3.5 kWMHI Avanti Plus 3.5kW Split System
The 3.5kW MHI Avanti Plus Split (model SRK35ZSXA-W) is sized for large bedrooms and smaller living rooms. As a guide it suits a typical insulated room of roughly 23 to 28m²; sun exposure and ceiling height move that band. If the space is bigger, has high ceilings or strong afternoon sun, step up to the 5kW.
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 3.5 kW options, or ask about supply and installation.
About $203 a year at the current Sydney median electricity rate: $70 of cooling plus $133 of heating, from the official GEMS test figures.
The MHI Avanti Plus 3.5kW uses 241 kWh annually for cooling and 460 kWh annually for heating, based on official GEMS registration testing for Sydney's climate zone. These figures represent your actual energy consumption under standard conditions and form the basis of running cost estimates shown separately on this page.
The system achieves a 4-star cooling efficiency rating and 3.5-star heating efficiency rating for Sydney. It delivers a rated cooling efficiency of 4.66 AEER and heating efficiency of 4.72 ACOP, using R32 refrigerant. Your actual running costs will depend on your local electricity rate and how often you use heating versus cooling.
