The units are rated for heating or cooling not electrical power. You divide by the COP to get power consumption.

Your example means 6kW of heating consumes 6kW ÷ 4.44 = 1.35kW power consumption.

This COP does not take into account the power used by the electrical defrost element on the outdoor unit.
