3.5 kWPanasonic Z Series 3.5kW Split System
The 3.5kW Panasonic Z Series (model CS-Z35AKRW) is sized for large bedrooms and smaller living rooms. As a guide it suits a typical insulated room of roughly 23 to 28m²; 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 4.2kW.
The Panasonic Z Series 3.5kW uses 240 kWh annually for cooling and 452 kWh for heating under official GEMS testing in Sydney's climate zone. These figures represent your actual expected energy consumption in Sydney conditions. The system achieves a cooling efficiency rating of 4.5 stars and a heating efficiency rating of 3 stars under the zoned labelling scheme.
The unit's rated cooling efficiency (AEER) is 4.22 and its heating efficiency (ACOP) is 4.55. Your running costs depend on your local electricity rate and usage patterns. The system uses R32 refrigerant.
