If your home doesn’t offer suitable roof space and orientation for installing solar collectors, Airoheat is the next best choice in environmentally friendly water heaters, without the need for solar panels. Working like a refrigerator but in reverse, it takes air in from outside the tank and uses it to heat water. Its patented in-tank heating coil is fully immersed in water, ensuring direct heat transfer.

This eliminates exposure to heat loss issues often associated with other styles of heat pumps. An iconic brand since 1915, Dux is committed to producing high quality water heaters and to the on-going development of new products for the New Zealand market. Dux water heaters are manufactured in a state-of-the-art facility using a Quality Endorsed Company production system. This ensures that customers have purchased the highest quality water heater available.
