8 kWHisense J-Series 8kW Split System
The 8kW Hisense J-Series Split (model HAWJ28KR) is sized for open-plan living and dining areas. As a guide, it cools a room of up to about 57 to 67 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 largest capacity in the range.
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 8 kW options, see every 8kW split system ranked by running cost, or ask about supply and installation.
About $608 a year at the current Sydney median electricity rate: $247 of cooling plus $361 of heating, from the official GEMS test figures.
The Hisense J-Series 8kW uses 745 kWh per year for cooling and 1089 kWh per year for heating, based on official GEMS test data for Sydney's climate zone. It carries a 3-star energy rating for cooling and 2.5-star rating for heating under the zoned labelling system. The system achieves an AEER of 3.24 for cooling and an ACOP of 3.24 for heating.
Your running costs depend on how much you use the system and your local electricity rate. The official annual energy consumption figures above allow you to calculate expected costs based on current Sydney rates. The system uses R32 refrigerant.
