7.1 kWPanasonic RZ 7.1kW Split System
The 7.1 kW Panasonic RZ Split System cools a room of up to about 51 to 59 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 7.1 kW options, see every 7kW split system ranked by running cost, or ask about supply and installation.
About $518 a year at the current Sydney median electricity rate: $193 of cooling plus $325 of heating, from the official GEMS test figures.
The Panasonic RZ 7.1kW uses 582 kWh annually for cooling and 982 kWh annually for heating under Sydney's climate conditions, according to official GEMS test data. The unit carries a 3.5-star energy rating for cooling and 2.5-star rating for heating in the zoned label for Sydney. These ratings reflect the system's efficiency relative to other units of the same capacity tested under standardized Australian conditions.
The system achieves a rated cooling efficiency (AEER) of 3.43 and heating efficiency (ACOP) of 3.81. Your actual running costs will depend on usage patterns, thermostat settings and local electricity rates. The system uses R32 refrigerant. Running cost estimates based on your local Sydney rate are shown separately on this page.
