Do i have to resite my boiler?

shindigger

Howdy,
I have a Vaillant combi boiler which has a leaking heat exchanger.
Repair costs around £450 all in.
Boiler is currently mounted in a cupboard with a flue going directly up in to an old chimney breast. System was installed (legally) like this in 1997.

Mounting the boiler on our only outside wall will blow condensate straight in to my neighbours garden where they have recently installed decking. The flue would be roughly 1 mtr from the decking. This would also be blowing out over a shared pathway.
Would the building regs likely have an issue with this, such that i would be allowed to continue to mount my new condensing boiler in the cupboard?
Or do i simply not have a choice due to the nature of condensing boilers.?
Do they HAVE to be mounted on an outside wall to work properly?

The gubmints £400 scrappage allowance isnt really going to offset the cost and all the carnage of resiting a new boiler to the outside wall is it.:mad:

Whats my best bet people?
I have spent roughly £600 keeping the Vaillant going over the last 5 years.
I have been quoted £2400 to site a new Vaillant Ecotec 731 boiler on the outside wall.
Are there any places selling reconditioned standard combi boilers or is that a state crime now too?
Ive been reading up on Condensers and it seems if theyre not installed correctly, they will offer very little in savings.
Scrappage or no scrappage.

Ideally i would like a new boiler on the existing pipes but looks like Johnny Prescott and Lord Mandleslime have scuppered this?
Am i right?:mad:

Cheers for any tips.

Most (if not all) manufacturers will also supply various flue lengths and elbows etc so you can site your boiler anywhere, doesn't have to be an outside wall. My WB was sited in a cupboard central to the house until I moved it during a refurb.

Check the manufacturer's technical pages to see what is recommended/allowed and then you'll have a better idea of what your options are with regards to the flue runs allowed. WB in particular has blueprint type drawings of acceptable flue layouts etc so maybe other manufacturers do too?

Regardless of the regs, siting a flue 1 mtr away from your neighbour's decking wont make for friendly relations. The condensate can be quite extreme at times.

So why does every plumber that comes to my house instantly say that i cant vent up the chimney then? Im not having a pop at you, i genuinely dont know whether theyre having me on or not.
Ive just phoned Worcester and they do a floor mounted boiler that can go up a chimney but i dont think its a combi. Their literature is a bit confused.

What im driving at is the difference between the units ability to go up the chimney and the law.


Re Decking. Shame they werent so considerate as me, when they plonked it under our kitchen window. Ill smoke em out!
Flying freehold type thing, its complicated.

Cheers for your input. Aprreciated.

I might rip the whole lot out and "go electric". Just like Bobby Dylan.:)

I don't know enough to help you with the law and regs etc I'm afraid. I don't understand why you can't have a flue pipe going up th chimney, I had the option of going up from ground floor to loft and exiting through the roof.

I wonder if heating engineers might be more of a help than 'just' a plumber? They might have other alternative ideas?

(I mean no offence to plumbers.)

Thats my fault. I meant heating engineers.
