Refurbishing a flat, and I'm told that I'm not allowed external units, and it appears even vents are a no no, though I'm still seeking clarification on this.

I've found one lot that claim to be able to do the work inside, plumbing in the condensation pipes to discharge through the natural waste pipes of the property.

Just wondering if anyone has come across anything like this, or had any AC fitted, and what to watch for, advice etc.


Cheers!

Noise? What happens to the heat? Don't really understand how such a system could work?

Just got off the phone with them, seems interesting.

Zero heat generated, not sure about noise yet. However have been told it can be totally enclosed, airing cupboard, box, under the sink etc. Not cheap at about £4650+ Vat (per room!)

Its watercooled, so I guess the heat is pushed down the drain

Obviously a considerable premium to units where you just have 2 vent holes in the wall, which go for about £1200

I spoke to those guys a while ago as i had a similar issue. Think the guy was called julian? They can do a cheaper job that involves making 2 holes in wall. Speak to a director of your buildings management co and see if they're open to it.

So is it using mains cold water to cool the evap which then goes down the drain? If so Web site doesn't mention how much water it consumes to do that.

Yeah I wondered that myself, but since I'm not on a meter I'm not that bothered to be honest

Those "fully internal" systems seem to break some fairly fundamental laws of physics? Unless it's constantly using mains water, which sounds dubious.

Indeed, it does appear to be a continuous water user. (Instead of having warm air blowing out of the condenser, it is pouring warm water down the drain all the time) I can see how it would be done - when water temp in the system reaches a certain temp / gas pressure, an outlet valve is opened up, like the thermostat in your car.

Incredibly wasteful of water!

I say very wasteful, but then again, it is indeed a neat way of doing it! There would be no way of convincing them to put a usual air condenser up in the loft or something?

Andehh

No way of using a standalone system, sat next to a window with the vent out of it? (obvs with a plastic try to block the rest of the 'open window'. Cost a fraction less then what you mention, and for the sake of £2500+ per room, gotta be worth moving a coffee table to make it work for 5 months of the year?

What about one of those US style window mounted units?

No loft, it's a 3rd floor flat and a block of 6 floors.

Honestly, a stand alone unit by the window is what I use. But with tilt Windows it's not that helpful since air gets in at the bottom and top meaning you have to have the curtains closed all the time.

Top question on my list is going to be how much water they use!

Right, fresh from chatting to them.

I asked about water usage, he said they've recently fitted a water meter to someone's unit, who works from home and so its on a good amount of time. So far its showing water usage of about 200l a day. 1 cubic meter of water (1000l) costs about £2.50 so water wise its not particularly expensive. Additionally it uses less electricity than the split units since there isn't a big fan as a heat exchanger.

Noise wise he said very slight hum like a fridge, but not something you'd hear when going about your business. It produces no heat so can be boxed in. The units do need water, waste and electricity to them, but can be stuck in cupboards, under the sink etc.

Fairly sure I'm going to stick one unit in.

£150 a year in water!? Plus electricity
That's really wasteful. and the unit is mega bucks

I think you should look more into whether it is possible to make small holes in the wall to get their other system. I'm always careful about buying bespoke, low volume stuff, it can't be that well developed or tested, the whole thing sounds like a stinker to me
