

The remarkable BeepBox system from Javelin can reduce gas consumption by up to 18%

What Is A BeepBox?

BeepBox is a unique product designed and built by our expert engineers to enable users to make significant savings on their energy consumption.

The system is designed to target inefficiencies inherent in the design of most heating control systems.

How Much Energy Can BeepBox Save?

BeepBox has been shown to reduce energy consumption by 17.6% in laboratory tests, a figure supported by real-world data from actual installations.

In addition, only a few buildings have their basic heating system correctly configured and optimised.

As part of the BeepBox installation and commissioning process, we will survey the whole system and make recommendations for further enhancements.

In practice, we’ve seen overall improvements of 25% or more. We’re confident BeepBox will save users money and have created a unique guarantee to make BeepBox a no-risk proposition.

How Does BeepBox Work?

The unique system is designed to target inefficiencies inherent in the design of most heating control systems.

Our BeepBox is a specialised control system that is installed alongside your existing system. It is non-invasive from a mechanical perspective and requires minimal downtime of the current system.

No additional plumbing or pipework is required. The installation comprises our BeepBox control system and some additional sensors to accurately measure the status and temperatures in your boiler system.

Using proprietary algorithms, we reduce boiler output at specific periods in the heating cycle to maintain heating output whilst reducing wasted energy.

In addition, during the commissioning process, we tailor BeepBox to your system's specific needs and characteristics to ensure optimum performance.

Because BeepBox work by targeting inefficiencies found in heating control systems, wasted energy can be reduced without having any impact on the heat output to the building.

Guaranteed Savings

We guarantee that you’ll save money with a BeepBox.

And we don't say that lightly.

If the system isn't saving you money during the first three months after installation, we will remove it - at no cost - and give you a full refund of all charges you've incurred.

How Much Does The BeepBox Cost?

We aim to keep costs down as much as possible for our clients.

That’s why we do not charge any installation, up-front or capital costs.

Instead, you rent the system from us by paying a monthly subscription.

These subscription charges will depend on the size of your building and the current boiler system.

There’s a calculator on our website where you can see how much you could save with BeepBox.

Post-pandemic life is beginning to return to normal – or perhaps a new normal. In many ways, the ‘working from home’ culture, which was enforced upon many of the working population, made us both grateful for the technology that facilitated its feasibility but also increased our demand for more significant improvements. Especially for those required to return to the office.

The expectations for commercial buildings to provide bespoke services to better our home office environment could not be greater. The office is truly competing with the home. And that is why ‘intelligent building systems’ are becoming an ever-more present landscape in our towns and cities.

But what are intelligent building systems? And what can Javelin Controls do to help us future-proof our HVAC infrastructure?

This blog will examine the benefits of intelligent building systems and how Javelin Controls can help expand your existing technology.

What Are Intelligent Buildings?

Let’s start by looking at the definition of intelligent buildings.

The term can describe various systems, all of which are designed to ensure better security and efficient climate control.

But if we were going to go with one overarching definition, the Chartered Institution of

Building Services Engineers (CIBSE) defines an intelligent building as: "one that provides a productive and cost-effective environment based on three basic elements: people, products, and processes”.

Modern, intelligent building design integrates Internet Of Things (IoT)-connected devices (such as cloud computing, augmented reality, and other systems) into a single platform.

So, for example, if an intelligent building knows that someone normally walks into a room at 10 am, it can adjust HVAC systems accordingly to ensure the temperature is at a comfortable level. It can also tell if the individual does not arrive, adapting the HVAC to save energy. Not only does this make the environment comfortable for that particular worker, but it also works to conserve energy and costs.

In terms of applications, there are countless possibilities for the technology.

The example used above is representative of the majority of designers’ desires to cater for the corporate world. But in commercial real estate spheres, smart apartments and intelligent buildings can complement each other by tapping into a facility-wide network and granting specific permissions to authorised tenants. The front door key could become a thing of the past.

Benefits Of Intelligent Building Technology

We’ve touched on some of the benefits of intelligent building technology already.

But why is the technology so important?

Let’s look at some of the most significant advantages in a little more detail.

Building efficiency

Intelligent buildings have sensors that can provide essential data about how the building is being used. So, for example, real-time adjustments can be made about the amount of heat and light required for specific areas.

These sensors can also help identify areas that are used consistently and those that aren't. This can allow managers to optimise space utilisation and therefore help facilitate growth.

Reduced energy consumption

And an essential by-product of a more efficient building is the impact this can have on energy consumption.

Smart technology could help save anywhere between 5% - 35%, which not only saves money but also help make the building more environmentally sustainable.

Predictive maintenance

When an IBMS runs a building, it can help identify future maintenance issues before they even arise.

Preventive maintenance, therefore, becomes a core function of facility upkeep. When you have a more insightful overview of how the building operates – and is used - it's far easier to implement maintenance at the right time.

Increased occupant satisfaction & productivity

Because intelligent buildings can offer improved lighting, air flow quality, thermal comfort and sanitation facilities, those working on-site get to benefit.

Businesses can benefit from an increased employee retention rate, and productivity can be seen to grow thanks to the more confirmable workspace.

