Kensa's Evo ground source heat pump installed in a home

Your choice of heating system could be of great consequence for your building project for years to come. Ground source heat pumps have low running costs, minimal maintenance and a long lifetime AND qualify for a generous income from the Renewable Heat Incentive. Find out if your project could benefit from ground source.

Environmental pressures have boosted the appetite and need for low carbon low polluting renewable technology in both rural and urban locations, in particular ground source heat pumps. This technology is also a favourite for its low running costs, minimal maintenance and long lifetime. And Government’s Renewable Heat Incentive income makes the financial case for ground source heat pumps even more appealing for self builders; for those with one building they can enjoy a guaranteed income for 7 years, and for those with more than one dwelling, connecting individual heat pumps in these dwellings to shared pipework in the ground qualifies for 20 years of income through the Non Domestic RHI.

With the case for ground source heat pumps clear, Kensa Heat Pumps has come up with three simple top tips to ensure your project is suited to ground source heat pumps. If you tick all these boxes, you can most certainly benefit from this rewarding and renewable home grown technology for years to come.


Top Tip #1: What are the insulation levels of the property?

Your home’s efficiency will also impact the size of the ground source heat pump you require – the lower your heat demand, the smaller and cheaper the heat pump, and the less work it needs to do, which all in all means a far cheaper to run home.

Furthermore, the more efficient your heat pump, the more you earn through the Renewable Heat Incentive. A win-win.


Top Tip #2: Strive for optimum efficiency

Selecting whether you have underfloor heating or radiators, and what floor covering you use, can all effect the efficiency of your ground source heat pump system, which ultimately impacts your fuel bills.

Typically, well insulated homes with underfloor heating downstairs and radiators upstairs (oversized if a renovation) return the best results.


Top Tip #3: Your land is worth more than you think

With all the free renewable heat coming from the ground I bet you didn’t expect to be an owner of your own mini gold mine did you?!

There are many options to extract the heat from the ground, from space-saving boreholes to cost-effective slinky trenches, to water sources (lakes, streams, ponds etc.) which provide the most efficient heat extraction for the heat pump.
