What is a Heat Pump Heating System?
A heat pump heating system is an energy-efficient technology used to heat (and often cool) buildings by transferring heat rather than generating it through combustion. Unlike traditional heating systems that burn fuel or convert electricity directly into heat, heat pumps move heat from one place to another using a refrigeration cycle. How Heat Pumps Work Heat pumps operate on the principle of heat transfer, which is facilitated by a refrigerant circulating through a cycle of evaporation and condensation. The key components of a heat pump system include an evaporator, a compressor, a condenser, and an expansion valve. The Heat Pump Cycle Evaporation: The refrigerant absorbs heat from the outside air (even in cold weather) and evaporates into a gas in the evaporator coil. Compression: The gaseous refrigerant is compressed by the compressor , raising its temperature and pressure. Condensation: The hot, high-pressure gas flows into the condenser coil inside ...
