7.1 kWPanasonic Z Series 7.1kW Split System
The 7.1kW Panasonic Z Series (model CS-Z71AKRW) is sized for open-plan living and dining areas. As a guide it suits a typical insulated room of roughly 47 to 57m²; sun exposure and ceiling height move that band. 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, or ask about supply and installation.
About $452 a year at the current Sydney median electricity rate: $168 of cooling plus $284 of heating, from the official GEMS test figures.
