How Heat Pumps Operate
Heat pumps transfer heat instead of generating it. They absorb heat from one location and release it in another.
- Evaporation Stage: A refrigerant absorbs heat, turning from liquid to gas in the evaporator coil.
- Compression Stage: The compressor increases the pressure and temperature of the gas, circulating it through the system.
- Condensation Stage: The hot gas loses heat in the condenser coil, turning back into a liquid while warming the home.
- Expansion Stage: The refrigerant expands, reducing pressure before returning to the evaporator, continuing the cycle.
Heat pumps are efficient, typically providing three to five units of heat for every unit of electricity consumed. Understanding their types and operation helps you make informed heating choices.
