What brand of heat pump water heater is better for hotel to choose for centralized hot water? It has high requirements for sanitary standards, high outlet water temperature and water supply speed, and can run at MINUS 10 degrees. Because it is used in the north and the winter time is long, it is recommended to choose ultra-low temperature units, and the minimum working environment can reach -20 degrees. It has good efficiency in low temperature environment.

According to our long-term use data in Wuxi, the average annual power consumption of hotels using conventional air energy units is about 15kWh/ ton (excluding backwater energy consumption). General commercial electricity consumption is about 1.0 yuan/kwh, that is 15 yuan/ton (water temperature is 55 degrees).
