9.5 kWMHI Bronte 9.5kW Split System
The 9.5kW MHI Bronte Split (model DXK33ZRA-W) is sized for very large open-plan rooms and light commercial spaces. As a guide it suits a typical insulated room of roughly 63 to 76m²; sun exposure and ceiling height move that band. If the space is bigger, has high ceilings or strong afternoon sun, step up to the 10kW.
The MHI Bronte 9.5kW uses 773 kWh annually for cooling and 1281 kWh annually for heating under official GEMS testing in Sydney's climate zone. These figures reflect the system's actual energy consumption in typical Sydney conditions and form the basis for running cost calculations using your local electricity rate.
The system carries a 3.5-star cooling efficiency rating and 2.5-star heating rating for Sydney. It achieves a rated cooling efficiency of 3.69 AEER and heating efficiency of 3.88 ACOP. The unit uses R32 refrigerant and is sized to deliver 9.5 kW of cooling capacity.
