To get the same heat, the power consumption of the heater is 3.5 times that of the fixed-speed hanging air conditioner and 4.7 times that of the variable-frequency air conditioner.

See the picture for details.

Two sets 1 energy-efficient constant-speed air conditioning consumption 1480W, which can achieve 5 180WD? Heat. That is, the power consumption is 1000W, and the heat of 3500W can be obtained.

The electric heater consumes 2000W and can only get 2000W of heat. That is, the power consumption is 1000, and the heat obtained is only1000 w.
