What do I need to know about a heat pump?

To explain the operation of a heat pump, it is best to make a comparison with a conventional refrigerator. After all, both use the same principle. Your refrigerator gets cold thanks to the evaporator in the freezer compartment that contains a refrigerant. Your vegetables and other products give off their heat. To do this, it uses a special liquid that absorbs this heat and transports it outside the refrigerator.

The only component of a heat pump that consumes energy and thus determines energy consumption is the compressor. This energy is used to transfer heat and not to generate it. So that is the major difference from electric heating that leads to the higher efficiency.
