The Panasonic RZ 5kW uses 402 kWh annually for cooling and 813 kWh for heating under official GEMS test conditions for Sydney's climate zone. These figures reflect real-world performance in typical Sydney conditions and form the basis for the running cost estimate shown separately on this page, which updates with current electricity rates.
The system holds a 3.5-star cooling efficiency rating and 2.5-star heating efficiency rating for Sydney. It delivers a rated cooling efficiency (AEER) of 3.29 and heating efficiency (ACOP) of 3.47. The unit uses R32 refrigerant. Your actual energy consumption will vary depending on how often you run the system and your temperature settings.
