3.5 kWMitsubishi Electric SLZ-M 3.5kW Cassette System
The 3.5 kW SLZ covers up to about 25 to 29 square metres, the common pick for home offices and small retail fit-outs. 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.
Part of the Mitsubishi Electric SLZ-M Compact Cassette range, Mitsubishi Electric's cassette 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 3.5 kW options, or ask about supply and installation.
About $282 a year at the current Sydney median electricity rate: $106 of cooling plus $176 of heating, from the official GEMS test figures.
The Mitsubishi Electric SLZ-M 3.5kW uses 320 kWh annually for cooling and 530 kWh for heating under official GEMS test conditions for Sydney's climate zone. These figures represent your system's actual energy consumption in typical use, so your running costs scale directly with local electricity rates.
The unit carries 2.5-star energy ratings for both cooling and heating in Sydney's climate zone. It achieves a rated cooling efficiency (AEER) of 3.68 and heating efficiency (ACOP) of 3.74. The system uses R32 refrigerant.
