2.5 kWHisense J-Series 2.5kW Split System
The 2.5kW Hisense J-Series Split (model HAWJ9KR) is sized for standard bedrooms and small home offices. As a guide, it cools a room of up to about 18 to 21 m². That is from Mitsubishi Heavy Industries' sizing chart for an insulated room: the larger figure if it faces north, the smaller if it faces east. Western sun, poor insulation and high ceilings bring it down. It is the smallest capacity in the range. If the space is bigger or sun-exposed, step up to the 3.5kW.
Part of the Hisense J-Series Split range, Hisense's split system line, in 5 sizes. Running costs below use the Sydney median rate; the Eastern Suburbs and Western Sydney pages cost systems on their own network tariffs. Check the size against your rooms, compare it with other 2.5 kW options, see every 2.5kW split system ranked by running cost, or ask about supply and installation.
About $182 a year at the current Sydney median electricity rate: $59 of cooling plus $123 of heating, from the official GEMS test figures.
The Hisense J-Series 2.5kW has an official annual cooling energy use of 177 kWh and annual heating energy use of 371 kWh, based on government GEMS registration test data for Sydney's climate zone. It carries a 4-star energy rating for cooling and a 3-star rating for heating under the zoned label system.
The system achieves a rated AEER of 3.99 for cooling and ACOP of 4.45 for heating, indicating the amount of cooling or heating output delivered per unit of electricity consumed. It uses R32 refrigerant. Your actual running costs depend on how often you run the system and current Sydney electricity rates.
