In the first 5 days a Inver F pool heat pump runs at 100% capacity and heats up the pool to the set temperature. In the next 175 days, it runs at AVERAGE 50% capacity by AVERAGE COP 11.5 to maintain the desired pool temperature. So the AVERAGE COP is double of On/Off heat pump
When maintaining pool temperature at AVERAGE 50% capacity, AVERAGE sound pressure of a Inver F pool heat pump can bring you 10 times quieter swimming environment and more friendly neighborhood than an On/Off pool heater.
When Inver F pool heat pump turns on, the current will start from 0A and go up slowly to rated current in 2 minutes. It will not affect the house electricity system, while the frequent start current of On/Off heat pump is 5 times of rated current, it is a burden to the electricity system.
