How much heat is provided?
A heat pump cannot be depended on as a sole source of heat for your home. Given that it heats water to a lower temperature compared to a traditional boiler, it will not provide a hot enough water temperature for bathing or washing alone. But it can work wonders as a heat source when teamed up with underfloor heating or large radiators.
Heat pumps are capable of heating warm water to somewhere between 35oC – 45oC; but this temperature is much lower than that achieved by a standard domestic boiler. While heat pump units are capable of generating higher temperatures it should be kept to a minimum so the CoP (Coefficient of Performance) is not compromised.
CoP measures how efficient a heat pump is. If the heat pump has a CoP of three it means that for every kilowatt of electricity put in, you get three kilowatts of heat energy back.
Heat pumps are ideally suited to new builds or homes where there is no mains gas supply. It’s worth remembering that to get the best out of your heat pump your home must be very well insulated, otherwise the performance of your heat pump will be affected.
