17 kWRinnai D Series Ducted 17kW Ducted System
The 17kW Rinnai D Series Ducted (model DINLR17Z72) is sized for larger single-storey or compact two-storey homes. As a guide it covers roughly 113 to 136m² of conditioned floor area, depending on zoning, insulation and ceiling height. For a larger floor plan, the 20kW is the next step up.
The Rinnai D Series Ducted 17kW carries a 4-star cooling rating and a 2-star heating rating on the zoned energy label for Sydney's climate zone. Based on official government test data, it uses 1215 kWh annually for cooling and 2412 kWh for heating. At the median Sydney residential electricity rate of 34.7 cents per kWh as of June 2026, that works out to roughly $422 for cooling, $837 for heating, and $1259 combined across a full year.
The system's rated AEER of 3.28 and ACOP of 3.78 indicate how much cooling and heating output it delivers per unit of electricity consumed. Cooling efficiency is the stronger performer of the two, which is typical for ducted systems of this capacity. These figures give a reliable basis for comparing running costs with other systems of a similar size.
