In-depth guide to heat pumps

In a heat pump the amount of heat produced for every unit of electricity used is known as the Coefficient of Performance (CoP). So, if a heat pump has a CoP of 3.0, then it gives out three units of heat for every unit of electricity it uses. Every heat pump has a published datasheet telling you what its measured CoP is.
