3.5 kWDaikin Alira X 3.5kW Split System
The 3.5kW Daikin Alira X Split System is sized for large bedrooms and smaller living rooms. As a guide, it cools a room of up to about 25 to 29 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 lower half of the Daikin Alira X Split System range. If the space is bigger, has high ceilings or strong afternoon sun, step up to the 4.6kW.
Part of the Daikin Alira X Split System range, Daikin'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 3.5 kW options, see every 3.5kW split system ranked by running cost, or ask about supply and installation.
About $197 a year at the current Sydney median electricity rate: $71 of cooling plus $126 of heating, from the official GEMS test figures.
The Daikin Alira X 3.5kW uses 215 kWh per year for cooling and 380 kWh per year for heating, based on official government test data for Sydney's climate zone. The system holds a 5-star energy rating for cooling and 3.5-star rating for heating under the zoned energy label. These ratings reflect the unit's efficiency during standardised testing conditions.
The Daikin Alira X 3.5kW achieves a rated cooling efficiency (AEER) of 4.35 and heating efficiency (ACOP) of 4.84. The unit uses R32 refrigerant. Your actual running costs will depend on how often you run the system and your local electricity rate.
