6.3 kWMHI Ciara 6.3kW Split System
The 6kW MHI Ciara Split (model DXK21ZTLA-W) is sized for large living rooms and small open-plan areas. As a guide it suits a typical insulated room of roughly 40 to 48m²; sun exposure and ceiling height move that band. If the space is bigger, has high ceilings or strong afternoon sun, step up to the 7.1kW.
The MHI Ciara 6.3kW uses 516 kWh per year for cooling and 946 kWh per year for heating under official GEMS testing conditions for Sydney's climate zone. These figures reflect typical annual energy consumption and form the basis of the running cost estimate shown separately on this page, which updates with current Sydney electricity rates.
The system carries a 3.5-star cooling efficiency rating and 2.5-star heating efficiency rating for Sydney. Its rated cooling efficiency (AEER) is 3.40 and heating efficiency (ACOP) is 3.51. It uses R32 refrigerant.
