3.3 kWMHI Ciara 3.3kW Split System
The 3.5kW MHI Ciara Split (model DXK12ZTLA-W) is sized for large bedrooms and smaller living rooms. As a guide it suits a typical insulated room of roughly 23 to 28m²; sun exposure and ceiling height move that band. If the space is bigger, has high ceilings or strong afternoon sun, step up to the 5kW.
Part of the MHI Ciara Split range, Mitsubishi Heavy Industries'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 3.3 kW options, or ask about supply and installation.
About $213 a year at the current Sydney median electricity rate: $82 of cooling plus $131 of heating, from the official GEMS test figures.
The MHI Ciara 3.3kW uses 285 kWh per year for cooling and 452 kWh per year for heating, based on official GEMS testing for Sydney's climate zone. Both functions carry a 3-star energy rating under the zoned labelling system, indicating moderate efficiency for this climate. The system achieves a cooling efficiency rating (AEER) of 3.60 and a heating efficiency rating (ACOP) of 4.14.
Your actual running costs depend on your local electricity rate and how often you run the unit. The verified annual energy consumption figures above let you calculate expected costs using your current Sydney rate. The system uses R32 refrigerant.
