The frequency and flow changing heat pump water heater takes the frequency-changing compressor as the power source of the system, takes the electronic expansion valve as a throttling device and uses the water temperature sensor to prevent freezing. Compared with combustion gas, fuel oil, coal or ...
Traditional storage tank systems consist of a large insulated tank that stores heated water until needed. A gas burner or electric heating element heats the water within the tank to the desired temperature. These systems are inexpensive to purchase and install but may have higher operating costs du...
