air source heat pump
The 'Efficiency' of air source heat pumps is measured by the Coefficient of performance (COP). A COP of 3 means the heat pump produces 3 units of heat energy for every 1 unit of electricity it consumes. Within temperature ranges of -3°C to 10°C, the COP for many machines is fairly stable at 3-3.5.
In mild weather, the COP of an air source heat pump can be up to 4. However, on a very cold winter day, it take [...]
