2.5 kWMHI Ciara 2.5kW Split System
The 2.5kW MHI Ciara Split (model DXK09ZTLA-W) is sized for standard bedrooms and small home offices. As a guide it suits a typical insulated room of roughly 17 to 20m²; sun exposure and ceiling height move that band. If the space is bigger, has high ceilings or strong afternoon sun, step up to the 3.5kW.
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 2.5 kW options, or ask about supply and installation.
About $159 a year at the current Sydney median electricity rate: $58 of cooling plus $101 of heating, from the official GEMS test figures.
The MHI Ciara 2.5kW uses 201 kWh annually for cooling and 350 kWh for heating, based on official GEMS testing in Sydney's climate zone. These figures reflect actual energy consumption under standard test conditions and form the basis of your running cost estimate. The system holds a 3-star energy rating for both cooling and heating, indicating moderate efficiency within the zoned label system for Sydney.
The unit's rated efficiency is 4.18 AEER for cooling and 4.43 ACOP for heating. This means the system delivers around 4 units of cooling or heating energy for every unit of electrical energy consumed. The MHI Ciara 2.5kW uses R32 refrigerant, a lower global warming potential alternative to older refrigerants.
