The Rinnai Inverter Multi Split System is the simplest way to heat or cool up to five individual rooms with only one outdoor unit. Traditionally, five rooms would require five indoor units and five outdoor units. This uses up precious outdoor space and creates an obtrusive appearance to your home. Rinnai Multi Split Systems not only provide individual control of comfort levels in each room, but saves you money on running costs by either only heating or cooling individual rooms as required.

Rinnai Inverter Multi Split Systems offer 3 different indoor unit types (Wall Mounted, Slim Ducted, and Compact Cassette) that can be used in a multitude of combinations. After selecting up to 5 indoor unit types, these are then paired with an outdoor unit (4 units to choose from) with capacities ranging from 7.1kW up to 13.kW. With a variety of unit types and capacities available, Rinnai has a system configuration to suit virtually any requirement.
