5 kWPanasonic RZ 5kW Split System
The 5 kW Panasonic RZ Split System cools a room of up to about 36 to 43 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 5 kW options, see every 5kW split system ranked by running cost, or ask about supply and installation.
About $402 a year at the current Sydney median electricity rate: $133 of cooling plus $269 of heating, from the official GEMS test figures.
The Panasonic RZ 5kW uses 402 kWh annually for cooling and 813 kWh for heating, based on official government test data for Sydney's climate zone. These figures show the system's energy consumption under standard conditions and form the basis for your running cost estimate.
