High CO levels

Our gas water heater is 15 years old. An energy assessment firm found the levels of CO venting from the top was 1500 ppm. He claimed he had never seen such a high reading in 20+ years in the business. The flue was not backdrafting, and we have several carbon monoxide detectors in the vicinity that have not set off any alarm. Does this high CO number spell trouble?

Welcome to the forums.

I'm assuming they measured that CO in the airstream going up the chimney..... not leaking out into the room. You should have the water heater checked immediately. It may just be a matter of cleaning the burner area of rust. At 15 years it's almost time for a replacement anyway.

If you don't know who to call.... call your gas provider. They usually have good technicians at a very fair price and many repairs are no charge. Just don't wait..... call now.

Under certain circumstances..... it can be spiders. Anything that restricts the air to the burner.

This is the time of year that stink bugs are looking to get into the warmth.
I see therm all over my house.

Tried to post a photo, but it won’t work. When the dude went to take the water heater away, the entire flue was packed with dead bugs. Heater was well past it’s prime, but it’s a good thing to be aware that those darn bugs can actually kill you!
