5 kWPanasonic RZ 5kW Split System
The 5 kW Panasonic RZ Split System suits rooms around 32 to 40 square metres as a guide. Sun exposure, ceiling height and insulation move that band, which is why we confirm sizing before we quote.
Part of the Panasonic RZ Split System range, Panasonic's split system line, in 7 sizes. Running costs below use the Sydney median rate; the Eastern Suburbs and Western Sydney pages cost systems on their own network tariffs. Check the size against your rooms, compare it with other 5 kW options, or ask about supply and installation.
About $351 a year at the current Sydney median electricity rate: $116 of cooling plus $235 of heating, from the official GEMS test figures.
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.
