2.5 kWMitsubishi Electric MSZ-LN 2.5kW Split System
The 2.5kW Mitsubishi Electric MSZ-LN Premium Split (model MSZ-LN25VG) is sized for standard bedrooms and small home offices. As a guide, it cools a room of up to about 18 to 21 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 smallest capacity in the Mitsubishi Electric MSZ-LN Premium Split range. If the space is bigger, has high ceilings or strong afternoon sun, step up to the 3.5kW.
Part of the Mitsubishi Electric MSZ-LN Premium Split range, Mitsubishi Electric's split system line, in 4 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 2.5 kW options, see every 2.5kW split system ranked by running cost, or ask about supply and installation.
About $163 a year at the current Sydney median electricity rate: $53 of cooling plus $110 of heating, from the official GEMS test figures.
The Mitsubishi Electric MSZ-LN 2.5kW uses 160 kWh annually for cooling and 333 kWh annually for heating, based on official GEMS testing for Sydney's climate zone. These figures reflect typical year-round use and form the basis for running cost estimates. The system achieves a cooling efficiency rating of 4.5 stars and heating efficiency of 3.5 stars under the same testing standard.
The unit delivers a rated cooling efficiency (AEER) of 5.07 and heating efficiency (ACOP) of 5.30. It uses R32 refrigerant. Your actual running costs depend on your usage patterns and your electricity rate, but the official annual energy consumption figures above provide a reliable baseline for comparison with other systems.
