8 kWMHI Bronte 8kW Split System
The 8kW MHI Bronte Split (model DXK28ZRA-W) is sized for open-plan living and dining areas. As a guide it suits a typical insulated room of roughly 53 to 64m²; sun exposure and ceiling height move that band. If the space is bigger, has high ceilings or strong afternoon sun, step up to the 9.5kW.
The MHI Bronte 8kW uses 666 kWh annually for cooling and 1159 kWh annually for heating under official GEMS testing conditions for Sydney's climate zone. These figures reflect your actual energy consumption for estimating running costs. The system carries a 3.5-star cooling efficiency rating and 2.5-star heating efficiency rating for Sydney conditions.
The MHI Bronte 8kW delivers a rated cooling efficiency (AEER) of 3.58 and heating efficiency (ACOP) of 3.73. These metrics indicate how much cooling or heating output you receive per kilowatt of electricity consumed. The system uses R32 refrigerant, a low-GWP fluid that meets current environmental standards.
