Panasonic Z Series 7.1kW Split System

Model CS-Z71AKRW

The 7.1kW Panasonic Z Series (model CS-Z71AKRW) 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. Like the rest of the Z Series it runs nanoe X air purification around the clock. If the space is bigger, has high ceilings or strong afternoon sun, step up to the 8kW.

Part of the Panasonic Z Series Deluxe Split range, Panasonic's split system line, in 8 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.
