I have a potterton promax he, finding that when its on, getting fumes, its not gas smell, i have had a sniff about but cant find where ? what can cause this. i dont know about the boilers history, if its ever been opened, or serviced.
At work we have these huge square heater with heat vents on the top, i would say the smell is similar. With this boiler being sealed,i cant see how fumes can escape.
 
Best official advice is to contact your local emergency gas service/ supplier, in the South it is Southern Gas Networks, 0800111999 will be different if you are elsewhere.

They will come out free of charge in a max time of 2 hours, if in any doubt of the boiler they will make the situation safe.

Please turn off the gas.

Kev.
 
do as already stated call o8oo 111 999 and get someone round to look at it. in the meantime turn it off.
 
Thankfully you can smell Carbon Monoxide, not a lot of people can :sleeping:

Hopefully nothing but best to be safe eh??

Could also be some electrical contacts slowly melting themselves till they set alight ! please get it looked at tonight.
 
When ive fitted these from new ive always noticed a smell. Not easy to describe, maybe like oil or new engine sort of smell, or a burning smell.

I have bought a carbon monoxide alarm and placed it directly above the boiler.Also just to make 100% sure that the alarm is working as it has not gone off, i put it under the car exhaust, it works.
 
What about other appliances in your house and neighbours houses. It is better to get it checked out call the esp as told they will be out in 2 hrs usually and have the equipment to test for fumes and gas leaks. 0800111999
 
Carbon monoxide alarms are not designed to alert you of Gas/ Smoke.

If you are happy to sleep tonight without having it checked :rockon:.

I will sleep well tonight.
 
I think people are over re-acting, you cannot smell CO, these boilers smell when new, it could be that

So, for the third and final time; how long ago was the boiler installed?
 
I dont know , how long has been in sorry , i did say i have no known history of it.
I presume a seal has gone somewhere Hence im asking if there could be other possible reasons. ie has something else gone in the boiler, that can cause this , i can afford an engineer to come out and replace seals , but anything else im not so sure.
 
Thanks guys for the advice , i am fully aware of the perils of gas and carbon dioxide.

the reason why im asking is that i had an engineer out to check it over last week, and he did not notice anything,
 
Exactly you cannot smell CO but, with an experienced nose! I think I can smell when a boiler is not working well.

WHY NOT PHONE 0800 111999 TO MAKE SURE !


Until the boiler has been inspected the official action is to turn off and make safe.

i dont believe it is an emergency enough to ring the number, when i can wait for an engineer to come.
All i want to know is what can be the cause of it??
i bought the boiler from ebay , had it fitted , but guy would not gaurantee it as its not a new boiler.I was not here when he did the safty checks , and her in doors did not take much notice, we have not had the heating on , just hot water, but now when we put the heating on , its when the smell comes. cant say if the fumey smell is present when using hot water, but its noticable when the heating is on.
 
lol i only want to know causes of this not that me and my family can die , the boiler even though, manufactured in 2007 looks clean , still had celephane on front cover. the top of the boiler still very very clean. guy advertised it as brand new ??? it had been used at some point in its life, how long for , i dont know.
i did not buy the thing directly through ebay. i made him an offer to take it off and bought that way. so im shagged for comebacks.

All i want to know is what possibe causes , i have had a look at the boiler , there do not seem to be scredriver marks on the inner casing screws. i dont know if it has ever been opened up.
All i want to know is what can cause fumes, it cant be bad fitting flue, the boiler will not fire up if this was the case.
 
iv noticed a funny smell from the steam when boiler condensing when condensate pipe not connected properly , have you checked that ???
