Characteristics of water heater with heat pump

AQUA HP is a water heater with heat pump for hot water preparation from the ambient air. 

Design of water heater with heat pump

The unit consists of an enamelled steel tank for hot water, an air-water heat pump and an auxiliary electrical heating element.  The heat pump is located on top of the heater tank, and its cover is fitted with inlet and outlet vents for air circulation onto which ductwork can be installed optionally for the desired mode of operation.  The electrical heating element designed for hygienic protection and rapid heating of the tank, and is located approximately in the middle of the tank.  On the front side of the heater there is a display of the appliance controller and on the front side inside the tank a magnesium anode is installed to protect it.

The water heater with heat pump is supplied with accessories, such as plastic transition fittings for water inlet and outlet of the heater, plug on circular outlet and hoses to drain condensate from the heat pump.
