Ground source heat pumps are excellent low-carbon heating systems that are able to extract warmth from the ground by using buried pipework rather than producing it by burning fossil fuels, becoming a highly efficient and cost-effective option for your home.
Given the fact that they are able to extract heat stored in the ground to heat up your home, they take advantage of the relatively consistent temperatures of the earth throughout the year, making them less susceptible to changing adverse weather conditions during the winter season
In addition, once installed, there are very few running costs, and as this type, among various heat pumps, is eligible for the Boiler Upgrade Scheme, you can actually earn a bit of additional income on the side. However, the initial price of a ground source heat pump is high, which can turn some homeowners away.
In order to help you make a final decision, in this article we have elaborated an extensive guide that covers all the advantages and disadvantages to know before purchasing your next best ground source heat pump.
Having said this, the final decision will ultimately depend on your personal circumstances, for this reason, it’s always advisable to gain insight from professionals in the field.

A ground source heat pump has a quite simple functioning. In fact, it works the same way your fridge does: it transfers heat from one space to another. The main difference relies on what those spaces are. In the case of the fridge, it extracts heat from inside the fridge and places it outside.
A ground source heat pump (GSHP) transfers heat from the ground to your house. The constant year-round temperature of the ground—approx. 8-12°C—heats up the underground pipes that are able to capture this heat, heat it up further, and transport it to the wet central heating system in your house, such as radiators, underfloor heating, showers, and faucets.
The video below explains how a ground source heat pump works:
Of course, such a device requires a specialist to carry out the installation. The difficulties show up at the external part of the GSHP installation. It is necessary to excavate and to distribute an extensive net of pipes (those that will take heat to or from the ground). Fortunately, this doesn’t generate major environmental issues.
A GSHP is a versatile and eco-friendly heating and cooling system, though it also has its disadvantages. So let’s list both its pros and its cons.
The following list comprises what we consider are some of the most outstanding advantages of GSHP:
The list below shows the probably most concerning disadvantages related to GSHP
A ground source heat pump is typically great for new builds rather than retrofits. This is due to the extensive underground piping work that needs to be done in order to install the system, whether you choose a vertical borehole or a horizontal trench. It is best to have an installer come and inspect your property and help you determine the most suitable ground source heat pump for your home.
