DuoHeat pumps are uniquely designed and manufactured by Hot Water Heat Pumps Ltd. Our first DuoHeat unit was successfully built in Auckland in 1983 as a combined pool and domestic hot water system.
Offering all the benefits of our standard heat pumps, DuoHeat models eliminate the need to invest in two separate units. They deliver a smaller footprint, reduce equipment redundancy, and provide substantial long-term cost savings.
