How can the cop be maximised for a heat pump
WebHeat Pumps and Energy Consumption. It is possible for heat pumps to reduce energy consumption by up to 72%, depending on the type of pump you are using and also how insulated your home is. The COP for heat pumps tends to range from 3.2 to 5.2, depending on the same criteria as before. WebThe system runs a sterilisation cycle after every 4 th compressor start where it takes the water flowing from the heat pump to the tank up to around 64 o C. This is to try and inhibit the growth of Legionella bacteria in the hot water system. It would be our conclusion though that this sterilisation cycle happening after every 4 th compressor ...
