Heat Pump Hot Water Systems

Electroheat Hot Water System (HWS) adopts heating methodology via ambient air source. With air possesses excellent trait in absorbing and transferring energy, the HWS is a highly efficient mean of water heating. Due with its low operating cost, the power consumption of HWS makes up only a minimal portion of the power utilized by conventional heating approach such as natural gas and electric. HWS also resulted in little carbon emission, which makes it an environmental friendly method of producing hot water.

Working principle

Hot air is blown over the evaporator coil, transferring heat energy from the ambient to the refrigerant, whereas the cooled air will be rejected. Heat energy will then be carried by the refrigerant to condenser coil, where heat exchange happens between the coil and circulating cold water from water tank. Through this process, heat is pumped from one place to another.


Heat pump uses the available and unwanted heat energy from ambient to heat up the water. Instead of converting electrical energy to heat energy at almost one to one ratio, it uses much lower electrical energy just to move heat from one place to another. In long term, the saving can be substantial.


Cost effective heating
The heating load utilized by HWS only lies from operating the compressor and fan with low amperage. In comparison to other means of heating water, Waterco HWS saves up to 83% over propane gas, 58% over natural gas and more than 500% over electric heaters in terms of power consumption.
Energy efficient heating
Waterco HWS only uses portion of the energy used by gas and electric heaters to produce the same amount of heat. Unlike solar heating, the HWS does not rely on the presence of sunlight for heat.
The R417a used in the HWS as heating media is a high performance refrigerant, and at the same time being Ozonefriendly as compared to other conventional refrigerants.
Hot water on demand
Storing of heated water inside a tank assures the availability of hot water for various application.
