Single-stage and two-stage heat pumps differ in their operation and offer distinct benefits::
Single-stage heat pumps have one output setting. They either run at full power or are off, which might impact comfort and reduce efficiency.
Two-stage heat pumps can operate at two capacity levels – low and high. The lower setting provides gentle heating or cooling for mild weather conditions, while the higher setting activates for colder or hotter weather, ensuring optimal comfort in extreme climates. Two-stage heat pumps tend to be more energy-efficient and offer better temperature control than single-stage heat pumps.
