The high-density micro-channel heat coils with multi-flow allow the refrigerant and the surface of the enamel water tank to have a large-area heat exchange, which highly improves the heat transfer efficiency. MicroChannel heat coil greatly enlarges the available contact surface between inner water tank and heat coil thus enhance the performance of heat pump water heater. The COP of this kind of unit can reach to 4.16.

During water heating, the all in one series can automatically calculate and analyze its current operating conditions, then adjust the power input to achieve an optimal COP .Under ideal conditions, Smad R290 all-in-one heat pump water heater can achieve a high COP of up to 4.16, which can significantly help to reduce energy consumption and save the energy bills for users in the long run. The excellent energy-saving effect makes the water heater stand out from the normal water heaters in the market.

The enamel coating design makes the welding line of steel plate separated with water, so it has no risk of corrosion, scaling, leakage, etc. Thus, the water tank is of high pressure and fatigue resistance which passes 250,000 times pulse test.

The water heater comes with an inbuilt touch LCD display. It is very user friendly and boast a range of operation modes and settings to ensure the lowest energy consumption.
