The 7 kW size of the Rinnai PB Series Split cools a room of up to about 51 to 58 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.

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 7 kW options, see every 7kW split system ranked by running cost, or ask about supply and installation.
