What is a ground source heat pump?

Renewable home energy in the ground beneath your feet. By tapping into stable underground heat, ground source heat pumps can efficiently heat your home and provide hot water. There are different installation methods available, from shallow ground loops in your garden to deeper closed-loop systems up to 150 metres under your home. At Geowarmth, we use advanced software and years of invaluable expertise to recommend the best solution for your needs.

What we offer

We will assess your property’s suitability and compliance, offering expertise as an MCS accredited installer to ensure you can benefit from the Government’s Boiler Upgrade Scheme, saving £7500 on your new ground source heat pump.

Our team designs and installs your system, including hot water cylinder and heating distribution if needed. We also offer remote monitoring, post install support and maintenance advice so your warranty remains valid.

For a large school in Northumberland we surveyed and then designed and installed two 75kW reversible ground source heat pumps. These were able to provide year round heating and cooling to the site.

New Build

Serving a new-build carbon neutral property we designed and installed a bespoke system with a 10kW ground source heat pump, a 500 litre hygienic thermal store and a 300 litre solar cylinder. The project also required underfloor heating and was complimented by solar thermal panels and a PV array.


What is a ground-source (geothermal) heat pump?

A ground-source heat pump, also known as a geothermal heat pump, makes use of the stable temperature of the earth’s subsurface to heat and cool buildings. It works by circulating a fluid through underground pipes to exchange heat with the earth, providing efficient heating in winter and cooling in summer.

How does a ground-source heat pump save energy?

Ground-source heat pumps save energy by leveraging the relatively constant temperature of the earth’s subsurface, which remains warmer than the air in winter and cooler than the air in summer. This allows them to efficiently extract heat for heating purposes.

Are ground-source heat pumps suitable for all locations?

Ground source heat pump suitability can depend on factors such as soil type, local geology and land availability. Generally, they are more commonly installed in areas with sufficient land space and where the subsurface conditions are favourable for heat exchange.

How do I know if I need an air source or a ground source heat pump?

This will likely depend on the outdoor space you have available and the geology under your home. Our team can advise which option is best for your home after completing a site survey.
