The 12.5kW Daikin Slimline Ducted is sized for typical three-bedroom single-storey homes. As a guide it covers roughly 83 to 100m² of conditioned floor area, depending on zoning, insulation and ceiling height. It sits in the upper half of the Daikin Slimline Ducted range. For more bedrooms or a larger floor plan, the 14kW is the next step up.
The Daikin Slimline Ducted 12.5kW uses 1104 kWh annually for cooling and 1853 kWh for heating under Sydney climate conditions, based on official GEMS testing. These figures let you 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 in Sydney's climate zone, indicating moderate efficiency for a ducted unit of this capacity.
The Daikin achieves a rated cooling efficiency (AEER) of 3.36 and heating efficiency (ACOP) of 3.82. It uses R32 refrigerant. Your actual energy consumption will vary depending on how often you run the system, your thermostat settings, and how well your home is insulated and sealed.
