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 cools a room of up to about 51 to 59 m². That is from Mitsubishi Heavy Industries' sizing chart for an insulated room: the larger figure if it faces north, the smaller if it faces east. Western sun, poor insulation and high ceilings bring it down. If the space is bigger, has high ceilings or strong afternoon sun, step up to the 8kW.
Part of the MHI Bronte WF1 Split range, Mitsubishi Heavy Industries's split system line, in 5 sizes. Running costs below use the Sydney median rate; the Eastern Suburbs and Western Sydney pages cost systems on their own network tariffs. Check the size against your rooms, compare it with other 7.1 kW options, see every 7kW split system ranked by running cost, or ask about supply and installation.
About $501 a year at the current Sydney median electricity rate: $180 of cooling plus $321 of heating, from the official GEMS test figures.
The MHI Bronte 7.1kW uses 566 kWh annually for cooling and 1011 kWh annually for heating, based on official GEMS test data for Sydney's climate zone. These figures represent standard energy consumption under controlled test conditions and will vary depending on how often you run the system and your temperature settings.
The unit carries a 3.5-star cooling efficiency rating and 2.5-star heating efficiency rating for Sydney's zone. It has a rated cooling efficiency (AEER) of 3.83 and heating efficiency (ACOP) of 3.94. The system uses R32 refrigerant.
