2.5 kWMitsubishi Electric MSZ-EF 2.5kW Split System
The 2.5kW Mitsubishi Electric MSZ-EF Designer Split (model MSZ-EF25VG) 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 Mitsubishi Electric MSZ-EF Designer Split range. If the space is bigger, has high ceilings or strong afternoon sun, step up to the 3.5kW.
The Mitsubishi Electric MSZ-EF 2.5kW uses 182 kWh annually for cooling and 390 kWh annually for heating under official GEMS testing in Sydney's climate zone. Cooling efficiency is rated 4 stars, with a rated AEER of 4.60. Heating efficiency is rated 2.5 stars, with a rated ACOP of 4.55. The system uses R32 refrigerant.
Running costs depend on your electricity rate and usage patterns. The annual energy consumption figures above represent the GEMS test cycle for Sydney conditions and will help you calculate expected costs based on current local rates.
