new boiler sending odor through the house
We installed a new Weil McLain steam heat boiler about a month ago. An odor filled the basement right after installation but it was infrequent because of the mild weather. Hot water is also produced by the boiler. We contacted the installer, a major area oil company, who first said it's new boiler smell from coatings that have to burn off, give it a few days. A few days later, still smells. Company made 2 visits. The first tech said the "insulation in the fire box had to cure" but since the boiler wasn't running regularly it might take a few cold days. A few cold days later smell continued and of course got worse since the boiler was running. New tech came out, same answer, needs a few more days for everything to work through the system. Few days more, still stinks throughout the house- a sort of sweet mix of bbq and oil. Supervisor came out and noticed a leak in one of the relief valves. Valves were replaced on Saturday and they drained the boiler and dumped some "silicon" chemical that sent a harsh acrid smell over the house that took most of the day and night to dissipate. So we were told a few cycles and all would be good. Not so. Now Monday and the basement still stinks from the original odor, it's still coming through the house, maybe just a little less. But could be the 2 fans we have going 24 hours to try to move the air out. It's a month now, the basement stinks, I've got no good answers from the company and I'd like to know what I'm smelling, which cannot be great to be breathing with closed windows in the winter. The company says this is the first time they've ever had this issue and make it sound like everyone has smelly boilers and I think they expect us to just get used to it. By the way, we lived here for 25 years with the original boiler without any smell issues. The firebox was worn on the old unit and we were advised we might as well replace the whole thing rather than repair. Now we're worse off than before. Any ideas, solutions, answers?
