What is a Multi-Head Split System?

‘Multi-head’ is the term for a split system with 2 or more indoor units. There is one unit in each room that is able to heat/cool, and one single outdoor unit on the side or at the back of the house. The make/model of multi-head that you choose will depend on how many rooms you need to heat/cool. You can have up to 9 indoor units for each outdoor unit.

How Do Multi-Head Split Systems Compare?

Traditional Split Systems have a matching outdoor unit for every indoor unit; given that every home has multiple rooms, having an outdoor unit for every indoor unit would take up a lot of space and power consumption – that’s where a Multi-Head system comes in.

With a Multi-Head system, you can have 2 or more indoor units connected to 1 outdoor saving you valuable space, and future servicing costs.

How a Multi-Head Split System works compared to a standard Split System:



How Do Multi-Head Split Systems work?

Multi-Head Split Systems use the same technology as normal Split Systems. They work by having half the system (called a condenser) outside the home, and the other half (called the fan coil, or internal unit) inside the home.

When cooling, the warm air from inside the room is taken in by the fan coil and removed, resulting in cool air recirculating back into the house. While reverse cycle allows for the heat pump to run in reverse to provide heating during cold days.
