How Do Heat Pumps Work?

Heat Pumps are an extremely effective method of generating heat for your home. Using some motive power to run a refrigeration compressor, we can collect additional free heat from outside sources such as the air, soil, rock or lakes.

In the evaporator (heat exchanger) the energy transfers from the cold medium to the refrigerant. The refrigerant will then evaporate. The refrigerant is transported in the circuit by the compressor to increase the pressure and temperature of the refrigerant. In the condenser (heat exchanger) the refrigerant cools and condense. The energy is then transferred from the refrigerant to the heating system of the house, hot water system or air system The expansion valve regulates the mass flow of the refrigerant to maintain the pressure difference between the high pressure and the low pressure side.
All around us are sources of energy in the form of stored solar energy, which even if they have a low temperature can provide us with heat. But how can a few degrees above zero gives us energy to heat radiators and hot water. Let us explain!
