Introduction

The CAWH water heater stores and heats water for sanitary purposes.
Air from the installation room is forced through an evaporator by two fans (3) and this
thermal energy is transfered to the heat exchanger wrapped around the tank via a
refrigerant circuit.
Cold water entering the tank through the water inlet (4) is heated by this heat exchanger
assisted by two additional electric elements.
