Both the heating water tank and the water storage tank are equipped with polyurethane insulation layer, the heat recovery rate can be as high as more than 70%, and a large amount of excess heat energy can be recovered.

2) Energy saving and environmental protection: there is an automatic temperature control device and an automatic water level control device to control the temperature and water level of the heating water tank. The heating water tank is connected to the domestic water heater. According to calculations, the recovered heat can heat 73.5L of water from 20 to 45 degrees per day for the whole family to take a bath at night, save 2-3 degrees of electricity per day, and reduce the heat emission to the atmosphere by 7.7364×10 ⁶ J.

3) Low cost and long-term use value: the external unit of the air conditioner is simply refitted, with low cost, simple structure, and long-term use value, which is convenient for repair and maintenance. In addition, the water storage tank and the domestic water heater can share a water tank, which has the advantages of The advantage of saving space.

4) Fully automatic operation: The circulation between the heating water tank and the water storage tank is all automatically controlled, without manual adjustment. At the same time, there is an auxiliary heater in the water storage tank, which plays the role of final adjustment of the water temperature. source of water.
