Had an email this morning to say the external unit has arrived and they are installing on Thursday/Friday.

They still don’t have the external unit for my garage/home gym yet.

My external Bosch unit has to be replaced with two smaller Bosch units to bring it into compliance with MCS020a. Ordered 2 weeks ago, original ETA was September, now December. Considering had I ordered them a month earlier I'd have had them next day, the spike in demand is insane.

Ah that sucks! I assume your current unit is too loud and fails noise compliance? I had the same concern with my 10kW external unit but the neighbours nearest window is over 7m away across the shared drive and also a bathroom window.

I think my order was played 23/06 so not too bad at 5 weeks. I didn’t hang about during the first heat wave getting booked in.

Yeah, unfortunately just slightly over. Had it been installed earlier this year it would have been compliant with the older standard (MCS020). Considered retrospective planning permission but that particular neighbour is hostile so it was only going to go one way. In reality it is actually quite quiet and certainly not at the threshold of being a nuisance, but 'thems the rules'. So I'm replacing it to avoid a planning enforcement, although the long lead time for the new units might lead to one anyway in the meantime.

Anyone got experience of ducted AC?

We're considering AC over the next year or so, and we like the idea of ducted AC, as it means you don't have a bulky unit mounted on the wall. Anyone had them installed & can give their thoughts? Worth it over standard units (I'm assuming it'll be more expensive)? Any particular thoughts to consider?
 
Finally got the split AC I ordered finished today (to be fair wasn't started until weekend just gone as I had other jobs on the list that were apparently priority)

Oh the joy of coming in from outside and immediately feeling the difference

Interesting that its quoted as 800w in cooling mode but its been up as high as almost 1300w

Its cooling the room from 31 (it said) to target of 24 though so maybe once its getting closer to 24 it will drop energy
Door is open also so its cooling into the landing as well

Nicer I guess but I'd bet it's a lot more expensive due to the additional install complications as you'd have to have ducting in your ceiling cavities so quite a major job.

The condensing unit will still have to sit somewhere outside.

DIY?
 
Is the 800w a nominal figure? As in, if the rooms 30c and you tell it to bring it down to 24 it's gonna be working it's **** off till it gets to the target temp, then it will calm down and just maintain 24c?

That’s exactly what it’ll do. It’ll work harder in this weather. 7kw used already today. Worth every penny.

I guess so, its a little vague although the plate on the side says that and around 1100w in heating mode, its probably some kind of mid point thing.

The fan was on full blast and I turned it down to low and it dropped from 1200ish (where it settled) to about 1050
Mrs was complaining she was cold after 45 mins or so in there, not something I have heard since probably March time

You can feel the cold air going down the stairs so in effect its trying to cool most of the house I think (4 bed detached) so think its probably going to stay at that level for now
I mean I turned it on about 4pm when most of the house was probably in the 30s, the main bedroom said 31 but my office next to it said 35.5 so its warm.
Closed all the windows just the cat flap open downstairs and the cats room ensuite extractor is on as thats where their litter tray is!
 
Might be better off keeping internal doors closed, then once that room hits you target temp (let's say 24 for arguments sake) then it should start using a lot less power as it's just maintaining a temp rather than cooling a hot room.

If it's upstairs, Then as you say, it will be working harder for longer as the cold air will be going downstairs.

Much like a central heating thermostat, you should just set your desired room temp rather than adjusting it constantly.

I have several split systems in my Spanish house and my bedroom I just set to 24c at night.. Any colder and I wake up freezing in the middle of the night so it's just a waste of electricity if you keep over compensating.
 
Yeah and if it's upstairs and all the internal doors are open.. That cold air is going to go straight downstairs meaning the unit is going to be working harder, for longer.
