Multi Split Heat Pumps for Rotorua Homes
One outdoor unit runs heads in several rooms, so you heat the whole house without a fan hanging off every wall. Handy on the smaller valley and lakeside sections around town.
A multi split heat pump runs two or more indoor units off a single outdoor compressor. It heats several rooms at once, suits Rotorua homes with lots of small rooms and tight sections, and keeps just one tidy box outside instead of one per room.
How a multi split system actually works
One outdoor unit sits against the house. Refrigerant pipes run from it up into the roof or wall cavity and feed each indoor head. You set every room to its own temperature from its own remote, so the kids' bedroom can sit cooler while the lounge runs warm.
That's the main difference from a single split, which is one indoor head to one outdoor unit. If you're weighing up your options, our rundown of the types of heat pump lays out where a multi split fits against the alternatives.
When a multi split suits a Rotorua home
The mid-century bungalows around Glenholme and Springfield are full of small single-glazed rooms. Bolting a separate outdoor unit to each one gets ugly fast, and on a tight valley or lakeside section there often isn't room. A multi split keeps it to one box in a sensible spot.
Newer sealed builds in Lynmore and Ngongotaha hold heat well, so a multi split with a couple of well-placed heads can carry most of the house. If you'd rather hide the indoor units, ceiling cassette heat pumps tuck into the ceiling, and floor console heat pumps sit low like an old heater, which older folks tend to prefer.
For a home you want heated as one connected space, a ducted heat pump system in Rotorua is worth a look too, though it costs more and needs the roof space.
Holding heat through Volcanic Plateau frosts
Our winter mornings bite. A multi split needs enough grunt in the outdoor unit to run all its heads flat out on a frosty start, not just one at a time. Undersize it and the whole house feels gutless when you need it most.
We sort the numbers before we quote. You can get a rough idea yourself with our heat pump sizing calculator, and we back a lot of Rotorua installs with Mitsubishi Electric heat pumps because their cold-climate models hold output when the frost sets in and the lake damp lingers.
Getting the install and pricing right
Pipe runs, head placement and where the outdoor unit lands all change how well a multi split performs and what it costs to fit. We talk it through on-site before anything goes up the wall. Have a read of how we handle heat pump installation in Rotorua so you know what to expect on the day.
Multi splits carry a higher upfront number than a single split, mostly in the pipework and the larger outdoor unit. Our page on heat pump installation cost breaks down what drives the price so there are no surprises.

Multi split heat pump questions
How many indoor units can one multi split system run?
It depends on the outdoor unit, but most run between two and five indoor heads. The bigger the unit, the more heads and the more total heating it can carry. We match the outdoor size to how many rooms you're running and how cold they get, so nothing runs short on a frosty morning.
Is a multi split cheaper than separate heat pumps in each room?
Not usually on the hardware alone. A multi split's outdoor unit and pipework cost more than a single split, so if you only want one or two rooms, separate splits can work out cheaper. Once you're heating three or more rooms, a multi split often makes more sense on install tidiness and having just one unit outside.
Can a multi split heat both a bedroom and living area at once?
Yes. Each indoor head runs to its own setting, so you can heat the lounge and a bedroom at the same time at different temperatures. Just remember all the heads share one outdoor unit, so if you run several flat out at once, each gets a portion of the total output. That's why sizing it right matters.
