While heat pumps have an important role to play in reducing our dependence on fossil fuels, the technology is still relatively unknown. There was a really interesting survey in December 2018 that found only 27% of people were aware of air source heat pumps, which rose to 33% for ground source heat pumps.
However, the technology is still relatively unknown, and myths about heat pumps have started to circulate. We are here to set the record straight and tell you the TRUTH about air and ground source heat pumps.
Myth 1 - Air source heat pumps are noisy
This is probably one of the most common myths you’ll hear. Today’s heat pumps have changed and they are no longer big, bulky and noisy pieces of equipment. On the contrary, they are now compact, energy efficient and make about the same amount of noise as a refrigerator. If yours is correctly installed, you shouldn’t be able to hear the sound indoors.
Myth 2 - They only work with underfloor heating
Air source and ground source heat pumps are both compatible with underfloor heating and radiators. Larger radiators, which give out heat at lower temperatures over a longer period of time, can actually help to maximise the benefits of heat pumps.
Myth 3 - Heat pumps are too expensive
The price of the initial installation may be significant, however, there is financial support available depending on where you live.
For example, the Home Energy Scotland loan offers up to £10,000 to Scottish homeowners. Click here to find out more.
Myth 4 - Heat pumps aren’t efficient through cold winters
Because the ground stays at a fairly constant temperature under the surface, ground source heat pumps work perfectly well all year round.
The efficiency of an air source heat pump does reduce as the outside air temperature falls. That being said, they are still capable of extracting heat from the air when temperatures are as low as -15°C.
Myth 5 - A heat pump can only be installed in new houses
Heat pumps can actually be installed in most properties, regardless of the type of building or how old it is, from semi detached houses to high rise flats. You should always check whether you need planning permission from your local planning authority before installing any renewable system, especially if you live in a conservation area or listed building.
