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 uses 1215 kWh annually for cooling and 2412 kWh annually for heating under official GEMS testing in Sydney's climate zone. These figures reflect actual measured performance and allow you to calculate running costs using your electricity rate. The system achieves a cooling efficiency rating of 4 stars and a heating efficiency rating of 2 stars.
Cooling efficiency is measured by the AEER of 3.28, while heating efficiency is indicated by an ACOP of 3.78. The higher these coefficients, the more efficiently the system converts energy into heating or cooling. Your total annual energy consumption will depend on how much you run the system for heating versus cooling across the year.
