3.5 kWMitsubishi Electric MLZ-KP 3.5kW Cassette System
The 3.5 kW MLZ covers rooms of up to about 25 to 29 square metres from a slim linear grille between joists. 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 MLZ-KP One-Way Cassette range, Mitsubishi Electric's cassette system line, in 3 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 $270 a year at the current Sydney median electricity rate: $96 of cooling plus $174 of heating, from the official GEMS test figures.
The Mitsubishi Electric MLZ-KP 3.5kW uses 289 kWh annually for cooling and 525 kWh for heating, based on official GEMS testing in Sydney's climate zone. These figures reflect typical household use patterns and provide a realistic basis for calculating running costs with current electricity rates.
The system achieves a 3-star cooling efficiency rating and 2.5-star heating rating under Sydney conditions. Its rated cooling efficiency (AEER) is 3.80 and heating efficiency (ACOP) is 3.56. The unit operates on R32 refrigerant. Your actual energy consumption will depend on usage patterns, thermostat settings and local conditions.
