Designed around the room
A multi-split system connects compatible indoor units to one outdoor unit. It can reduce the number of outdoor units, but capacity, pipe routes and simultaneous use need careful design.
Compatible combinationsIndoor units and capacities must form an approved combination with the selected outdoor equipment.
Independent roomsEach indoor unit normally has its own controls, allowing rooms to operate to different settings.
Pipe route planningEvery indoor unit still needs refrigerant pipework and drainage, so routes should be planned early.
Compare alternativesSeparate single systems can offer different cost, efficiency and resilience benefits and should remain part of the comparison.
Survey before selection
A practical survey confirms room heat gain, suitable capacity, indoor and outdoor positions, routes, drainage, electrics and any access or permission concerns. The final recommendation should reflect the property rather than the page category alone.
Website information is a planning guide. Final equipment and installation requirements are confirmed after a survey.
Relevant systems to compare
