It's inevitable with most homes, that some changes will need to be made to accommodate an air source heat pump but these changes are sensible when we're talking about lowering bills and being energy-efficient.
Heat pumps are rapidly evolving so the number of homes that are suitable is naturally growing...
Heat from the air is 'sucked in' and transferred to a heat exchanger that contains a liquid refrigerant which absorbs heat and evaporates to a low-temperature gas. The gas is compressed and in the process, its temperature rises. When the gas reaches the heat exchanger where its heat is transferred to cold water - in turn the water heats and is circulated around your central heating system or stored in a hot water cylinder. The technology is tried, tested and developing all the time. You can read more about air source heat pumps here...
Considerations when thinking about installing an air source heat pump in your home...
Before installing a heat pump your home needs to be adequately insulated. This is a key consideration. With more modern homes this isn't usually a problem due to building regulations and EPC ratings and higher quality glazing. For older homes we'd recommend a survey to see where insulation can be improved. The disadvantage of a poorly insulated home is that a larger heat pump would be required due to the loss of heat. We might recommend cavity wall insulation or replacement double glazing as a first step towards becoming more energy efficient.
If you have an old central heating system, we may recommend replacing radiators that are more suitable for use with a heat pump.
In extremely cold areas the efficiency of air source heat pump can drop but if you live in a city or town and have some outdoor space then you may find that the effect of climate is negligible, within reason.