What Is An Intelligent Building Management System?

Intelligent buildings are being designed and constructed in major towns and cities worldwide.

But what is it that actually makes them intelligent? And can that technology be introduced to existing ‘non-intelligent’ buildings?

Modern buildings are made up of a complex network of systems, all of which need to be controlled by a facilities manager. Traditionally, they include:

Of course, as structures continue to modernise, the number of systems that need to be managed continue to grow. An IBMS can grow with them, meaning - in theory - they can become 'future-proof'.

Traditionally, these settings have all been controlled separately. But an intelligent building management system can put them all into one place.

The Differences Between Intelligent Buildings And BEMS

Building Energy Management Systems (BeMS) refer to systems used to control and automate many of the functions associated with building management.

But it is the 'I' part of IBMS (which stands for intelligent) that represents a new level of complexity that traditional BeMS cannot achieve.

While a BeMS could turn on the lights and heat at a particular time in the morning, an IBMS could turn on the lights and heat when a specific person comes into the office and then adjust the brightness and temperature levels to that individual's preference.

How Javelin Controls Can Help

Javelin Controls has decades of experience supporting commercial clients across the South East with their HVAC needs.

Our expert team designs, installs, and maintains BeMS and IBMS systems, advising on their capabilities and what would best suit individual commercial sites.

We also know that requirements change. Future-proofing can be difficult, but we help ensure that our clients have the most options available to them when they upgrade their systems.

That’s why all the systems we install have intelligent building management built in. So, if a customer initially wants a system that controls their HVAC, we install systems that could potentially expand into a full smart-building control system later down the line.

Businesses of all sizes are optimising workplace heating or looking at ways to incorporate more energy-efficient and low-cost strategies. With rising energy tariffs and increased awareness of our environmental impact, it's time to look at all the possibilities.

There are several options available to businesses, many of which are championed by the Government. They include solar panels , heat pumps and other products that boost efficiency & directly impact your carbon footprint.

While these are desirable options with their own advantages, investing in a Building Energy Management System might be your best bet.

BeMS are becoming increasingly intelligent and can impact your finances and CO2 savings. They are also cheaper to install, less disruptive and will provide users with immediate benefits.

We've previously looked at the benefits of BeMS over traditional heating methods, but let’s take a look at the reason for these systems being the ideal starting point when it comes to optimising workplace heating.

Financial Benefits Of Energy Management Systems For Commercial Buildings

Lower Initial Costs

The initial purchase of a heat pump or the cost of buying and installing solar panels is often enough to make people think twice.

The promise of a long-term return on investment can be the selling point, and while this may be the case in the future, optimising workplace heating should ideally offer you an immediate benefit.

A quality Building Energy Management System will boost efficiency and reduce the need for manual intervention right away.

This means that not only could you be saving on the system's initial price by choosing a BeMS, but you are more likely to notice quick results and lower bills.

Maximise Return On Your Existing Systems

As well as cutting installation costs, many businesses are looking for quick-fix solutions without understanding which areas of their systems need repairing. This can result in companies replacing systems that are still in working order.

Those who don’t understand the possibility of a quick repair or perhaps don’t have time to research professionals like Javelin Controls may assume replacements are the only option. Less qualified companies may also push them to replace entire systems if they think there is money to be made.

That's why a thorough understanding and information from resources such as our blogs can be invaluable.

Instead of switching to solar panels or heat pumps while your current equipment is still in good condition, utilise the function of a BeMS to maximise your return.

Linking your systems to a control panel will ensure they are being optimised and utilised to their full potential. Energy costs can be reduced because a BeMS can more precisely match heating output to the exact needs of the building vs. just turning the heating on using a program timer that was probably programmed years ago and forgotten about.

Maximising The Efficiency Of Energy Management Systems For Commercial Buildings

So, a BeMS could save you money both in the short and long term.

But as well as financial incentives, reducing overall energy consumption can also positively impact the environment.

Whether you’re looking to invest in a BeMS from Javelin Controls - or already have one installed - every step must be taken to achieve full optimisation and utilise all of its capabilities.

Correct Programming

Once installed, Building Energy Management Systems must be programmed correctly for your premises.

For example, managing each area and component can be a struggle if you have a large site.

But programming a heating system via a nice UI is far easier than trying to use a program timer or the front panel of an older control system in the plant room.

Each room in your property will need heating at different times and in different amounts. This will depend on a few factors:

Ensuring every precaution and every factor is considered whilst programming your system will optimise its performance.

That’s why we always recommend communicating your priorities in terms of efficiency and function during the initial consultation.

Specialising in BeMS controls, our team is well equipped to optimise workplace heating and cooling and can link every aspect of your building together in one holistic group.

Complement Your BeMS With Intelligent Sensors

Sensors are a great way to get the most out of your systems.

They can carry a vast array of highly targeted and accurate data.

Sensors can help increase the capacity of your BeMS and its capabilities to match the needs of your business more closely.

The sensors may be linked to:

These sensors can be tailored for your building’s particular configuration and will minimise the risk of incorrect adjustments.

