WHY CHOOSE AIR SOURCE HEAT PUMPS?

Heat pumps provide a carbon friendly way to heat your home, they are generally cheaper to run than traditional heating systems and significantly reduce CO2 emissions.


Air source heat-pumps are suitable for small and medium properties, they are cheaper and easier to install than ground source and don’t involve any additional ground-works but they are slightly more expensive to run in the winter months.

HOW AIR SOURCE HEAT PUMPS WORK?

  • In principle a heat-pump is like a fridge in reverse. The refrigeration system in your fridge cools the inside and generates heat at the back but a heat-pump gets cold outside and heats the house.

  • Air source heat-pumps extract energy from the air and have a heat exchanger and fan which cools the air as it passes through. Even on a cold day they can generate water up to +50C.

  • The unit is mounted outside and is powered by electricity but produces between 3 & 4kW of heat for every 1kW of consumed energy.

  • All heat-pumps work well with underfloor heating and can be connected to radiators but to maximise efficiency old radiators might need replacement.

  • Normally a new hot water tank is required.

IS THERE ANY SUPPORT AVAILABLE?

The Renewable Heat Incentive (RHI) is a Government incentive designed to encourage uptake of renewable technologies and ultimately contribute towards the reduction in CO2 emissions. It is available for Air and Ground source heat-pumps and subject to a successful application you could receive quarterly payments over a seven year period. 

More information can be found via Ofgem or the Energy Saving Trust:

RHI payments vary but for a three-bed house they are typically around £1,000 a year. A more accurate estimate can be obtained using the link below:
