Ground Source Heat Pumps use ground loops to transfer energy from the ground into the refrigerant cycle. This Energy runs through a compressor, which in condenses and raises the temperature. This energy can then be transferred to your building to heat the internal space and for hot water.


There is no better time to consider going green to heat your home. Ground source heat pumps and other renewable heating solutions have become very effective and reliable. The benefits of ground source heating are:


Generates less CO2 emissions


Designed to work in cold temperatures


Can use Electrical power from other renewable sources, e.g. Wind.


Highly efficient, typically converting 1kW of electrical power to 4-5kW heat


Cheaper to run than Oil or LPG alternatives


Ideal to use with underfloor heating

What is a Ground Source Heat Pump?

Ground source heat pumps extract thermal energy from the ground near your property and converts this into heating & Hot water for your home. Ground source heat pumps work better in cold temperatures than Air Source, as they take heat from at least 1m below ground where there is a stable temperature throughout the year, which is ideal for homes in the UK.

How does a Ground Source Heat Pump work?

Pipe is laid in the ground in close proximity to your home (such as in the garden or paddock). Pipes can be laid either horizontally in trenches when adequate land is available or vertically in bore holes when space is limited.

A fluid called Thermal Transfer Fluid (TTF) flows around a loop of pipe and heat from the ground is absorbed into the fluid.

This fluid then passes through a compressor in the heat pump, which condenses the heat and is used in the home. This fluid is then sent back into the ground at a very low temperature to collect more heat again before returning to the heat pump.

Are Ground Source Heat Pumps geothermal?

A common misconception is that Ground Source Heat Pumps rely on geothermal energy as a heating source, i.e.the Energy from the earth’s core. In fact, Ground Source Heat Pumps in domestic applications utilise solar energy which has been absorbed by the earth throughout the year. This Solar Energy is effectively stored in the ground. As the earth is a good insulator the temperature below about 1m remains almost constant throughout the year.

At this depth the temperature of the ground remains around 10 degrees Celsius consistently, even if there is a large drop in air temperature above ground. For this reason, Ground Source Heat Pumps utilise a reliable source of stored energy that is free and present in most parts of the world, and gets replenished by the sun’s energy when it is removed.

Will it save money on energy bills?

A Ground Source Heat Pump installation is an effective and reliable way to save money on your energy bills, as they produce far more energy than they consume.

The process of ground source heating uses electricity to run the pump, however, the amount of energy collected from the ground to heat your home is significantly more than the amount of electricity required to power the system.

Generally, for every 1 kilowatt of electricity used by the pump, around 3-5 kilowatts of energy is extracted from the ground and transferred into your home. It is this level of efficiency that means a Ground Source Heat Pump will reduce the cost of your bills over traditional or outdated heating systems.


Ground Source Heat Pumps can be integrated into existing heating systems.

Heat pumps can work with existing radiators

Ground Source Heat Pumps can be installed on to an existing heating system, although some radiators may need to be replaced with a larger model to accommodate for the lower running temperatures of these heat pumps. Furthermore, we recommend aluminium radiators for use with heat pumps. Aluminium is an effective conductor and heats up very quickly. Therefore, transmitting heat into the room much more rapidly than steel or cast iron radiators.

Great with underfloor heating

Due to the low running temperatures of Heat Pumps they are very effective with underfloor heating systems, that are already designed to operate at these lower temperatures. Often our clients look at upgrading to the comfort of underfloor heating in their properties as part of this change. Our sister company Heated Floors specialise in upgrading homes to underfloor heating and can offer surprisingly simple retrofit options. For more information visit us at Heated Floors.


Better with Smart Heating Controls

Smart heating controls allow users to remotely control their central heating systems. It is, therefore an extremely effective and reliable way of putting the user in full control. The smart heating controls link up to the A-Rated boiler or renewable heating system to improve efficiency and reduce the amount of wasted heat. Furthermore, users can operate heating remotely by using devices such as a smart phone, tablet or a PC.

Installation Process

Installation of a ground source heat pump system is more complex than an air source heat pump due to some ground work being required to install the loop pipes.

The pipe loop can be buried in trenches horizontally, where quite a large plot is required, or inserted vertically into a borehole, where minimal space is needed, but specialist drilling rigs are required. 

The ground source heat pump system can be connected to an existing heating system, although some radiators may need to be changed.

Ground Source Heat Pumps may not be suitable for all properties, so we recommend you speak to our installation team for professional advice and a free of charge quotation. If A Ground Source system is not right for your property then we can offer a range of alternatives including Air Source Heat Pumps, Biomass Boilers and Solar systems.

How deep do Ground Source Heat pipes go?

Ground Source Heat Pumps systems are installed at a depth of about 1m below ground, if run horizontally, or up to a few hundred feet if installed vertically in bore holes. As such, you will need to consider the type of property in which you wish to install your new system. Ground Source Heat Pumps are installed at this depth to utilise the heat stored in the ground throughout the year, which is consistently around 10 degrees Celsius, regardless of the above ground air temperature.

Does a Ground Source Heat Pump require planning permission?

Planning permission is not usually required to have a Ground Source Heat pump installed on your property, thanks to the government’s Permitted Development Rights. These rights allow the improvement or extension of one’s home without planning permission. We do, however, always recommend to consult with your local planning office before commencing works.

What is Renewable Energy?

Renewable energy is from a source that is not depleted when used, such as wind or Solar. A fossil fuel such as oil or gas cannot be reused after it is burnt and is therefore is not a renewable energy. Visit our renewable energy page for more information – click here.

The best way to know what is best for you is for us to visit your property and advise you further. We can discuss the pros and cons of all technologies and will provide you with quotations, and performance estimates so you can make an informed decision.

Do Heat Pumps Really Work?

The are many horror stories of poor heat pump insulations, which do not work correctly and cannot heat the home or cost too much to run. Fortunately, there is also many examples of where they work very well. The difference comes from the technical knowledge to design and install the correct system, as well as ensuring the property is suitable in the first place. These poor installations come from companies who do not have the experience and knowledge to design and advise correctly and are installing system in inappropriate places. Our experience and knowledge will ensure that you get the right system installed and that we will be around to support you long after installation. If your property is not right we will advise and never recommend a system which is not suitable.


Should I wait for Prices to fall?

Prices on renewable energy installations has fallen significantly over the past 10 years, as uptake increases. We believe NOW is the ideal time to look at a renewable installation, because we have seen a fall in product and installation costs, but also a rise in fossil fuel prices, whilst at the same time the Government incentive schemes are still in place. So, this might just be the very best moment to make the move. (Current in Nov 2022)

Will Fossil Fuel Prices Continue to Rise?

Sorry we cannot answer that one, as no one else can for sure either. It is certainly our opinion that they are only likely to continue to rise, as extraction becomes harder, geopolitical tensions rise and as the demand for carbon reductions grows. Whilst Renewable Energy is free once you have the technology in place to harness it!


The best renewable energy option for your property will depend on your budget, property space, and how much money you want to save on energy bills. Although there is no one-size-fits-all solution when it comes to renewable energy, we provide the full range of renewable heating and energy saving solutions, with expert guidance and advice.

Ground Source Heating System

It was a big discision to have a ground source heating system installed into a new property we had just purchased. Heppelthwaite Green Building Solutions were outstanding from start to finish. They provided us with all the information, plans and advice, and were always available to answer any questions. The installation went smoothly. On time, very efficient and professional. They were very considerate of our neighbours, which was important to us, being new to the area. There was some digging required and our location had it’s challenges. However, it was no issue for Heppelthwaite and everything was handled extremely well. Great service and would highly recommend.
