8.5 kWFujitsu Lifestyle 8.5kW Split System
The 8.5kW Fujitsu Lifestyle Split (model ASTG30KMTC) is sized for very large open-plan rooms and light commercial spaces. As a guide, it cools a room of up to about 61 to 71 m². 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. Western sun, poor insulation and high ceilings bring it down. It sits in the upper half of the Fujitsu Lifestyle Split range. If the space is bigger, has high ceilings or strong afternoon sun, step up to the 9.4kW.
Part of the Fujitsu Lifestyle Split range, Fujitsu General'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 8.5 kW options, see every 8kW split system ranked by running cost, or ask about supply and installation.
About $695 a year at the current Sydney median electricity rate: $270 of cooling plus $425 of heating, from the official GEMS test figures.
The Fujitsu Lifestyle 8.5kW uses 814 kWh annually for cooling and 1282 kWh for heating, based on official GEMS testing in Sydney's climate zone. These figures reflect the system's rated efficiency of 3.43 AEER for cooling and 3.82 ACOP for heating. Your actual energy consumption will depend on how often you run the system and your preferred temperature settings.
The system carries a 2.5-star cooling rating and 2-star heating rating under the zoned energy label for Sydney. The exact running cost depends on your electricity rate and usage patterns. Check the current cost estimate displayed separately on this page, which updates with Sydney's electricity rates.
