952035HS | Air to Water (A2W) Heat Pump

35kW Air to Water (A2W) heat pump - ducted stackable horizontal discharge model.

Save up to 75% on your energy costs when compared with an electric water heater. Heat pumps can also be used as a preheat to other boost fuel types.

This range of heat pumps is designed to draw its air from and discharge within basement carparks without flueing (unlike gas systems). As this is a stackable model it provides a reduced footprint when installed.

It delivers hot water up to 65°C, with a system Coefficient of Performance (COP) up to 4.0 and comes supplied with a built-in Rheem iQ controller with optional BMS capability. WaterMark certified with dipped evaporator coils to provide extra protection in corrosive environments.
