8 kWActronAir Serene 8kW Split System
The 8kW ActronAir Serene Split (model WRE-080DS) is sized for open-plan living and dining areas. As a guide, it cools a room of up to about 57 to 67 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. If the space is bigger or sun-exposed, step up to the 9kW.
Part of the ActronAir Serene Split range, ActronAir's split system line, in 6 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 kW options, see every 8kW split system ranked by running cost, or ask about supply and installation.
About $579 a year at the current Sydney median electricity rate: $205 of cooling plus $374 of heating, from the official GEMS test figures.
The ActronAir Serene 8kW uses 619 kWh annually for cooling and 1130 kWh annually for heating, based on official GEMS test data for Sydney's climate zone.

The system carries a 3.5-star cooling efficiency rating and 2.5-star heating efficiency rating under the zoned energy label for Sydney.
The unit has a rated cooling efficiency (AEER) of 3.37 and heating efficiency (ACOP) of 3.70. It uses R32 refrigerant. Your actual energy consumption will depend on your usage patterns, thermostat settings and home conditions.
