2.5 kWMitsubishi Electric SLZ-M 2.5kW Cassette System
The 2.5 kW compact cassette suits offices and rooms around 17 to 20 square metres with a flush, furniture-free ceiling finish.
The Mitsubishi Electric SLZ-M 2.5kW uses 224 kWh annually for cooling and 400 kWh annually for heating, based on official GEMS testing for Sydney's climate zone. These figures reflect typical usage patterns in Sydney and allow you to calculate running costs against current local electricity rates. The system carries a 2.5-star energy rating for both cooling and heating under the zoned labelling scheme.
The unit operates at a rated cooling efficiency (AEER) of 3.93 and heating efficiency (ACOP) of 3.76. It uses R32 refrigerant. Running costs depend on your actual usage, local electricity tariffs and how you operate the system, but the official annual energy consumption figures provide a reliable basis for comparison.
