Materials You Can Choose
In the case of the inner tank material we have enameled and stainless steel. The water tank outer coating can be in color-coated stainless steel or steel. There are white color steel finishes, silver, gray, and matte black. Custom colors are organized on demand. The all-in-one heat pump water heater has a heat exchanger that comes in microchannel or coils made of copper.


Environmentally Friendly, High Efficiency, Low Noise
The all-in-one heat pump water heaters are designed on the concept of exchanging heat passing through an evaporator embedded on the device itself and the outside air. The compressor is run with an electric motor to add heat as opposed to directly heating water. This design is very efficient in energy and generates no exhaust gases hence it is green. When in operation, there is only a faint humming of the compressor, hence a little noise production.
Copper Tubing vs Microchannel


All-in-one heat pump water heaters have a copper coil heat exchanger that is in direct contact with water and heat exchange depends on the flow rate of the water, which makes the heat exchange fairly efficient. Copper is highly water-resistant and offers excellent corrosion resistance, thus it is considered to be used in different water qualities. Even so, the expensive nature of copper will affect the manufacturing cost of the inner tank, and contract manufacturing takes time.
All-in-one heat pump water heaters Microchannel heat exchangers have been provided with several flow channels, which provide greater heat transfer area and efficiency. Unlike copper, aluminum has lesser corrosion resistance and must depend more on protective coating, so it is more likely to be used in locations with softer water. The low cost of aluminum, which is supplemented by the possibility to manufacture microchannels easily on a mass-scale, allows producing lots of them at low cost. This is perfect to use in bulk orders of OEMs, and is very cost-effective.