However, it is vital to check that they are operating correctly and measuring the correct levels accurately. Service engineers will be able to run checks as they monitor your BeMS, and you can add sensors when you feel it is needed.

This allows you to keep up with any growth and expansion that may happen over the years. Your BeMS will be able to keep up with demand and prolong the life of your current systems without reinvesting in simple, single-function products like solar panels.

Optimise Workplace Heating With Javelin Controls

If you’d like to learn more about building management systems or other HVAC controls, head over to our website or have a read of some of the blogs we’ve written in the past.

Before jumping into the more fashionable solutions, a BEMS should be your first port of call. It can save you money on the initial purchase, and you'll be much more likely to benefit from immediate results.

If you’re looking for a long-term solution that will maximise the potential of your current set-up, get in touch with the team on 023 9400 4123 or email sales@javelincontrols.co.uk.

We can help you to transform your environment with a high-quality building management system. We’ll be more than happy to discuss your requirements and find a customised solution to suit your needs.

Now more than ever, businesses are looking for ways to save money and cut costs on bills, budgets and general maintenance costs.

The UK – and much of the rest of the world – is currently facing a cost-of-living crisis, with energy bills soaring.

As a result, you will want to keep an eye on the amount of energy your commercial heating systems are wasting.

Often it can be tempting to opt for the cheapest control system to save costs.

While this may save you a few pennies initially, these systems could prove more expensive long term. The cheaper products don't have the same capabilities as top-of-the-range commercial heating systems.

As a result, businesses are losing out on energy savings and efficiency within their property.

Investing in a quality building energy management system (BEMS) can make all the difference.

What Is A Building Energy Management System?

We’ve previously written about building management systems here at Javelin Controls (the benefits of a BMS and 5 key features of a BMS).


The terms BMS and BEMS are often used interchangeably, but there are key differences.

The most notable difference is that a BEMS manages energy-related systems. In contrast, a BMS monitors and controls a broader range of building systems such as fire alarms, CCTV, and motion sensors.

When it comes to energy efficiency, they are an essential part of any property’s strategy.

As a computer-based system, they can monitor and control various equipment simultaneously. They omit the need for human intervention and reduce the risk of things running when they shouldn't.

You can automatically control power points in your building and monitor them constantly - increasing and reducing output depending on their requirements. This will stop the need for constant heating, cooling or other energy-wasting activities.

Furthermore, having heating systems linked to your BEMS means it will represent around 40% of the building's energy usage.

With this in mind, investing in a quality control system could see you making the most of this energy and ensuring it is being used in ways that will benefit costs and reduce waste.

Why Are Traditional Heating Control Systems Wasting Energy?

The average commercial building wastes about 30% of its energy produced.

This could be for several reasons:

That last point is quite important: you rely on staff to keep the room at a comfortable temperature - hoping that the thermostat is controlled accurately and not tampered with.

BEMS chart

Your employees will all be most comfortable in different environments, and finding that happy medium can be near impossible.

Instead of resorting to arguments and blankets, a quality BEMS can ensure your building runs as efficiently as possible and caters to the majority.

How Does A Building Energy Management System Save Energy?

There are many ways that a BEMS can help your business save energy.

A quality system can control as much as 84% of your building's energy consumption.

By doing so, you could be saving money and significantly contributing to the improvement of your carbon footprint.

Let’s look at some energy-saving benefits of Building Energy Management Systems over traditional heating control systems.


By monitoring usage and demand, a BEMS can implement strategies to ensure you use less energy during peak times - prioritising the equipment and areas that need it most.

This capability also helps you better understand how and where you use most of your energy.

With a clearer understanding of energy usage, you can better predict how you will need to use certain systems in the future. As a result, you have more time to respond to issues and adjust your usage as it happens.

Weather Compensation

This function relies on a signal being received from the Building Energy Management System.

Room temperature data will be interpreted, and a control valve will help deliver the necessary output.

This ensures that only an optimal amount of energy is used while keeping the room at a constant temperature.

So instead of delivering constant heat at all times, it will recognise what is proportional to the external temperature and modulate the output to keep internal environments comfortable.

This reduces the need for the simpler on-off control you'd associate with general radiators and fan heaters, which can result in overheating a room and wasting energy by opening windows and doors.

Advantages of modulating control include:

Optimised Start/Stop

Optimised start/stop means the system 'learns' how long a room takes to warm up and cool down.

This allows room temperatures to be programmed differently. Instead of 'turn heating on at 6 am and heat to 20 degrees', the system is programmed to 'ensure the room is at 20 degrees by 8 am', for example.

Likewise, instead of 'turn off heating at 6 pm', you program it to ensure it’s at 20 degrees until 6 pm.

In each case, the system uses its knowledge of heating and cooling times to turn the heating on and off. This saves both money and energy as the system is used optimally.

In addition, by adding external sensors, the system can adjust its heating and cooling times accordingly (weather compensation)

Zone Control

Area or 'Zone' control is where the temperature of a specific area or zone can be controlled rather than the entire building.

You may, for example, need to keep a server room at a lower temperature than the surrounding offices.

Occupancy sensing can also help detect the presence of people and control the heating appropriately. This only works if you also have area or zone control so you can turn the heating on where those people are.

