One common question from homeowners considering making the switch to a sustainable form of heating is whether ground source heat pumps could be a good choice for them.
Here at Lewington, we’re pioneers in sustainable heating solutions, having founded Lewington Renewables back in 2000. Of course, we also continue to install a great many modern boilers, so when it comes to making the best choice, you can be confident that we’ll point you in the right direction for your heating needs.

What is a ground source heat pump?
A ground source heat pump is a renewable energy system that extracts heat from the ground to provide heating and hot water for your home. It works by circulating a water and antifreeze mixture through underground pipes and pumps which absorb heat from the earth in your garden. This hot water is then transferred into your central heating system, providing consistent and sustainable warmth throughout your home. Once it’s been used, the fluid flows back into the ground loop to reheat. This means that after your system is up and running, all you have to pay for is the electricity used to run the compressor!
The technology is reliable, efficient, and can massively reduce your carbon footprint. But like any heating solution, it’s not one-size-fits-all. So, what should you consider when deciding whether a ground source heat pump will suit your home?
Outdoor space
Ground source heat pumps use underground pipes called ground loops, which absorb the earth’s heat. This means outdoor space is required, so if you have a spacious garden or outdoor area, clearly this is a significant plus point. The size of your pipe system will depend on your home’s heating and hot water needs and our expert heating engineers can advise you on this.
Installation costs
Domestic ground source heat pump installation is more expensive upfront compared to traditional boilers or air source heat pump installation. However, for those who come to the informed conclusion that it’s the right decision for them, it’s an investment that can pay off in the long term through lower energy bills and a reliable, low-maintenance system.
Currently the government’s Boiler Upgrade Scheme offers significant savings towards the cost of installation and there is no VAT payable on the costs you do pay, meaning now is a great time to act. For the very latest information on the savings available, please take a look at our funding page.
Your existing heating system
Ground source heat pumps work with most heating systems, but they can be particularly efficient when working in conjunction with underfloor heating or large radiators, as these systems distribute heat at lower temperatures. As with all heating systems, if heat escapes too easily the pump will have to work harder, resulting in reduced efficiency, so to get the most out of a ground source heat pump, it also helps if your home is well insulated.
Should I choose a ground source heat pump or an air source heat pump?
Both ground source heat pumps and air source heat pumps offer sustainable alternatives to fossil fuel-dependent traditional heating systems. But how do they compare?
Installation process
As ground source heat pumps require groundwork, the installation process is more complex and costly, but it can be a fantastic long-term solution for homes with sufficient outdoor space.
Air source heat pumps are easier and quicker to install as they don’t require large amounts of outdoor space, making them better suited for properties with limited space or smaller budgets.
Performance
Ground source heat pumps are highly efficient all year round as ground temperatures remain consistent all year. However, although they rely on extracting heat from the outside air, you can expect a consistently reliable performance from air source heat pumps, even in the coldest of winter temperatures. As a result, both types of systems offer a reliable source of heat for your home.
Why choose a ground source heat pump?
Once you’ve established that your property is suitable, a ground source heat pump offers several great benefits:
Energy efficient heating
Ground source heat pumps can deliver four times more energy than they consume. This can result in significant savings on energy bills compared to traditional heating systems.
Reduced carbon footprint
Transitioning to a ground source heat pump is a step towards a greener future, lowering your household emissions dramatically.
Longevity
Ground source heat pumps are designed to go the distance with a hassle-free lifespan of up to 25 years. As with any heating system, we recommend an annual service to ensure your system is working at its optimal level and to troubleshoot any potential issues.
So, is a ground source heat pump right for you?
Ultimately, the answer depends on your property, budget and priorities. If you have enough outdoor space, a well-insulated home and the budget for installation, a ground source heat pump could be an excellent choice. However, if space or initial costs are limiting factors, an air source heat pump may be more practical.
Whether you choose a ground source or air source heat pump, both options offer a cleaner, more sustainable way to heat your home. However, it’s also important to factor in a modern traditional system as part of the decision-making process.
