All indoor units require a condensate pipe and the indoor units should also have a knock out on each side to run the flow and return and drainage externally from the wall.
Ah damn, as expected. Edited by emperorburger on Tuesday 11th August 11:11
What’s the best way to run drainage when units are not on external walls in the house. All 3 units will end up in internal walls in the middle of the house .
Regards
As has been mentioned previously, I think you will need a pump for the drainage if running upwards in to the loft space.
Something like this perhaps.

I loved the look of these (Samsung AF9000) - the price terrified me though!!

All condenser units are ground mounted outside in various stages of disguise.
All the external pipe work runs down to ground level within fake down pipes so it just looks like part of the gutter system.
I’ll post some pics when I get a chance.

All of my pipe work was chased in to the walls and run under the respective floors, so the condensate pipes are using gravity. It was easier for me as the house was being refurbished.

That'll need to be fitted next to the unit though, and produce an annoying buzzing noise every now and then. Better to put in a self-priming pump and have that mounted in the loft. Something like a miniblue would do the trick.As has been mentioned previously, I think you will need a pump for the drainage if running upwards in to the loft space.

They are not that loud. I have all three going today and together they sound like a fan from a hot car.
Noise it the most subjective part about AC installation. What one person thinks is 'noisy', may not bother another in the slightest.Personally, I would not like the sound of a hot car fan running when in my garden, and would certainly also hear it in the house. That does sound 'noisy' to me. Maybe the analogy wasnt quite right?
Problem I have when we had AC engineers around to quote, was that we have side access where it would be obvious/logical to install the inverter, but the neighbours are quite close and their lounge window faces the side. So loud fan noises would be quite noticeable i'd imagine in their primary social room.
Just as another data point, we had two quotes last year:
1. 3 rooms, each with its own split system condenser/inverter, each of 2.5KW cooling power. Supply and install price £6800.
2. 3 rooms, 3 condensers but two inverters (two rooms shared one larger inverter), each of 3.5KW cooling power. Supply and install price £7,500
Hardware was Mitsubishi/Daikin.
We are in Kent.

In terms of noise I'd say that they're slightly louder than a tower fan. You would only notice if there's no other background noise IMO.

I would really appreciate your advice
Just seen this thread and thinking about a DIY split system, to cool ist floor bedroom, well insulated, just under 40 cubic metres.
Inside unit can be fitted on exterior wall, maybe run the pipes down the outside of the wall to the outside unit at 1 metre above ground for ease of servicing.
I do not need it to heat the room, only for cooling.
Am I correct that 9000 BTU's would be suitable?
I see adverts for "Inverter" and "heat pump" types, is there a difference and which would be best for me?
We have no neighbours nearby to worry about with any noise but we are light sleepers and need something quiet. We experienced one in the Med with a night setting and we could hardly hear it, wonderful!
Might this be suitable?

The units will be, what, £700 each? So just over £2k for the three; that means they're quoting nearly £5k for installation. Unless there's something significantly complex about your installation, that sounds like they're taking the piss to me. 1. 3 rooms, each with its own split system condenser/inverter, each of 2.5KW cooling power.

For the one room, that'd be fine. I'm sitting in a room of about that size with a 12k BTU unit but it doesn't have to work very hard and it gets far hotter here than in the UK. Obviously a more powerful unit will cool the room down faster when you first turn it on. Etretat said:

All split air-con units have a heat pump, that's just how they work. "Inverter" refers to part of the electrical system within the unit which in turn dictates the type of motor used to drive the compressor. You're probably not interested in the electronics behind it (google will tell you more if you are) but the summary is that "inverter" compressors are quieter and and more efficient than non-inverter units. The compressor is mounted on the outside unit so any difference in volume will be outside the house not inside. The only things which makes a noise inside the house are the fan which pushes the cool air into the room (which just sounds like a fan) and the condensation pump if you need to route the condensed water upwards to get it out of the house.

Word of caution - these are captured by permitted development planning permission rules. You’re only allowed 1 external unit and there are rules about it being more than 1m or something from the property boundary or flat roof edge. If you get more than 1 external unit or want it at the boundary you technically need planning permission or your neighbours can object.
Some LAs have an exemption, but in general AFAIK you are not allowed *any* without planning permission. A few air conditioning websites mention the above exemption, however it is for air source heat pump microgeneration and not relevant to air conditioning:https://www.planningportal.co.uk/info/200130/commo...

No idea what the underlying prices are. But both entirely different companies quoting the same price. Everything is a ripoff in the SouthEast though innit?kryten22uk said:

A mobile A/C would be much better, or perhaps one of the indoor mounted units that just need a couple of cores through the wall - I've never tried one of those, but presume they are basically the guts of a portable in a smaller package, and wall mounted.

Thank you. I think what I've been looking at is some sort of hybrid of a proper air con and one of these. There are a couple of companies marketing them as being suitable for conservation areas, and conversions where it's not possible to install an outside condenser unit.A mobile A/C would be much better, or perhaps one of the indoor mounted units that just need a couple of cores through the wall - I've never tried one of those, but presume they are basically the guts of a portable in a smaller package, and wall mounted.
The marketing states the water cooled unit can be placed in a utility area or even under a kitchen sink, totally internal to the property.
It's very expensive, but it could be a good solution, if it would actually work?

I don't think someone would dare quote a northerner £21k to paint their (not massive) house for example
