Gas Combi Boiler in Bathroom Cupboard. Whats Regs ?

[julioarca]

My Vaillant Combi Boiler is in Bathroom cupboard, it was serviced by British Ripoff Gas late last year...

They told me that new Regs came into force 2008 regarding ventillation and currently my installation would fail.

What do the new regs state/requirements for boiler in Bathroom cupboard. He said something that even putting on louvre doors would not sort this out?

Cheers

As usual BG are talking a load of carp. Any new regs are not retrospective.

If your combi was fitted to manufacturers instructions and/or regulations in force at that time it will be ok.

What Vaillant is it?

I would guess he is talking about compartment ventilation. Check MIs for info on this.

If its room sealed and he was refering to compartment ventilation then the worst it can be is undersized or poorly configured but would be classified as Not to Current Standards.

If its open flued, which the new regs refered to, then the boiler shouldnt be in the bathroom anyway.

Any new regs are not retrospective

The new vent regs regards OF boilers with ventilation under 90% of required is. Most BBUs ive seen were fitted with undersized vents from new

New regs might have affected it, but it's unlikely.

If it's open flued and the vents communicate with the bathroom, it's At Risk, turn it off.

The electrical regs have changed, perhpas that's what he meant.

SO which boiler, when fitted, and what ventilation does it have?

Out of interest chrisr, what is the problem with open flue boilers and bathrooms ? Is it because in a hot bath blood circulation would be increased, speeding up the effects of co poisoning. This is something I've just realised I didn't know, and I'm asking you cos you're dead clever.

amazingly tonyesque of you dave.

if its one of those Open flued nails then its possible that its ventilation has been classed as NCS up until this month when it becomes AR.

presumably they are ripping you off by giving you valid safety advice to prtect you and your family?

why dont you phone and tell them it wasnt explained properly or you didnt listen and you want to hear it again?

That's what I was thinking too, but that wouldn't have anything specific to do with it being in a bathroom. Would it?

Well I think it's to do with the possibility of falling asleep with the door shut with the boiler reheating the water.
In other words I've forgotten. Namsag or GG will remember, I expect!
I have trouble keeping awake anywhere, any time. It's a bit embarassing at breakfast, the milk from your cornflakes goes up your nose. And when you start snoring while talking to a customer you tend not to get the job. People like me need balanced flues.

Perhaps I have not correctly remembered but I thought that open flued appliances were never permitted in a bathroom?

Sooey. The reason for no open flued appliances goes back to the days off the old gas geysers that where open flued with wall faced terminals and regularly fitted into bathrooms and as people sat in bath topping it up . The flue pull was never the greatest and people would regularly be overcome with fumes.

Prior to 84 open and flueless appliances where allowed and believe it or not if they work ok and show no signs of distress (and obviously meet room volume and vent req`s) they can be left and classed as NCS. Anything fitted after 84 even with proper vents etc is classed as AR

last thing that was on my mind

It's just that this case, assuming we have the facts correctly, just seemed way over the top.

 

[sooey]

Great post namsag, you're now promoted to my new hero, that chrisr fella's had the elbow.

Just joking Chris, youtheman.

I am sure that Chris will be checking his classroom notes now.

Thats an advantage of teaching, nobody dies in the classroom if the tutor gets it wrong ( as long as he corrects it before the students go back into the field ).

Some students do seem to suffer the effects of CO in the classroom and nod off to sleep. They are usually fully revived at the next coffee break!

Could be CO2 and not CO

Open flued appliances need ventillation, usually provided by a vent straight through the nearest outside wall.

So if an open flued water heater was installed in the bathroom how many occupants are going to lie in the bath with a howelling gale blowing through the vent?

Since the chances of the vent being covered up are near 100%, open flued appliances are therefore banned.

The wall adjacent/surface terminal position was just another mad idea from the gas industry in an effort to cut costs; just unfortunate that thousands of people died as a result.
