Idiot guide to back boilers needed pls!

[eva247]

Sassie where was i rude . You dont have a clue, nothing rude in that. But if i needed to be rude to stop you putting someones life at risk i would . simple.

I will put it basic a back boiler can go from being perfectly ok and giving no fumes out into room to being a killer in less than a couple of hours

ok, i'll sleep pretty sound now thanks just kidding, prefer it straight so carbon monoxide detector is a definite requirement then, any recommendations on the best one to get?

basically, if it was your house what would you have?

 

[sassie]

the ventialtion is needed for the back boiler, not the fire. Like i said i didnt need a firguard as one my kids never bothered, two it was never used and 3 all my friends and family never had fireguards so i didnt see the point, but if you feel the need to get one then get one, as for the detectors they can be picked up from argos, wilkos, diy shops, BG etc,etc, and got from about £10 to £30 i believe

I thught that could happen with any boiler not just back boilers

Sassie please stop . No it cant happen with just any boiler a back boiler is open flued and thus takes all its air to burn from the room and if anything goes wrong it will discharge all its products of combustion direct back into the room.
And your wrong about vent only being for boiler . it is based on a calculation of both the boiler and fire inputs combined

Then just out of curiousity why are people with combi boilers being recommneded to have carbon monoxide detectors, you can just explain to me without the aggression in your posts, we arent all born with this information

thanks for your replies and I think under the circumstances, I'm not about to put my families lives at risk so i'll be going with the qualified heating engineer on this one!!! I must say that I dont feel very comfortable with a back boiler (didnt before but definitely dont now!) however, I think I've got a lot of saving up to do if I want to change it for a combi due to all the re piping.
Once again, thanks for clearing up any concerns and putting me straight!

giving advice like this is similar to old wives tales.

it doesnt help anyone while expressed with good intent ultimately is born of ignorance and dangerous.

CO detectors are good and we all should have them as for the rest please disreguard.

Sassie Because it plays on peoples fears and is an easy 40 quid for companys like Bg who buy them for a fiver. I kid you not i have seen these companies sell them to people with electric fires and for fitting in cylinder cupboard when only a cylinder is in there.
Eva a back boiler properly seviced and not messed about with by altering ventilation or original design is a safe enough appliance

 

[sassie]

i think post crossed or mixed, soory the ventilation i was referring to was the air vent in the room, without the back boiler this air vent is not needed, i wasnt referring to cover thing, sorry after reading back it looks like that, but i wasnt, unless BG and the installer of my new boiler have lied to me

 

[waterworks]

Gas fire forms part of secondary flue, so cannot be removed.
Ventilation is required for both appliances ie BBU & Fire.
Any open flued appliance can spill carbon monoxide into room not only back boiler.

Examples being Gas fires not fitted to bbu,s, water heaters, Decorative fuel effect fires etc.

Also any positive pressure room sealed appliance with case seal problem can be just as dangerous.

IMHO providing that a cover is placed over the fire with due regard to fire proofing and ventilation, plus access for services and matenence etc, it would be no problem, if it was a radiator cover, it would have much more free air space than any air vent.

But don't cover room air vent.

 

[WDIK]

in other words dont play around with it

 

[snb]

As Namsag has quite rightly said. You cannot put a radiator cover over a fire and back boiler. If any RGI came across this it would be classed as immediately dangerous. The reason being that there is a possiblity of turning the fire on

 

[waterworks]

The original post said could i cap off the fire and put a cover over it, if the fire was capped off from gas supply but still fitted to boiler and covered by a radiator cover there wouldn't be a problem.

 

[namsag]

Yes there would ....firstly fire cannot be taken off BBU secondly a rad cover cannot be used an appliuance cannot be boxed in like this no matter what ventalation it has built into it

 

[waterworks]

If you read my post i've said cap off fire but leave fire fitted to bbu, and a radiator cover is not boxing it in as long as it is big enough to satisfy requirements in regard to fire it is no different to a fire gaurd.
