What about a heat pump water heater?
Heat pump water heater is a large free access to air heat, power consumption is only used to move the air compressor energy for energy, so the thermal efficiency is as high as 380%-600%, making the same quantity of water, the use cost of heat pump water heater electric water heater only 1/4, gas water heater 1/3.In addition, thousands of households, tens of thousands of commercial, to see how much water you use.
The utility model also eliminates the hidden dangers of poisoning and explosion of the gas water heater, and has no air pollution caused by the exhaust gas of the fuel water heater. The greatest advantage of an air heater is "energy saving."". Take specific data for example: 30 degrees Celsius temperature difference hot water prices are: electric water heater 1.54 cents / liter hot water (electricity price 0.42 yuan / degree); gas water heater 1 cents / liter hot water (gas 2 yuan / cubic meter);
The utility model has the advantages of energy saving, environmental protection and safety, and solves the problem that the solar water heater relies on sunlight to heat and install. Since the air energy heater is heated by exchanging heat through the medium, the electric heating element is not required to contact the water, and there is no danger of leakage of the electric water heater
