Air-to-Air · Multi-split

One outdoor system. A choice for every room.

Plan independently controlled room units, mix the ranges that suit each space, and see only indoor and outdoor combinations listed by the manufacturer.

Each room has its own controller and set temperature. Connected rooms share one outdoor system and operate in the same overall heating or cooling mode.

What multi-split means

Fewer outdoor units, without making every room the same.

A multi-split connects two or more indoor units to one outdoor heat pump. Each room can have a different compatible indoor range and its own temperature setting. The outdoor unit shares its available capacity across rooms, so the exact size combination matters.

Choose by room

Prioritise design in a living room, everyday features in bedrooms, or a different compatible mix.

Share the outdoor system

Reduce the number of outdoor units and plan spare connections only where the published combination permits.

Control rooms separately

Set rooms independently, while all connected units remain in the same overall heating or cooling mode.

Advantages

  • One outdoor unit can serve several rooms.
  • Compatible indoor ranges and finishes can be mixed by room.
  • Rooms retain separate controllers and set temperatures.
  • A phased installation can be discussed where capacity and ports allow.

Trade-offs

  • Connected rooms cannot heat and cool at the same time.
  • Available outdoor capacity is shared when several rooms run together.
  • Pipe routes, level differences and condensate need coordinated design.
  • A spare port does not by itself guarantee capacity for a future room.

Standard multi-split or Multi+

Hot water changes the system, not just the wording.

Rooms only

Standard multi-split

Daikin or Mitsubishi Electric outdoor equipment serving compatible room units for heating, cooling and dry mode.

Two to six rooms on one outdoor unit, depending on the selected range and exact combination.

Rooms and hot water

Daikin Multi+

A distinct Daikin outdoor system that serves compatible room units and a 120 or 230 litre domestic hot-water tank.

Up to three or four room units depending on the outdoor model. It is not a conventional multi-split with a tank added later.

Configure your home

Start with rooms, not model numbers.

What should the outdoor system provide?

Choose the journey first. Multi+ is a separate hot-water system, not an optional accessory for standard multi-split.
