Simply put, Heat Pumps are devices that extract heat from one source and transfer it to another. In the case of the technology available right now, there are 2 options in the market, one uses heat from underground, the other extract it from the surrounding air.
Looking very much like a wall mounted or free standing air conditioner, and functioning in a very similar way, Air Source Heat Pumps (ASHP’s) are primarily used for home heating, but can also help with hot water around the home, such as for warm air systems or underfloor heating & radiators.
Although they do need electricity to run, they are efficient. On balance, the heat it produces outweighs the power it consumes – if your home has solar panels, then this will greatly help to provide the power for the pump.
Homeowners may also be eligible to claim tariff payments from the renewable Heat Incentive, which is similar to the tariff for other renewable energy home improvements.