This means unoccupied rooms will not be heated – ensuring no energy is wasted.

Conversely, an area that is heavily occupied may need the majority of energy produced in the building.

To prioritise this, other systems can be linked together, making it simple for this computer-based function to recognise which rooms need heating.


There are many advantages that Building Energy Management Systems have over commercial heating systems, including:

They can cost more to install but ultimately save you money (and energy) in the long run.

By relying on the full, intelligent automation of the system, you can be assured that the optimum amount of energy will be used in your building all year round. In addition to saving you money, your staff will also thank you.

Can a heat pump replace gas boilers? That's the question many commercial and residential clients ask as the search for viable, alternative energy resources continues. The embers of the ongoing debate have been stoked by the government announcing it favours air source and ground source heat pumps as the eventual successors to boiler gas as part of its boiler upgrade scheme.

This blog aims to show the realities of heat pumps, how they compare to gas boilers and whether they will indeed replace gas boilers in the future.

We will explore how the two systems operate, their efficiency, eco-friendliness, and how much they cost to run and install.

Heat Pumps v Gas Boilers - Main Differences

Let's start the comparison by looking at how heat pumps and gas boilers work.

Firstly, boilers can heat cold water reasonably quickly, which is one of the main reasons they have proved so popular. They can heat radiators and, therefore, large open spaces - like offices or warehouses - to high temperatures in no time.

A boiler system is often designed to run at flow temperatures of around 70°C (this is the temperature of water sent round to your radiators). The water returns to the boiler after travelling around your radiators (called 'the return'), usually between 10-20°C cooler.

By contrast, heat pumps produce heat more slowly and at lower temperatures.

They ideally want to have an average temperature of roughly 37.5°C and a temperature difference of only 5°C. To be as effective, the radiators they feed in to need to have a much larger surface area. So rather than pumping water into traditional wall-mounted fixtures, they are probably best suited for underfloor heating systems.

When asking yourself whether to swap a gas boiler for a heat pump, you will need to be aware that existing radiators and pipework, as well as your existing source, may need to be updated.

Heat Pumps vs Gas Boilers - Efficiency

Which is more efficient: a gas boiler or a heat pump?

Natural gas boilers have a heat exchanger within the gas combustion chamber. Water passes through this exchanger and absorbs heat from the burning gas. Because it is so efficient, around 90% of the energy is absorbed into the water.

Furthermore, because much heat is created, water vapour condenses - hence the system being referred to as a condensing boiler.

The efficiency of a heat pump is known as the Coefficient of Performance (CoP). This is the ratio of the amount of electricity used to the amount of heat produced for the home.

For example, if the heat pump uses 1kWH of electricity and produces 3 kWh of heat, the CoP is 3 (or 300%) efficiency.

A wide range of contributing factors and many formulae are used to deliver and calculate this efficiency. So it is essential to understand precisely what you should expect from each system when comparing.

Heat Pumps vs Gas Boilers - Costs

A pound coin on a white background

This is ultimately what it boils down to: how much do either of the heating systems cost to set up and run?

Heat pumps are certainly more expensive to buy.

Currently, if you are looking at installing an air source heat pump, you can expect to pay between £8000 and £16000. It can even be as much as £28,000 if you need to upgrade radiators and replace pipework.

For ground source heat pumps, you are looking at around £14,000 to £25,000 for an installation and perhaps even more if you need a large borehole collector.

There are many variations of a boiler, with prices ranging from £500 to £2,500 depending on your chosen make and model. The installation will usually cost more.

But what about running costs?

As previously discussed, heat pumps run on electricity, and boilers burn gas. As a result, a cost comparison will need to consider the unit cost of each fuel.

Electricity costs between 12p and 24p per kWh, depending on your tariff. Alternatively, natural gas is between 3 and 5p.

This means that, in terms of financial cost, the heat pump would need a CoP between 3 and 5 (an efficiency of between 300 and 500%) to be comparable.

As the cost of gas and electricity changes, so will this calculation. However, there is one thing you can be sure of. The cost of energy will continue to rise, and the gap between the price between electricity and gas will close.

In the current climate, switching gas to heat pumps can be pretty expensive. Still, as the energy cost gap closes, the numbers will eventually become more favourable for heat pumps.

The fact that heat pumps save you money on energy bills and last twice as long as a commercial boiler means that over time, they will benefit you financially.

Heat Pumps vs Gas Boilers – Space Required

In order to further explain the realities of heat pumps vs boilers, we should also consider the amount of space both of them require.

Firstly, many of us will already be familiar with the size of a standard gas boiler.

However, heat pumps require alternative equipment for office set-ups.

There are two main types of heat pumps:

- air source

- ground source.

Air source heat pumps collect heat from ambient air whilst ground pumps receive heat from the ground.

Air source heat pumps usually have a large box measuring 1200mm by 1000m outside your building with a fan and compressor inside. This box absorbs heat from the air as the fan draws it through. Additionally, the outside unit needs 2 metres of space in front of it.

To install these, you will also need space inside the property for a hot water cylinder, control box and potentially a second buffer tank, which is about a third of the size of a standard tall hot water cylinder.

Ground source heat pumps, on the other hand, can be installed virtually anywhere. Open-loop systems will need access to a water source - but closed-loop systems do not, making them the more popular choice for urban companies.

The maximum length of the pipe will be 400m depending on the heat pump size you require. This means that, in total, the average system will need between 600 and 1200 square metres of land that is clear of trees and buildings.

Final Thoughts - Will Heat Pumps Replace Gas Boilers?

Although heat pumps are very sustainable and much more efficient than the standard gas boiler, they have some glaring limitations in the real world that don't always make them a suitable, direct replacement for gas boilers.

Firstly, they can be very costly to install compared to gas boilers.

Additionally, they are not yet suitable for every property. Suppose your business is poorly insulated and you have a limited budget. In that case, improving your insulation will be a far more cost-effective way of limiting your energy use (and therefore lowering your monthly bills).

Something else worth considering is that to replace your boiler with a heat pump, the radiators will likely need to be replaced.

And from our experience, we have found that many gas boiler installations are not set up optimally. Each unit can be programmed to better reflect the use of the building and could ultimately save you money on your bills. If in doubt, we can always check the basic installation is correct for you.

For these reasons and more, heat pumps may not yet be a viable alternative to gas boilers for everyone. However, as the energy cost gap closes, the numbers may eventually become more favourable toward heat pumps.

Hybrid systems - making use of both a heat pump and commercial boiler – are also becoming available. The advantage here is that the heat pump takes some of the strain - allowing the boiler to run for longer and reducing energy costs.

If you're unsure which to opt for or are wondering if switching to one rather than the other will benefit you, hybrid systems may be the way to go.

Sadly, one of the news stories that you can’t escape from is the growing climate change crisis. As a result, many businesses and homeowners are taking significant steps towards sustainability and achieving ‘net zero’ status. Businesses, in particular, are adapting to climate change by looking at renewable energy sources, such as solar power.

If that's something you're interested in, this blog will help answer any questions about the benefits of solar power for your business.

How Does Solar Power Work?

Solar power is the conversion of renewable energy from sunlight into electricity.

Many different technologies are available now to businesses to help harness that power.

Two of the most popular are:

We'll look at each of these in turn, analysing their benefits to see which could better suit your business.

Solar Thermal Energy

Solar Thermal Energy (STE) is used to heat water, which can be used for commercial and residential buildings.

Panels can be installed on rooftops - or other surfaces open to the elements - to absorb the sunlight.

These panels house tube-shaped collectors which are filled with water. As the liquid heats up, it is pumped into a specially designed hot water cylinder, where it is stored until you need it.

Benefits of Solar Thermal Energy for Businesses

Solar thermal energy technology has a wide range of benefits for businesses.

It does not take up as much space on roofs as Solar PV Energy panels (more on that later) and can therefore keep offices looking more ‘aesthetically pleasing’.

Thermal energy is also 70% more efficient at collecting heat from the sun's rays than solar PV. It is also a lot less complex to run and maintain.

Therefore, it is a more affordable form of solar power in terms of economics.

Disadvantages of Solar Thermal Energy

While there are many advantages to this technology, there are some disadvantages, particularly for businesses based in the UK.

For example, it is less effective in the winter months when the sunlight is often weaker and the weather is cloudier.

The panels also have a shorter life expectancy than Solar PV. Many other competitors can expect to outlast solar thermal technology by around ten years.

A Good Solution For Businesses?

Thermal solar technology is a superior energy solution compared to alternative forms of green energy like tidal and biomass energy.

However, its exclusive function for water heating can be a downfall when you need solutions for the entire building's power.

And – as alluded to above – the technology is perhaps best suited for warmer climates because the ability of the panels to absorb the sun's rays in winter months diminishes. Relying on sunlight during the summer to heat your water can be risky, particularly with the UK’s more temperate weather.

Solar PV Energy

Solar PV is a much newer technology than solar thermal technology.

To the untrained eye, they look similar to Solar Thermal panels. They are also placed on roofs, but – as we will see – there are some significant differences between the two technologies.

There are three common types of PV panels that are available:

Monocrystalline is the most efficient of these options but is also the most expensive. Alternatively, polycrystalline is a little less efficient but comes at a slightly cheaper price range. Lastly, thin-film solar cells are the most affordable option but are also the most flexible.

Deciding which is best for your businesses will depend mostly on your price range.

How Do These Work?

Solar PV energy works by absorbing sunlight and then converting it into electricity using silicon-based technology.

Advantages of Solar PV Panels

Solar PV Panels have a range of advantages for businesses. For example, they provide you with clean and green energy that can be the best first step towards carbon-neutral offices. They can also do this for a long time of up to 50 years which will see you benefiting financially in the long run.

Furthermore, they are considerably efficient during the summer months yet won't freeze during the winter. Even when there's the slightest bit of brightness during the day - the panels will absorb the rays and allow you to make use of whatever sunshine you have.

In addition, they can cover the energy requirements of appliances that have a high-energy consumption. This includes the refrigerator, washing machine, dryer and much more.

Lastly, the government scheme of a feed-in tariff means that solar PV will take less time to pay for itself than other green energy sources.

