I fitted a monoblock air/air unit about three months ago, to heat our previously unheated large landing & upstairs corridor. It’s a bit of an experiment to see what the noise was like, what with having all the bits inside.
We’ve just had nearly a week of subzero mornings & evenings - minus 6°C at one point. I’ve programmed the unit to run from 07.00 to 10.00 & 16.00-23.00 i.e. during colder bits of the day. I can report that it still works well during those minus temperatures & the warmer landing means that any unused/unheated bedrooms don’t get as cold as they used to.
The heater is set to 20°C but a more accurate separate thermometer tells me that it shuts down about 18°C, which is plenty for what we want. Clearly I could get more heat out of it.
In brief, yes they do work. Ours is a Klimea 9HP Mini. The jury is out as to whether we’d want the noise in a living room…
Best for installers but I beg to differ for customers, Daikin would be first choice as you can always get spares where Mitsubishi stop making them after a while.
Yes I believe under EU ruling they do but 7 years is not long. By comparrison we obtained a new control circuit board for a 12 year old Daikin without issue but a Mitsubishi unit was kept going by my contractor using his hoard of 2nd hand spares as Mitsubishi refused to make more spares available and that was for a large number of commercial customers. They are building a bit of a reputation for this I am told.
This sort of advice is why being a member of SF is golden - there’s always someone on here who’s “been there, done that!” or has specialist knowledge. Chapeau!
Agreed that’s the kind of detail you can’t get on the internet, so thanks a lot. One surprising thing that we have learnt after living in this house for nearly two years is the difference in outside temperature according to where you are. The west wall is relatively cold in winter and hot in summer the east the opposite. So the position for our first monobloc would be the east wall of our bedroom as noise doesn’t bother me and my OH is hard of hearing.
