Heat pump
A heat pump is a non-combustion heating system that extracts heat from the exterior environment to heat the home. In other words, it's the "opposite" of a refrigerator. Heat is usually captured from the air (aerothermal) or the ground (geothermal). Heat may be provided in the form of hot air or hot water. Its energy, economic and ecological value is not always clear, and must be studied case by case.
A heat pump operates in the same way as a refrigerator. The fluid circulates on the exterior and takes the temperature of the air or water. It is evaporated after the pressure imposed by the compressor drops (its piston descends). Its temperature lowers, the external source cools. When it rises, the piston warms the fluid that is then sent throughout the home. © AFPAC
