Boiler condensate

Jan 16, 2013 5 Replies

I'm feeding the condensate output of a boiler into a bucket for a few days while I'm working on a kitchen. (It had been connected to a sink drain.)



Are the vapours from this liquid dangerous in any way? If so then I'll try and route it outside instead.


It's mostly water with a bit of dissolved carbon dioxide. Slightly acidic, but no more harmful than tonic water. Still, wouldn't drink it!

No. The gotcha might be that the drain from the boiler may allow flue gases exit via it and thus into the room, that wouldn't be good. However most (if not all) boilers have a water filled trap to prevent that happening.

Not especially. Might be mildly acidic (sulphuric, carbonic and nitric) but that's about it. Might be a few organics in there as well, depending on how well its burning..

People have actually drowned in that stuff. Be wary.

Kills more people than anything else that stuff. Informative site.
