Air (Heat Pump) Water Heater Advantages

1. Green Low-Carbon

Use environmentally-friendly refrigerants R134a, R410a, R407c.  Zero discharge of waste water, waste heat and toxic gases.

2. Energy Efficient, Elegant

Consumes only about 1/4 of the energy used by ordinary electric water heater, 1/5 of that of gas water heater each day.  Needs only to pay about 25% of your hot water electricity bill.  An ordinary 3 people household can save about 1,500Kwh annually.

3. High Performance Configuration

Titanium Stainless Steel Double Tanks

Corrugated fin Evaporator

Uses top Mitsubishi dedicated heat pump compressor; Large corrugated fin type evaporator; Titanium stainless steel double water tanks;  Titanium-Nickel alloy external heat exchanger tubes instead of copper tubes. Coefficient of performance (COP) of up to 4.2.  Expected life of equipment up to 15 years with low maintenance cost.

4. Safety

With built-in multiple protection features to immediately stop operating due to faults such as: abnormally high or low exhaust temperature; compressor overheating, electric current too high; refrigerant  pressure abnormal; water flow abnormal or temperature too high.  The controller will also display the warning code for easy identification of the reason and for easy repair.

The hot water tank is completely isolated from the main compressor unit. No electrical heating element in direct contact with water and the water quality is clean.

Hot water energy consumption typically accounts for about half of an average household’s total monthly energy consumption. Fuel type water heater has only about 75% of energy performance and that of ordinary electric water heater is about 95%.  But our air (heat pump) heater has an excellent performance of 400%. This is more than four times of the ordinary heaters. Therefore, it can reduce energy costs significantly.  For example an ordinary electric water heater will use 4.89Kwh to raise 100L of 15 ℃ water to 55 ℃.  But an air (heat pump) heater requires only about 1.22 Kwh.
