Anyone Up for a Mystery?
I'm usually hanging around in the Kitchen Forum, but I had so much success learning the right way to wire my euro cooktop in the Wiring forum, I thought I should try you all on my heater mystery, if you're up for it.
Last year in particular, I was noticing that I didn't really like when the heat was on, though I was also sick a lot and couldn't really take anything below 69 degrees. I noticed that I was having some symptoms that sounded like what they talk about on the news for carbon monoxide poisoning, but I was told repeatedly that there was no way my heaters had a carbon monoxide problem. It got warmer, and I started on the unending kitchen remodel, so I just turned the heater off.
Over the summer, when it was very hot and the really heavy construction was done, I did turn on the A/C without any problem, but it was set pretty high (82 upstairs, 74Â°-78Â° downstairs)and didn't blow that much that often.
It's a two zone, forced air system installed in 2001.
In October, or so, it got cold and I put the heat on. I felt awful and turned it off. My heater guy again said that it wasn't CO and brought a couple of detectors, in my opinion just to appease me, and changed the filters and HEPA filters just because I asked (he said they weren't really dirty). It was really cold so I ran the heat. And didn't feel well. Since I have a lot of allergies I didn't associate it with the heater right away. About a week after the heat went on, the CO detectors went off.
I cleared the house, and left the heaters off for a week or two. Then I got cold again and turned them back on, and the same thing happened. This time I felt sicker, and a week after turning on the heat the detectors went off. So I turned off the heat and huddled in bed. Now that my kitchen is going to be finished I want to be able to use it in Winter, as well as the rest of my house! I don't want to spend another Winter without heat!!
The heater guy said that there were no cracks in the fireboxes. The gas company man couldn't find any problem at the vents. He thought it might be free ambient CO setting off the detectors, but they've only ever gone off one week after turning on the heat. With the heat off for months they're perfectly quiet.
So I got in another heating company that came highly recommended. They borrowed a very very good sniffer. This guy turned on the heat and started sniffing. The sniffer, which alerted crazily for his exhaust pipe, was finding one and two ppm. Nothing more. He said it doesn't accumulate. He looked at the roof and said that the exhaust is 3' above the air intake so it shouldn't be from that.
All I know is that it's cold again and my hands are like ice. It's time to crawl back in bed like a lump instead of washing dishes and putting the kitchen to rights.
Any notions? Any experiences? Please, can you solve the mystery?
