I’ve had a browse through several other posts on the forum and see there are different views on multi-split vs single heatpumps vs ducted, so I’m hoping for some sage advice on my particular situation. We have a small 1950s home in Chch, currently heated by a heat pump in the open plan lounge/dining kitchen, with nobo panel heaters in the bedrooms. Our real issue is in summer, with norwest days in Chch where it can get to 31 degrees and make sleeping impossible. Our daughter has a medical condition that makes a good night’s sleep essential, so we’re looking at options for cooling. We currently have ceiling fans but they don’t really do what we need. I was initially thinking a ducted system, but then thought perhaps that was overkill, price wise, so thought a 3 room multi split might work just for the bedrooms, so long as we could tuck the outside unit around the side of the house. But then I read some of the posts on here about how multi-split systems aren’t great for various reasons, so I’m scratching my head. Any suggestions? House is double glazed and insulated.
I am not a fan of split units being used in bedrooms unless there's a strong need for AC in the summer. The reason? You've got a unit that runs with a fan and quite often the fan gets to the point where the air circulation feels cold (it isn't it's just the sensation of breeze).
As Timmay has alluded to over all of these years it's a process to figure out what works best. I would probably start with getting an outdoor unit that can have multi units added to, but start with one or two units in main areas only. I was very surprised how well our single 7kWh unit was able to push heat throughout the house.
My question was about bedroom cooling, we already have a heat pump for the living areas.
You need a multi-split, that will be perfect for your requirements,
Don't waste time on ducted, they are nowhere near effective enough specifically for cooling.
With a multi-split, you are only cooling the air required in the room and only to the level required. So they are extremely cost effective. Your child with the medical issue will love you for it!
My child & I can finally sleep better at night with a multi-split.
