So late last year, I showed my wife an electric brewery and expected her to laugh. Instead, she said I should get it! I was shocked. Then she explained she liked the idea of keeping all my stuff in the basement instead of hauling it out on the porch and making a mess. Well, whatever works :cross:

Anyway, after doing some research (most of it here), I decided on the High Gravity EBIAB setup. I don't have a lot of room, and I enjoy the BIAB process. I ordered my setup around Christmas, and it all came in quickly. I got this: http://www.highgravitybrew.com/productcart/pc/BIAB-Electric-Brewing-System-p3987.htm#.UyBPPM4z21c

Then the cold came, and came hard here in WI. I didn't want to cut a 6" hole in the side of my house for an exhaust with it so cold out. Finally, Monday, it was above freezing and the hole was cut.

Now the one thing I had a hard time finding a lot of info on was the exhaust systems people use. I did find some useful stuff, but the actual process escaped me. So I thought I'd show a little of mine to help anyone else looking to do it.

First, I drilled a hole with a Milwaukee 6" hole saw. Fortunately, I ended up with just one layer of wood and one layer of hard insulation. It went pretty well. Here's a picture of the hole with my neighbor looking in.

I used a couple of these to get in the house and under the joists: http://www.homedepot.com/p/Master-Flow-6-in-90-Degree-Round-Adjustable-Elbow-B90E6/100062966

I added the fan: Vortex 6" 449 CFM, 1.2A, 136w http://www.amazon.com/gp/product/B001JKYTLG/?tag=skimlinks_replacement-20. I also added a speed controller: http://www.amazon.com/gp/product/B003URBQ1M/?tag=skimlinks_replacement-20

Then a couple of 6" aluminum ducts to get to my high tech hood. The hood design was a concern for me until my brilliant wife said, "Why don't you just use a storage tub turned upside down. It's only one pot, and a large tub was plenty big to cover that.

I ran a test boil of water yesterday, and it worked perfectly! Almost... I had water dripping out of my fan. I am not sure why, but the fan is mounted vertically and dripped out of the bottom. When I got the fan, it said not for wet environments, though I see it's one that a lot of people use. I guess I'll have to keep an eye on it. It did suck all the steam up. Nothing escaped the "hood" that I could see. Overall, I'm very happy and looking forward to my first brew day with it.

Congrats!

As far as the water dripping from the fan, you might want to try insulating the duct to reduce the amount of condensation prior to the air being vented outside.
 
I just did my first batch! Very exciting. It wasn't the time saver I was hoping for, but it was a nice. Everything in one place. It was so easy. Just a few steps that took human intervention. I really liked it and am looking forward to another batch on Friday.
