6 kWPanasonic RZ 6kW Split System
The 6 kW Panasonic RZ Split System cools a room of up to about 45 to 50 square metres as a guide. That is from Mitsubishi Heavy Industries' sizing chart for an insulated room: the larger figure if it faces north, the smaller if it faces east. Sun exposure, ceiling height and insulation move those figures, 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 6 kW options, or ask about supply and installation.
About $424 a year at the current Sydney median electricity rate: $163 of cooling plus $261 of heating, from the official GEMS test figures.
The Panasonic RZ 6kW uses 491 kWh per year for cooling and 787 kWh per year for heating under official test conditions for Sydney's climate zone. These figures, registered with the Greenhouse and Energy Minimum Standards (GEMS) program, form the basis of your running cost estimate shown separately on this page. Your actual consumption will vary depending on how often you run the system and your temperature settings.
The unit achieves a 3.5-star energy rating for cooling and 3-star rating for heating in Sydney's climate zone. Its rated cooling and heating coefficients of performance (AEER 3.23 and ACOP 3.42) indicate the efficiency at which it converts electricity into cooling and heating output. The system uses R32 refrigerant.
