4.2 kWMitsubishi Electric MFZ-KW 4.2kW Floor Console
The 4.2 kW step in the floor console range, covering roughly 27 to 34 square metres. Useful when a 3.5 kW unit would run flat out in afternoon sun.
The Mitsubishi Electric MFZ-KW 4.2kW uses 395 kWh annually for cooling and 709 kWh annually for heating under official GEMS test conditions for Sydney's climate zone. Both cooling and heating modes carry a 2.5 star energy rating. The system achieves an AEER of 3.76 for cooling and an ACOP of 3.76 for heating, indicating the amount of heating or cooling output delivered per unit of electricity consumed.
Your running cost depends on Sydney's current electricity rates applied to these annual energy figures. The GEMS data provides a reliable baseline for comparing this unit's energy consumption against other systems rated under the same Sydney climate zone standard.
