7.1 kWMHI Bronte 7.1kW Split System
The 7.1kW MHI Bronte Split (model DXK24ZRA-W) is sized for open-plan living and dining areas. As a guide it suits a typical insulated room of roughly 47 to 57m²; sun exposure and ceiling height move that band. If the space is bigger, has high ceilings or strong afternoon sun, step up to the 8kW.
The MHI Bronte 7.1kW uses 566 kWh annually for cooling and 1011 kWh annually for heating, based on official GEMS testing in Sydney's climate zone. The system achieves a cooling efficiency rating of 3.5 stars and heating efficiency of 2.5 stars under the zoned labelling standard. These figures reflect real-world energy consumption in Sydney conditions and form the basis for calculating your actual running costs.
Efficiency is measured by AEER (cooling) at 3.83 and ACOP (heating) at 3.94. The system uses R32 refrigerant. Your total running cost depends on the balance between heating and cooling use in your home and current Sydney electricity rates, which are shown separately to give you an accurate estimate.