This programme is designed to promote renewable and low-carbon technology - giving you an incentive to implement it in your business. You will benefit from quarterly payments for the electricity your installation has generated. This is determined by readings you submit to your energy supplier.

Disadvantages of Solar PV

Whilst solar PV is a remarkable piece of technology in its longevity and efficiency, it does have some drawbacks for those on a budget.

The initial costs are often quite expensive for some businesses.

However, the return you will get can see significant benefits for your business. So it is undoubtedly worth the investment if you can.

And it is worth noting that the panels take up a lot more room than the Thermal Energy equivalent. So available space is something business owners would need to consider.

A Good Solution For Businesses?

Solar PV can be a great sustainable solution for your energy needs.

It allows you to benefit from a phenomenal form of green energy that is hard to beat. Additionally, solar PV will also allow you to earn money from the Feed-in Tariff.

Overall Benefits of Solar Power Systems for Businesses

Now that we have explained both forms of solar power systems let's explore how the overall concept of solar energy can benefit businesses.

An office building with solar panels

A Truly Renewable Source of Energy

Firstly, one benefit for businesses is that solar power is one of the only truly renewable energy sources.

In much the same way that wind turbines rely on gusts, the sun’s presence is paramount for this technology. Fortunately, scientists currently predict that we have another five billion years of energy left to use from it.

As long as your business gets a few hours of sunlight a day, you can benefit from this energy source.

A Reduction In Energy Bills

You rely less on the national grid and traditional utility suppliers to power your business by generating your own energy on-site.

The more energy you produce, the more you will save when using these energy sources.

How much you save will depend on the size of your system and what your typical usage levels are.

That being said, these appliances can easily save you hundreds or even thousands of pounds each year.

Low Maintenance Costs

An additional aspect of solar energy that makes them ideal for businesses is the low maintenance costs involved in keeping them.

Generally, you will get away with cleaning them a couple of times a year. As they do not have any moving parts, you do not need to worry about wear and tear, providing a need for additional maintenance.

So once the initial cost has been paid, you can expect minimal spending needed for maintenance and ongoing repair work.

Reducing Your Environmental Impact

Green initiatives are becoming increasingly more critical within our global agenda.

Customers and consumers expect many businesses to be as responsible as they can when it comes to the environment.

As solar panels produce energy without greenhouse gases or water pollution, they are a viable solution in the world's quest to become more sustainable.

Additionally, solar panels do not produce noise pollution - making them perfect for dense urban areas.

Space Efficient

A somewhat smaller benefit of solar power sources is that they are both silent and space-efficient.

For businesses that are expanding physically, such as with new premises or on-site buildings, the fact that these can be installed simply on the roof of existing buildings can save a lot of needed space elsewhere.

This means that you won't need to find home turbines or large water heaters storage.

Final Thoughts On Solar Power For Businesses

Many businesses are starting to see why investing in renewable energy is so important.

It shows that your brand cares about sustainability and the planet's future, which helps your brand reputation and the global environment.

We have looked at the two main types of panels. While both are relatively cheap to install, space-efficient (compared to traditional energy sources) and silent, they have differences that businesses would need to consider.

Plenty of building improvements are becoming part of new hybrid technology schemes where we pair current systems with state of the art, sustainable solutions. The idea is to move towards a more cost-effective and energy-efficient product. Standard boilers can get expensive quickly over the winter. However, you could save money with a hybrid heating system and see other benefits such as reducing your carbon footprint.

This modern way of warming your business provides a combination of heat pumps that offer plenty of advantages along with conventional systems like gas boilers. Together, you have a system that becomes far more cost-effective and eco friendly. But there are plenty of other reasons for this approach becoming more popular. We have put together this list of ways we can help you save money with a hybrid heating system and what other benefits are in store for you.

1. Energy Saving

On its own, a boiler has to use a lot of energy to produce the same amount of output as a heat pump. Because of this, traditional boilers never reach 100% efficiency, meaning you will be using more energy to power the system than you’re getting back as heat!

Heat pumps are excellent at generating heat while using a small amount of energy. In fact, the numbers can be astonishing - transferring up to 3 times as much energy as they need to run. This just goes to show how much you could be saving on your electricity bill to achieve the same output by making even partial use of a hybrid heating system.

The idea of using both in tandem means that heat pumps will be active for the majority of the time you need them. But as traditional gas boilers perform better in plummeting temperatures - the system will kick in to top up your business over particularly cold days or evenings.

The advantage here is that you are not losing the power associated with a boiler, but you can benefit from the energy efficiency of a heat pump. This ensures your building is prioritising the cost-efficient method, but making use of each when it is most suitable.

2. Lower Heating Bills

While a heat pump uses some electricity to run, it does not need extra fuel in the form of gas or oil to produce its output. While you pay a supplier to run a traditional boiler - pumps will run on free energy from the air around and a minimal amount of electricity.

The heat pump will carry out a pre-heat process and the boiler will then raise the temperature to that required. This means that they are both operating at the same time. However, with heat being produced from the boiler element less often, you won’t be paying as much for gas.

