Boilers in bathrooms - Yay or nay??

[ozymandias]

So, it's time to fit a new boiler. Although ?less reliable I need a combi to free up space where the old cylinder is...
Question is, can I put a combi boiler in the bathroom?? I know there are 'zones' for lighting in bathrooms depending on how likely the installation is to be splashed. What about boilers?? I'm not planning to put it over the bath or anything, probably in a cupboard but still within the bathroom.
What colour will the buildings regs man's face be??

Cheers,

Oz.

IIRC, things in bathroom cupboards only count as "not in the bathroom" if you need a tool to open them. For example, shower pumps under the bath must have the panel held on with screws.

"Tool" includes a key, so you could put a cheap lock on the cupboard door.

Obviously, no switch that you can touch inside the bathroom.

there's a a good PDF on Bathroom Zones (do a search) but I don't remember it mentioning cupboards.

You want the Electrics UK forum.

Good thing about this forum is that someone will soon correct anything thats wrong. So I'll say my bit which I believe is right and see if I get corrected.

Here goes.
Combi's are no longer permitted in zone 1 although existing appliances do not have to be moved.
They are allowed in zone 2 or 3 but must be fully earthed across all the metal pipes going into it. The electrical isolation point must be located outside of the bathroom.
A cupboard is preferred and IMO is not 'in the bathroom' I haven't heard or seen anything about the cupboard needing a 'tool' but it certainly makes sense to exceed legal requirements in the name of safety.

No they won't.

Alas, as this is the Plumbers forum, right or wrong, someone is bound to disagree.

The sparks are much more tolerant and calm.

No they aren't.

 

[JohnD]

Yes they are.

 

[Softus]

I agree.

 

[JohnD]

You're wrong.

At least I'm not a ****.

Oh. Actually I am.

to my knowlege not allowed as it as the potential to kill via monoxides still due to the damp atmosphere in which it could placed(corrosion) bathrooms so i believe prohibited bedrooms below x kw, if compartment in bathroom then it may need compartment ventilations if allowed to use compartment in bathroom+ frost protection from atmosphere.

dont ask me im only doing my acs

Doyle you r on right lines,, but thinking of open flued appliances. Room sealed allowed.

Under BS-EN7671 you are allowed to put a boiler meeting a stated IP rating (can't remember if it's IPX4 or 5, manual is in the van) in the zones providing it is not under, or would be sprayed by a shower.

Other items, like the fused spur, would need more sensitive siting, although as a boiler is deemed a fixed appliance, it could still go inside the bathroom.

The earth bonding at the bottom of the boiler is not required, providing supplementary bonding is carried out properly in the bathroom to exposed metal parts.

Where you have an electrical appliance which is touchable, the 'earth' bonding should be linked to a local earth continuity conductor in the bathroom (eg: the earth of the supply to the fused spur) rather than back to the main earthing terminal of the property.

as long as its ip rating is correct and the wiriing meets bs7671, its all gravy.
vailants are ok ideals are not.
