Aren't you garage brewers worried about all the steam getting into everything in your garage. I keep picturing water damage on a slow scale![]()
I have a new brew-in-the-winter system which was first successfully deployed on December 3rd. The moisture thing has always been a concern for me, as my walls and ceiling in the garage are insulated, and I don't want steam rising to the ceiling and condensing in the insulation.
So until Dec 3rd, i always brewed w/ the doors open. Cold, I know, but if the temp approached 40, I'd do it. I'd position a fan to blow across the steam column rising from the boil kettle, directing it outside and preventing its rise to the ceiling.
But in the search for something better, a friend and I developed this:

A box fan in the garage window, sealed on the side w/ scraps, and a "hood" over it to direct the rising steam out the window.
It only works well if the service door is cracked to provide makeup air, and that just makes the garage cold. So we used a propane heater to warm it up inside, and it actually was comfortable with just a long-sleeved shirt.
Before anyone asks, the wooden bench behind the burner was cold to the touch.
This setup worked so well I was just shocked. There's makeup air so the exhaust from the burner under the kettle, and the propane heater were never an issue. I'm hoping to get a Blichman Hellfire burner in the relatively near future; might have to move it away from the bench. If so, I'll extend the "hood" a bit if necessary, but I have little doubt it'll all work.
BTW, my friend supplied the propane heater; I just bought this from Menards to use for future brews: portable convection heater. Got the 11 percent rebate so the price was reasonable.
