Boring boiler question here...
Since I moved into my place, it's always released a bit of a sulphuric smell when active, which goes away when the boiler's dormant. I know that the obvious response to this is "Oh my god! A leak!" but the obvious conclusion may not be the correct one. Someone did check the boiler a few months ago and didn't detect anything (admittedly, the gas could've been off for a few hours - I can't remember). Apparently there's an anaerobic bacteria that can grow in boilers that gives off this smell, particularly when the conditions are dark and poorly ventilated, which is true of my boiler closet. Another thing that's keeping me reasonably calm about this is the fact that the kitchen cooker gas doesn't have the distinctive gassy smell - usually the "rotten egg" smell is added by gas companies to warn of gas leaks. I'm not sure if this happens in Korea, but in any case, the gas in the kitchen doesn't smell like the boiler closet. Finally, this has been going on for a long time, and if there were a serious problem I think I'd have felt the impact more directly by now (though I'm also worried that I've subjected myself to some kind of slow poisoning).
I'm ordering a carbon monoxide detector from GMarket, but wondered if anyone else has had a similar issue here in Korea. I'm not sure how useful advice from the US or UK is likely to be.
Thanks!
