Energy efficiency of the heat pump
The first indicator of the energy efficiency of such pumps is the COP (coefficient of performance) or heating value. It represents the ratio between the energy recovered and the electricity used by the appliance to operate. Always compare the COP value against the same measurement standard, taking into account the same temperature conditions.
Temperature limits of heat pumps
There are different types of heat pumps. They are used for space heating as well as for domestic hot water. That is why you should be careful when choosing the right type of pump for your needs. For example, an air/water pump can reach very high inlet temperatures even at lower ambient temperatures (60°Celsius at ambient temperatures of 15° below zero).
So, before you buy, check the heating capacity of the air/water pump at outdoor temperatures below freezing, as most manufacturers quote the heating capacity of the pump at 7° Celsius (a temperature at which heating is almost no longer needed). It will help you to make your decision if you first ask the seller for information on the heating capacity of the appliance at a lower outdoor temperature (e.g. -15°C). Only then will you be in a better position to compare the heat pumps with each other.
