7.1 kWMHI Ciara 7.1kW Split System
The 7.1kW MHI Ciara Split (model DXK24ZTLA-W) is sized for open-plan living and dining areas. As a guide, it cools a room of up to about 51 to 59 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 Ciara Split range. For a smaller, well-insulated room the 6kW will do the job for less power draw.
Part of the MHI Ciara Split range, Mitsubishi Heavy Industries's split system line, in 7 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 7.1 kW options, see every 7kW split system ranked by running cost, or ask about supply and installation.
About $571 a year at the current Sydney median electricity rate: $209 of cooling plus $362 of heating, from the official GEMS test figures.
The MHI Ciara 7.1kW uses 630 kWh annually for cooling and 1092 kWh annually for heating, based on official GEMS testing for Sydney's climate zone. These figures reflect typical usage patterns and allow you to calculate running costs using your current electricity rate. The system carries a 3-star energy rating for cooling and 2.5-star rating for heating under the zoned labelling scheme.
Efficiency is measured by AEER (3.11 for cooling) and ACOP (3.46 for heating). The system uses R32 refrigerant. Your actual energy consumption will vary depending on how often you run cooling or heating, indoor temperature settings, and how well your home is insulated and sealed.
