2.5 kWMHI Avanti Plus 2.5kW Split System
The 2.5kW MHI Avanti Plus Split (model SRK25ZSXA-W) is sized for standard bedrooms and small home offices. As a guide it suits a typical insulated room of roughly 17 to 20m²; sun exposure and ceiling height move that band. It is the smallest capacity in the MHI Avanti Plus Split range. If the space is bigger, has high ceilings or strong afternoon sun, step up to the 3.5kW.
The MHI Avanti Plus 2.5kW uses 166 kWh per year for cooling and 320 kWh per year for heating under official government testing for Sydney's climate zone. These figures reflect typical annual operation and form the basis for running cost estimates. The system achieves a 4.5-star cooling efficiency rating and 4-star heating rating on the zoned label for Sydney.
The MHI Avanti Plus 2.5kW is rated at 5.54 AEER for cooling and 5.32 ACOP for heating, meaning it delivers substantially more heating or cooling energy than the electrical energy it consumes. The unit uses R32 refrigerant and is designed to minimise energy waste during operation across Sydney's climate conditions.
