2.5 kWDaikin Zena 2.5kW Split System
The 2.5kW Daikin Zena Split System is sized for standard bedrooms and small home offices. As a guide, it cools a room of up to about 18 to 21 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 is the smallest capacity in the Daikin Zena Split System range. If the space is bigger, has high ceilings or strong afternoon sun, step up to the 3.5kW.
Part of the Daikin Zena Split System range, Daikin's split system line, in 4 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 2.5 kW options, see every 2.5kW split system ranked by running cost, or ask about supply and installation.
About $187 a year at the current Sydney median electricity rate: $63 of cooling plus $124 of heating, from the official GEMS test figures.
The Daikin Zena 2.5kW is rated 3.5 stars for cooling and 3 stars for heating under the Australian government's GEMS testing standard for Sydney's climate zone. Official annual energy consumption is 189 kWh for cooling and 375 kWh for heating. The system achieves a rated cooling efficiency (AEER) of 5.03 and heating efficiency (ACOP) of 4.80.
Running costs depend on your local electricity rate and how often you use heating versus cooling. The official test figures above show typical annual energy draw in Sydney conditions, which you can multiply by your current electricity rate to estimate annual running costs for your household.
