An electric heat pump system, for generating
hot water, suitable for domestic purpose.
The EcoSmart Heat Pump hot
water systems utilise latent heat in the air, to heat water.
They are available in a 250L storage capacity only.
The heat pump system contains extremely cold
liquid refrigerant, which travels through a copper pipe. The air
passing through this evaporator contains latent heat which is
absorbed by the refrigerant. A compressor then pulls the
refrigerant inside where it is compressed. As the pressure
rises, the temperature increases. From here the refrigerant travels
to the condenser, where the heat from the refrigerant is
transferred to the water tank. Finally an expansion valve
provides the pressure reduction to the refrigerant and the cycle
This system is a highly efficient method of
heating water, and it uses only a small amount of the electricity a
conventional electric hot water system uses.
