Air to Water (A2W) Heat Pump
65°C hot water in a super-efficient and super-compact package.
Up to 25% of the operating cost of an electric water heater with a Coefficient of Performance (COP) of up to 4.
This Air to Water (A2W) heat pump range is designed for both vertical or horizontal discharge options, with a discharge fan option available in both ducted and non-ducted versions. Horizontal discharge models can also be stacked two high to reduce plant footprint (suffix 'S').
The automatic defrost function allows continued performance in low ambient temperatures by diverting a portion of the hot refrigerant to evaporator coil to melt any ice which may form. In addition, the evaporator is dipped to provide extra protection in corrosive atmospheres.