Since the temperature of the water entering the boiler has been pre-heated, the boiler has to use less energy to heat it to the required temperature. When you manage to reduce the running costs and other fees associated with boilers, you could be looking at some significant savings!

As energy and fuel prices have risen so rapidly in recent months, now seems like a better time than ever to invest in this modern technology. People are trying to save money wherever they can, so don’t take a hit from out of date appliances. Contact Javelin today to learn more.

3. Save On Insulation

In order to benefit from and make the most of the heat output when using a heat pump on its own, commercial buildings will have to be highly insulated and properly maintained. This allows heat to remain inside without losing the precious output and having to run the system for extended periods to maintain a constant temperature.

As a result, it can cost thousands to ensure each roof, wall and window is properly fitted and insulated to trap the most heat possible throughout the winter and remain cool in the summer. But you can save money with a hybrid heating system as the heat pumps can generate so much output and will be paired with the boiler’s output for extra heat.

You can run them for longer periods of time, without even having to worry about the same level of expense as heating from a boiler. So not only will you be saving on fuel, using greener energy and lowering your carbon footprint, but you won’t have to fork out for extreme standards of insulation. It is a much more reliable method that we can help you install.

4. Long-Lasting

You’d be lucky to get more than around 10 years out of your standard boiler and maybe less if you’re using it to heat large premises. This is simply because it uses a lot of power to draw energy from the fuel and pump it into the building or to heat water. However, when you invest in a hybrid approach, you can be sure that the boiler function will only be used when necessary.

This means, you are not relying on it as much to act as the main heating element and so it will inevitably last far longer. When a new boiler system can cost upwards of £10,000, you want that money to be put to use for as long as possible.

Not only that but working in collaboration with a heat pump will mean that despite the upkeep of a regular maintenance schedule, the cost of this should be lower. This will save costs on call out charges, labour fees and part replacement. As well as general running costs reducing, the unlikely need for constant checks and replacements will see significant savings in the long run.

5. Renewable Energy Source

Solar Panels in a green field

Oil and gas boilers are known for heavily polluting the atmosphere with carbon dioxide. The use of fossil fuels, while still necessary in some cases, is being reduced greatly as technology advances and we make the move towards a net-zero approach.

Renewable energy sources such as heat pumps, solar power and wind turbines are excellent alternatives that offer cleaner output and can contribute to the reduction of your carbon footprint. While fully electric sources will take priority, hybrid heating systems move us in the right direction towards a fully renewable product.

However, as they supply us with renewable energy – they also help us to overcome the limitations of an individual heat pump. This includes a low-temperature output whereby they become less effective in the varying and plummeting temperatures we’re so familiar with, in the UK. So by utilising both sides, we are positively contributing to the environment and ensuring we warm our businesses in the best, most efficient way possible.

Save Money With A Hybrid Heating System: Even More Benefits

Not only can this method ensure you cut costs on energy bills and fees associated with maintenance, repair or replacement – but it can ensure you are living the most environmentally friendly and convenient life possible.

Technology Integration

These days, your office can be warm before you even walk through the door. You no longer need to arrive at work and suffer from a cold office, because the advancement in technology and our state of the art controls means you can monitor and change the status of your heaters from anywhere.

Cooling AND Heating

Another great advantage of a heat pump is that it can work in reverse. This means that instead of paying even more for a top of the range air conditioning unit - your heat pump element of a hybrid system can remove the heat for you. It works in a similar way but will still offer the benefits of energy efficiency and a renewable output.

As we know, the UK seasons can be hit and miss with temperatures varying up to 20 degrees in a single day some months. The advantage of this function is knowing you have the ability to efficiently heat your building and then cool it with the same device when needed. This eliminates the need for more expensive equipment that will inevitably need cleaning, maintenance and will take up space in your building.

Let’s Discuss Your Heating And Control Needs

In conclusion, there are plenty of ways to save money with a hybrid heating system and even more benefits to go with it.

We should all be making a conscious effort to reduce our carbon footprint and invest in cleaner means of heating or cooling our offices. These products offer this amazing advantage while tackling the limitations a heat pump may provide on its own.

Not only that, but they can help save on external costs associated with traditional boilers and the need to control these processes more easily. So if you want more advice on how we can help integrate these new technologies into your commercial building, don’t wait to get in touch.

A fully automated system will give you the freedom and reassurance you need. For more information about building management or HVAC systems, you can ring us, or email sales@javelincontrols.co.uk.

Gas and CO2 detection is commonly used as part of a building’s health and safety structure. Both fixed and portable detectors can be used to protect the occupants of any property from potentially hazardous environments. They can be used to avoid critical situations that wouldn’t have otherwise been realised due to the often odourless and invisible risks.

Fixed gas and CO2 detection will be integrated with a central alarm panel. Their sensitive and reactive nature means that people can be warned of potentially dangerous leaks or issues before they pose too much of a health and safety risk. Without these systems in place, it can prevent buildings from passing inspections and could lead to critical levels of these harmful gases as we saw first hand on a site previously.

Once we had installed these new systems - the extent of the risk displayed was shocking. If it weren’t for our recommendation, the site may never have realised how harmful the levels were and could have had to deal with some of the consequences such as the ones we will discuss below.

