2.6 kWRinnai PB Series 2.6kW Split System
The 2.6kW Rinnai PB Series Split (model HSNRP26B) is sized for standard bedrooms and small home offices. As a guide it suits a typical insulated room of roughly 17 to 21m²; sun exposure and ceiling height move that band. It is the smallest capacity in the range. If the space is bigger or sun-exposed, step up to the 3.5kW.
The Rinnai PB Series 2.6kW uses 148 kWh per year for cooling and 276 kWh per year for heating under official government testing conditions for Sydney's climate zone. These figures reflect actual energy consumption in typical Sydney weather patterns and form the basis for running cost calculations at current electricity rates.
The system is rated 5.5 stars for cooling efficiency and 3.5 stars for heating efficiency under the Sydney zoned standard. It achieves a cooling efficiency rating (AEER) of 4.98 and a heating efficiency rating (ACOP) of 5.27. The unit uses R32 refrigerant.
