The Dux Airoheat® is the most efficient heat pump water heater in its class due to the New Heat Technology or NHT.
Lets consider the efficiency of Airoheat® in two parts.
The first part is the efficient creation of the heat using state of the art components.
The second part is how & where the heat is transferred into the water.
What makes Airoheat® so efficient is that the heat transfer occurs within the water inside the tank. As a result it gets direct heat transfer and isn’t exposed to some of the heat loss issues
associated with other styles of heat pump water heaters.

Airoheat® Subzero now includes an innovative de-icing function so there's no need for a back-up element.
Management by the innovative Hotlogic® controller, allows the Airoheat® to keep running when the air temperature drops below zero.
It is also lighter to make it easier to handle.
More efficient than the original Airoheat®, the Subzero receives an additional 2 RECs points.
Easy installation. An easy change over from an electric storage water heater. Significantly lower on electrical consumption. No solar panel needed! Quiet operation. Full mains pressure delivery.
