What is a ground source heat pump (GSHP)?

With the growing focus on renewable energy and the quest to become more energy efficient, heat pumps are becoming more commonplace in the world of domestic heating. The advancement in technology, plus government incentives such as the Boiler Upgrade Scheme (BUS), has made them a much more viable option.

Heat pumps are most commonly found in 2 forms:

Both work in the same way but, as the name suggests, they generate energy from either the air or the ground.

The crucial difference between a GSHP and a traditional boiler is that it is powered by electricity rather than burning fossil fuels, offering both a cost and carbon emission saving.

What are the

Benefits of Ground Source Heat Pumps?

Reduced Fuel Bills

Depending on your current energy supply, a heat pump has low running costs and can reduce your heating energy bills. Typically, the largest savings are seen when replacing oil, LPG, electric, or old/inefficient natural gas boilers.

Reduced Carbon Emissions

A heat pump is a source of renewable energy and does not burn fossil fuels. As a result, switching to a ground source heat pump can drastically reduce your home’s carbon emissions.

Minimal Maintenance

A yearly inspection is required in order to ensure the heat pump is operating effectively and safely, and to maintain the relevant guarantees. Therefore, the overall running costs are lower than maintaining a gas boiler.

Greater Energy Efficiency

A GSHP is undoubtedly more efficient than gas central heating, and generally more efficient than an air source heat pump. This is because the temperature below ground is constant throughout the entire year whereas the air temperature obviously fluctuates quite drastically, thereby affecting the efficiency of an air source heat pump. They also tend to last longer as they are not exposed to the elements like their air source counterparts.

How do ground source heat pumps work?

Ground source heat pumps work by absorbing natural heat energy from the ground to provide space heating and hot water.

A system of pipes is run underground in the form of horizontal loops or vertical boreholes, through which a mix of water and antifreeze is pumped. The liquid absorbs the natural heat from the ground, is compressed and then passes through a heat exchanger, which is powered by electricity. This is used to heat water which is then used via your heating system and hot water. 

As with air source heat pumps, ground source heat pumps are more efficient when producing water at lower temperatures – this makes them ideal solutions for homes with underfloor heating, but also work with conventional radiator systems.

Ground source heat pumps FAQs

Both have pros and cons. GSHPs are more efficient due to soil temperature being more constant than air temperatures, however, they require a lot of space and are expensive to install, so for average sized properties an air source heat pump is a better solution.

Yes, the pipework (either horizontal loops or boreholes) are buried at a depth where the ground temperature is consistent all year round, thereby the winter months do not effect the efficiency of ground source heat pumps. This can be viewed as both a postitive and a negative thing - for example if you are looking to heat a swimming pool during the summer months then an air source heat pump will be more efficient than a ground source heat pump due to the ambient temperature of the air vs that of the ground.

Yes. A GSHP runs on electricity so generating your own power will make your property ever more self-sufficient and green!

Horizontal GSHP loops are generally buried of a depth of around 1.2m (depending on the ground type and condition) and can cover an area of anything up to 100m x 100m depending on the size of the property. Borehole systems can vary between 80m to 200m in depth and multiple can be used to heat larger properties.

MVHR can be installed in a broad range of commercial properties, with many benefits. Following the pandemic, constant ventilation is of utmost importance in public buildings. MVHR also reduces a buildings heating and cooling demands, so offers a valuable cost and energy saving.

Yes, a GSHP can provide hot water for a central heating systems containing radiators. A system designed for radiators will typically be designed at between 45-50 degrees celsius; as part of our design process, we will ensure all radiators are sizes correctly.

Yes, a GSHP can even be used as a cooling system in warmer months.

According to the Energy Saving Trust, a GSHP can save you up to £870 per year when replacing an old gas boiler (correct as of October 2022).

Fitting underfloor heating is a more efficient heat distribution solution than traditional radiators as it requires lower temperatures. Heat pumps operate at their most efficient at lower temperatures, so it makes an ideal pairing.

You need a large plot of land for a GSHP. Just how much land depends on the size of your property and whether you opt for horizontal loops or vertical boreholes. Horizontal loops are most common and cheaper to install, and require anything up to 1,200 square metres. You will also need plant room space for the pump which is larger than a traditional boiler, sometimes as large as a kitchen appliance.

There are two instances where planning permission is required for GSHP installation - if it covers more than 0.5 hectares of land, or if you live in a listed building.

The Boiler Upgrade scheme offers £6,000 towards a renewable heating system such as a ground source heat pump. The installer must be MCS accredited, like Cinergi.