Risks Posed By Improper Gas And CO2 Detection

Around the clock, measurements are vital for ensuring every area in a building maintains safe and minimised levels of pollutants, toxins and harmful substances. You will incur less risk by installing the correct devices into your office space.

These hazards are particularly apparent in buildings that house boiler rooms. This is because the confined space can quickly fill with harmful gases, but access will still be required semi-regularly for maintenance and repairs. Known as the ‘silent killer’ - carbon monoxide can leak from pipes and cracks in faulty boilers - spilling out into the rest of the building, almost undetectable without an alarm.

However, wherever possible and even in the absence of a boiler room, Javelin will install products in positions to alert occupants in the event of a critical situation or sudden change in the environment.

Oxygen Depletion

When a room’s atmosphere gets overloaded with pollutants, it can get to a point where the ambient air now makes up the minority of what people are breathing in. This means that there is a reduced level of oxygen, making it unsafe for people to enter without proper apparatus.

The challenge here is identifying where a lack of oxygen is apparent. Usually odourless and colourless, the harmful gases remain undetectable. But when you have the proper detectors installed - they will pick up on even the slightest changes in the atmosphere and alert those both inside and outside of the designated area.


In rare cases and usually in specialised warehouses or laboratories - a build up of certain gases (such as methane) to substantial levels can leave a risk of explosion. When under pressure or in the presence of heat and flame, combustion can cause extremely serious damage to occupants and the property.

Where this may be a risk, infra-red or catalytic sensors are usually installed to monitor levels of potentially explosive gases. The advantage here is that they can be set to different sensitivities for pollutants that may be safe in small quantities and even expected to be found in certain areas.

Usually, to ensure the most efficient resolution of any leaks or issues - sensors are set to alert when just 10% of the amount of gas necessary to cause an explosion is detected. This makes it possible to initiate extraction and ventilation of all the areas affected and mitigate the risk before it is too late.


Unfortunately, there are a number of toxic gases that pose health risks when inhaled in certain quantities. However, the ones we are most likely to be exposed to in general life or at work are carbon dioxide (CO2) and carbon monoxide (CO).

As we mentioned above, the ‘silent killer’ known as carbon monoxide can be of a great risk where boilers are concerned. When fossil fuels are not burned in their entirety, they produce carbon monoxide as a product. This means that using gas, oil or coal to heat our properties poses a risk to our health as well as the environment.

Gas Detection

When the gases leak into the atmosphere, they can slowly build up without being detected and cause ill health such as dizziness, headaches, unconsciousness and even more. This is why landlords are required by law to provide carbon monoxide detectors where fossil fuels are used as a source. The same applies to offices or other commercial buildings.

The importance of proper gas and CO2 detection is obvious here and while the government is enforcing these measures - it is also important we install products of the correct standard and carry out regular checks and maintenance.

Monitoring Classrooms

In education, it is highly recommended for classrooms that back onto the boiler room to have detectors for reasons discussed earlier in this article. However, any room can benefit and so it is a good idea to implement the safety feature across schools. With so many people residing in fairly small rooms in close proximity, it will not take much for the levels of carbon dioxide to rise.

Without proper ventilation, and relying solely on open windows and fresh air - it can be difficult to keep these levels within a normal range (especially in colder seasons). It becomes hard to notice when something needs to be done and so having a system in place to monitor this will ensure ventilation is increased when necessary and other precautions can be taken in the event of a leak.

Fixed Gas And CO2 Detection

As well as monitoring an environment, fixed systems offer the advantage of being able to take full control over your safety protocol. The main control panel can not only sound alarms throughout the building but can activate emergency outputs such as extraction and ventilation. This is often found in laboratories that rely on the timely removal of harmful substances but can be programmed in other properties too.

They can even link with your main management system to ensure areas are fully secured or that other processes are terminated to allow for repairs and access where it may otherwise be dangerous. As a result, the automation allows for fast reaction times and the safety of those involved. It mitigates the need for manual intervention as far as possible and monitors the environment consistently.

Energy Efficiency

Furthermore, installing these sensors in various areas of a building can reduce running costs in the long run. Being able to monitor levels of gas in the atmosphere reliably will reduce the need for constant ventilation or extraction. This means that factories, offices and other spaces may not need to run fans or conditioners as often as they currently do.

When they can determine levels are rising slightly too high - the control panel can initiate ventilation or other methods. But when this has balanced out and the room returns to safe levels, they can cut off and ensure the building is running as efficiently as possible. When we run systems like this non-stop, it can help to ensure we keep occupants safe but it may also be unnecessary and costly.

In Conclusion

The practice of proper gas and CO2 detection is something we may not prioritise in our regular health and safety systems. However, they can become integrated and sit as an integral part of daily monitoring. For many buildings, certain parts of this system are also a requirement. Without them, you could risk failing inspections or receiving fines.

Especially where fossil fuels and restricted areas are concerned, it is important we have a professional means of measuring these invisible risks. Not only can the team at Javelin ensure you are getting the right systems, but we can also install them to suit your needs and offer advice on how to integrate them with other building management systems.
