There are two main types of heat pumps:
Single-stage heat pumps operate at a single capacity level. They either are on or off, which can lead to temperature fluctuations and higher energy bills.
Two-stage heat pumps can operate at two capacity levels – low and high. The low-stage setting provides consistent heating or cooling for mild weather conditions, while the higher setting activates for colder or hotter weather, ensuring efficient temperature control in all conditions. Two-stage heat pumps tend to be more energy-efficient and offer better temperature control than single-stage heat pumps.
