Price
Expand to view more details.Prices are based on what we found on retailer or manufacturer websites in February 2024. Manufacturers often sell direct to installers, so for some models the price isn't publicly available.

Model type
Integrated models are all-in-one units with the heat pump compressor at the top of the tank. Split systems have separate compressor and tank components (much like a split system air conditioner), which can allow the tank to be installed indoors.
Capacity (L)
The capacity of the tank, in litres.

Suitable household size
The household size for which this system is suitable, based on manufacturer claims. A small number of manufacturers don't provide this information. In these cases, we calculate an approximate household size based on the capacity of the tank. To estimate your household's hot water usage, assume 50L of hot water per person per day, plus 50% for occasional heavy usage days.
Defrost cycle
Defrost cycles are essential in cold areas, where icing can occur on the compressor unit.
Minimum working ambient temperature (°C)
The claimed minimum ambient temperature in which the heat pump hot water system will operate.
Maximum working ambient temperature (°C)
The claimed maximum ambient temperature in which the heat pump hot water system will operate.
Refrigerant type
The refrigerant type used by the heat pump compressor. R290 is propane and R744 is refrigerant grade CO2, both considered reasonably environmentally safe (low global warming potential). R134a is tetrafluoroethane, a hydrofluorocarbon, which has higher global warming potential.
Country of origin
Country of manufacture, where stated by the manufacturer or retailer.
