| 摘要 | A heat pump water heater and a method for servicing the heat pump water heater are provided. The heat pump water heater includes an evaporator, a condensate collection tray, and a condensate pump for discharging collected condensate. Notably, the operating time of the condensate pump correlates to the amount of wet operation of heat pump water heater, and increased wet operation may correlate to corrosion and wear on the heat pump water heater. Therefore, an exemplary method contemplates determining an operating time of the condensate pump and, based on the operating time, determining and communicating a recommended service schedule. In addition, an operating parameter of the heat pump water heater may be adjusted, such as switching to electric heating when the operating time exceeds a predetermined threshold. | ||||||
