5 kWMHI Avanti 5kW Split System
The 5kW MHI Avanti Split (model SRK50ZSA-W) is sized for living rooms and master suites. As a guide, it cools a room of up to about 36 to 43 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 largest capacity in the MHI Avanti Split range. For a smaller, well-insulated room the 3.5kW will do the job for less power draw.
Part of the MHI Avanti WF1 Split range, Mitsubishi Heavy Industries'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 5 kW options, see every 5kW split system ranked by running cost, or ask about supply and installation.
About $381 a year at the current Sydney median electricity rate: $141 of cooling plus $240 of heating, from the official GEMS test figures.
The MHI Avanti 5kW uses 427 kWh annually for cooling and 724 kWh annually for heating under official GEMS test conditions for Sydney's climate zone. These figures represent the energy consumption you can expect from standard use patterns in that zone. Your actual running costs depend on your local electricity rate, which is calculated separately on this page.
The system holds a 3-star energy rating for cooling and 2.5-star rating for heating under the zoned energy label for Sydney. It achieves an AEER of 3.57 for cooling and an ACOP of 3.86 for heating, indicating the amount of cooling or heating delivered per unit of energy consumed. The unit operates on R32 refrigerant.
