The split heat pump unit has an external and internal unit. The external unit includes the heat exchange chamber and refrigerant. Therefore, the system is used in utilities/boiler rooms

Domestic heat pumps are usually small in volume and compact in size, which are not like the structure of a commercial heat pump with relatively larger spaces.

The inverter technology provides room for a speed compressor that modulates the output. This, in turn, enables it to decrease, increase, or decrease the speed in line with the home's heat demand.

A commercial heat pump's capacity and volume are larger than a domestic heat pump. There are even multiple units installed on the ground or roofs of commercial and residential buildings.

Swimming pool heat pumps transfer heat to the swimming pool. They use readily available heat and therefore use less electricity in heating the pool.
