Any plumbers out there?

<font color='#0000FF'>Any of the YD lot know the in's and out's of domestic heating arrangements pertaining to the siting of combination (combi) boilers?

As me missus wants it shifted oot of her kitchen.

Or anyone (Dr. Stevil territory here) know of any useful fora where said information can be found?

Drifty,
&nbsp; &nbsp; &nbsp; &nbsp; It's all British Standards stuff. I've got the full book of rules and regs, but it's &quot;far&quot; too much to start typing out. Even at that, there's too much IIRC to photocopy and send down to you. There's standard rules and then the manufacturer of the individual boiler will have there own seperate instructions. You can &quot;buy&quot; the BS stuff from their website or you can go to your local reference library, mine is the Mitchell in town, and look it up there. It's fairly easily findable stuff and if you've got a modicum of technical know-how you should be able to understand it. Obviously though you need a CORGI registered guy to fit it. I can certainly tell you a plumber &quot;NOT&quot; to go to and if you have any direct questions I'll look them up for you.

Howard &nbsp;would probably know but he's away for a couple of days, maybe a PM will do it. We moved ours out of the kitchen when we re-did the CH with a condensing boiler intoi the garage, well ventilated and accesable, no problem at all. The garage is integral to the house but has two doors, one for the motor, and one to the rear garden/side of house.

<font color='#0000FF'>Cheers guys.

The crux of the question is what is the maximum permissible horizontal flue length for a gas combi boiler and what constraints are there with regard to internal positioning?

It's amazing what you discover people have done in a house you've bought when you start looking around......

Oh, and Building Warrants from WLC are not worth the paper they are printed on.

First off Drifty! If it isn't already, it's &quot;very&quot; soon to be a legal requirement that all new fitted boilers &quot;must&quot; be of the condensing variety.
The horizontal flue length varies from boiler to boiler. That's a manufacturers thing! I'll check the positioning thing, but I suspect that will be a manufacturers thing as they not only need to comply with BS, they also need access to it for repairs/servicing/etc. I'll dig the stuff out tonight and check for you though!

I thought boilers had to be direct onto outside walls.

Peter
I may have confused things a bit here, my boiler is a condensing unit, I just mentioned that as an aside so as to ensure nobody thought I had a combi, but Drifty is talking about combi, they are different arent they?
Also his would be considered new or re-site?

<font color='#0000FF'>Peter,

Much appreciated, though if you forget I'll let you off. Again.

Matt,

A boiler does not have to be on an external wall, only vented through one (or vented via the roof) as the air for combustion is drawn in the flue and the exhaust expelled.

Then of course there is the open flue type or the fan assisted typw. &nbsp;Get the manufactuers instructions as it depends on what you have as to where you can resit it.

Of course im sure you will have thought about resiting mains water connection etc as well.

Mind you to do the gas you have to be corgii registered otherwise your breaking the law. &nbsp;Big Gas Board dont take kindly to such things if leaks occur in the future.

<font color='#000080'>Assuming it's RS/FF combi it can go in any room or compartment- Electrical Regs apply if you put it in Bath/Shower room. Flue extensions/bends expensive so nearer standard (ie outside wall/ roof) the better. Usually allowed 3-4m horizontal flue length.
RS/BF combi, again, any room but needs outside wall to mount on.
OF combi- rare beasts nowadays, more restricted siting-wise and needs vents to provide air for combustion.
Closer to HW outlets- kitchen /bathroom the better. The further from Gas meter the bigger the supply-pipe will need to be. If it's 8-10yrs old fit a new one- they'll stop making parts for it soon (if they haven't already!) Should be some bargains about soon with the HE Regs coming into force April 1st 2005- just reminded me - a condensing boiler also needs pipng to a drain-point for condensate.
Moving boiler from kitchen = new kitchen &nbsp; &nbsp;... &nbsp;.. OUCH!!
Hope this helps,
