5.4 kWPanasonic Multi 5.4kW Multi-Split System
Three rooms from a single outdoor unit: 5.4 kW rated cooling (1.8 to 7.3 kW range, 7.0 kW heating) and 9.5 kW of connectable capacity. Suits two bedrooms plus a study or small living room.
Part of the Panasonic Multi-Split range, Panasonic's multi-split system line, in 5 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 5.4 kW options, or ask about supply and installation.
About $406 a year at the current Sydney median electricity rate: $133 of cooling plus $273 of heating, from the official GEMS test figures.
The Panasonic Multi 5.4kW uses 401 kWh per year for cooling and 825 kWh per year for heating under standard test conditions in Sydney's climate zone. These figures come from official GEMS registration data and form the basis of your running cost estimate. The system carries a 4-star energy rating for cooling and 3-star rating for heating under the zoned label for Sydney.
Efficiency is measured by AEER for cooling at 4.75 and ACOP for heating at 4.50. The system uses R32 refrigerant. Your actual energy use will depend on how often you run the system, the temperatures you set, and how your home is insulated and sealed.
