That's what I do (on a direct fire system), and that seems to be the collective wisdom on HBT. In fact, I don't observe a constant gap between the grain bed and the hottest point in my RIMS loop (in my case, the output of the kettle). It depends on the length of time since I mashed in, the flow rate, the mash thickness, etc. When the gap gets large I stir the hell out of my grain bed, and that usually narrows the gap by a few degrees.
A play on Ed Worts Haus Pale Ale but using Jade hops for middle and late additions. Also will dry hop a small amount before kegging.
Ambient was 60 degrees, but I think my keggle MLT still needs a jacket. Closer to temp today. Set at 151 at exit on tube, MLT grain bed read a stead 146-147. My efficiency was off .003. Not bad for single infused mashing. I did add an extra # of base malt.
Tasted and smelled good. Still no scorching or problems I couldn't fix. Even though I'm in the garage, vented to outside, the whole house had a wonderful sweet malt aroma to it.
My question is with condensation with all your lighting and electronics mounted how is it wirking. my next step is a hood.
If you get advice on an electric brewing rig, you need to take it to a licensed electrician or two to have it looked over.
This stuff can kill you. When it comes right down to it, we're just some dudes on the internet.
I have seem some TERRIBLE advice on here in the past few months. I may even be guilty of bad advice myself.
Hood is under construction. I've brewed 3 times on it so far over the last two weeks. All three times I was in the 60s so I opened the garage door and turned on a small fan. The BK is right by the garage door, so it rolled right out.
Not worried about electronics, but have some sealed LED spots that I may use in the hood and over the work space. Just need to see how brite they are and if they will work. I do not like the hanging light I have now.
