How it works
The heat pump water heater uses unheated air to prepare domestic hot water.
Heat energy extracted from the ambient air is absorbed by the refrigerant through heat transfer at the
Evaporator. This energy is concentrated by the Compressor and then transferred by the Condenser into
the hot water tank. This cycle is repeated after the refrigerant has cooled. A low energy fan ensures
ambient air movement across the Evaporator.
The air is propelled through the appliance
by a fan, which ventilates the various parts,
including the evaporator.
As it passes through the evaporator, the
coolant evaporates and absorbs calories
from the incoming air.
The compressor compresses the coolant,
thereby increasing its temperature.
This heat is transferred to the domestic
water in the tank by the condenser.
The coolant expands in the thermostatic
expansion valve and cools down. It is then
ready to absorb heat again in the
evaporator.
The colder the air, the more difficult it is to extract the calories. Similarly, the higher the hot water setting,
the more difficult it is for the heat pump to transfer the extracted calories.
