beams inhouse vacuum wall chasing

B-D-P--

Hi all,
So have the option of DIY kit or installed for the beams vacuum system,

The difference is 1000, and being honest its childs play to install if your competent.

However, the only thing is the pipe is pretty thick, you'll end up consawing through the whole block to chase it.

Surley this would do a lot of damage to the structural integrity of the 2-3 blocks your about to cut in half vertically?

Has anybody done this themselves and have any tips??

This probably isn't helpful in respect to your question but just something to consider. We didn't go for a built in hoover system as apparently it is quite difficult to make airtight? Don't know what you're shooting for but just something to consider if you're as obsessed with air tightness as me!

Hopefully no, they all have rubber seals at each point,, all pipes end back into the central sealed unit, however I'm open to correction from people who have installed the unit.

Just make sure the joint leaving the house has a good A/T but its poured over with screed so should be.

First point. Only cut blocks vertically, never horizontally - or you could have stuff falling down on you.

This doesn't sound like a good thing to retrofit to a concrete / block / brick-built house, unless you mount it on the surface of the wall.

Just asking here but unless the unit vents externally, then I don't see an issue with A/T

Typically the locations are considered st design stage by your architect. At this stage you may be boxing out ducts/ risers.

Best to stay away from structural walls and ideally the air-tightness layer.

Metric Tensor

Worth noting that if your chase is deeper than a certain percentage of the wall you are essentially turning that wall into a wall that is unrestrained at the chase. i.e. it is now no longer continuous at that point. This is important for the walls strength to support vertical loads (i.e. floors) and ability to withstand lateral loading.

Ask your engineer before you go whacking in a big deep chase in the wall. He/she will point you towards the walls that you should stay away from!

This is new build lads,
Yea so if I go for non load bearing walls we should be ok?

No, never meant horizontal, and yea its new build

Your half right,
It will be going to the vacuum unit which is in the garage. Better job if its done correctly.

Not necessarily. It depends on how they are tied in at the ends and tops and if they are providing bracing to other walls.

I put in one of these 10 years ago and now use a dyson!never great, got blocked, a bitch to unblock. IMHO not worth the money or the hassle.

I would look at using timber or metal stud partitions.

Delphinium

I put a beam in a new build in 1991, think one of the earliest in this country as had some trouble finding supplier. It works perfectly to this day and is one of the regrets I have to be selling and downsizing to an existing house, as probably won't be able to retro fit a system. Would not consider building new and not including a beam.

Good to get it half wrong LOL
So plan B, if there is MHVR, put it in utility room and recover the heat

I got mine fitted by a registered installed.

He done a fairly neat job and cut a chase in the wall with a consaw. Probably no worse that some of the chases I have seen by plumbers or electricians over the years.

If you were really worried, could you cut up a couple of lintels and put them over the locations of the outlets?

Actually something i was contemplating...
Just to give more support.
