5 kWMHI Ciara 5kW Split System
The 5kW MHI Ciara Split (model DXK18ZTLA-W) is sized for living rooms and master suites. As a guide it suits a typical insulated room of roughly 33 to 40m²; sun exposure and ceiling height move that band. If the space is bigger, has high ceilings or strong afternoon sun, step up to the 6kW.
The MHI Ciara 5kW uses 459 kWh annually for cooling and 766 kWh annually for heating under official GEMS testing for Sydney's climate zone. These figures reflect typical usage patterns in Sydney and form the basis of running cost calculations. The system holds a 3-star energy rating for cooling and 2.5-star rating for heating under the zoned labelling scheme.
Efficiency is measured by AEER (cooling) and ACOP (heating), rated at 3.12 and 3.55 respectively. The system uses R32 refrigerant. Your actual energy consumption will depend on how often you run the unit and the temperatures you set.
