6 kWMHI Avanti Plus 6kW Split System
The 6kW MHI Avanti Plus Split (model SRK60ZSXA-W) is sized for large living rooms and small open-plan areas. As a guide, it cools a room of up to about 45 to 50 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. It is the largest capacity in the MHI Avanti Plus Split range. For a smaller, well-insulated room the 5kW will do the job for less power draw.
Part of the MHI AvantiPlus WF 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 6 kW options, or ask about supply and installation.
About $443 a year at the current Sydney median electricity rate: $176 of cooling plus $267 of heating, from the official GEMS test figures.
The MHI Avanti Plus 6kW uses 530 kWh per year for cooling and 807 kWh per year for heating according to official GEMS testing in Sydney's climate zone. These figures represent the system's actual energy consumption under standard test conditions and form the basis for calculating your running costs using current Sydney electricity rates.
The system carries a 3-star energy rating for both cooling and heating in the Sydney zone. It achieves a rated cooling efficiency (AEER) of 3.55 and heating efficiency (ACOP) of 4.09. Your actual running costs will depend on how often you use the system and your local electricity rate.
