6 kWRinnai PB Series 6kW Split System
The 6 kW size of the Rinnai PB Series Split cools a room of up to about 45 to 50 square metres as a guide. 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. We confirm sizing from your details and photos, or on a site visit, before quoting.
Part of the Rinnai PB Series Split range, Rinnai's split system line, in 6 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 6 kW options, or ask about supply and installation.
About $428 a year at the current Sydney median electricity rate: $149 of cooling plus $279 of heating, from the official GEMS test figures.
The Rinnai PB Series 6kW uses 449 kWh per year for cooling and 841 kWh per year for heating, based on official GEMS test data for Sydney's climate zone. These are the energy figures from the government energy label and reflect standard test conditions, not measured household usage.
The system carries a 4-star cooling efficiency rating and 2.5-star heating efficiency rating under the zoned label for Sydney. It has a rated AEER of 3.42 for cooling and an ACOP of 3.85 for heating. Running costs depend on your local electricity rate and how often you use heating and cooling.
