Growroom condensation issue

[JohnnyHopkins]

Hello

My flower room shares a wall with my mechanical room in basement. In the mechanical room is the water heater which has an inlet and exhaust ducting. The ducting runs between the rafters above my flower room. With the outside air being so cold now and my room being about 82 it is creating condensation off of that fresh air inlet duct that run above the room. I've tried insulating.
I am thinking about plugging that inlet from outside with some insulation. After all i think they put it there in the event that someone completely seals off the mechanical room? I haven't drywalled the ceiling so air can still comes thorough the rafters and I am also going to exhaust into the mechanical room for 15 minutes every 3 hours. The exhaust air from the grow room will have lots of co2 so I dont know if that makes it any better for water heater pilot light?

Thanks for any help

Wouldn't it have lots of carbon monoxide and not carbon dioxide?

Wouldn't it have lots of carbon monoxide and not carbon dioxide?

as long as it is burning properly no,blue flame-CO2 yellow/orange flame-CO
it should be good but I would still run an CO detector in the room or nearby

Is this fresh air (combustion air) piped directly to the unit? If so, do not plug it off! The fact that there is condensation developing denotes or is evidence that there is air movement through it which is evidence that this heater is sourcing it's combustion air from that pipe. This is an area that I have 20+ years of experience with and work with regularily.

Maybe cut it open and allow it to bring some warm air from inside your grow? Condensation is a Butch.

You say you tried insulating the input ducting. What did you use? Does it have an impermeable surface? The condensation is dripping off the insulation?

Can you put up insulation an plyboard to create another wall thats well insulted the rooms can "share".... Az

Johnny Hopkins, I've given up fighting condensation other than just letting hot air into the ducting which us totally inefficient. If you build a wall around it or find some other way to fix it please update me as I'm very interested.
