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 5 kW options, or ask about supply and installation.
