Update: Vent hoods! Everything look right?
So a while back, a eagle eyed reader noticed my hot water heaters did not have vent hoods on them and that was a serious safety issue. See first photo. They had an air intake a few feet down the main duct to the left.
So I got a legit plumber in there who added vent hoods to both water heaters and removed the air intake from the duct. As you can see, this exhaust duct meets up with the duct coming out of our steam boiler and then runs up through the chimney. See second photo.
Does this all look right now?
The plumber did a test using a blown-out match near the vent hood to see if it was drawing air in.
He said he knew the vent hoods were required but he actually liked how the original setup was working better.
Any thoughts on this?
Anyone notice anything else that’s an issue in photos?
Thank you all for your help!
