I decided to build a newer, bigger, better, (mostly blue) mashtun . .
Coleman Extreme 70
All stainless outlet with Quick Connect
Dry Fitting Heat Manifold . .
Holes for Manifold Inlet/ outlet
Installed Braid Pickup
Soldered Manifold before clean up (Wish I would have had some Stay-Brite 8 low temp solder) 
Testing all the fits before cleaning up the manifold . .
Lots more to do . . but it’s a start!
So a manifold and a braid. How does that work. Inquiring minds want to know. ;D
The braid is for the wort pickup . . the manifold is a completely closed system and basically an indirect heating element to hold the mash temp rock solid for the duration OR to step mash if the need arises. I will have a separate heated water vessel and a March pump that is PID controlled to circulate hot water through the manifold to hold and/ or raise the mash temps . .
I have the exact same cooler that I’m in the process of converting. Except I will be nowhere near as innovative or thorough as you. Nice setup!
I’m putting up walls and shelves in the basement. It’s about time this gets done so I have more room down there.
Kai
Thats purdy! Nice job dhacker! ;D
dean,
You ain’t seen nuthin’ yet! 
We made a big Snowman in our front yard 
Dhacker, are you going to stir the mash or recirculate wort while heating it? Without that I would be concerned about uneven heat distribution.
Kai
Twin stir motors with 10 inch stir blade paddles. And I could recirculate if necessary.
My current Gott 60 mash tun is similar except It has no heat exchanger and used 4 model airplane propellers. Hence I called it:
Hack’s Whacked Orville and Wilbur Mashy Tun!
Here’s a pic of the current Gott 60 . .
Your mash tun plays piano!! Cool.
Want to do mine when your done
Need to do some drawing and figure my space out too…
Better yet, need to get a back-hoe in here and blow out a wall for a walk out basement >:(
Learned that 1500 watts is enough jules to boil water but not wort
Ben and I may hit Lowes before the Patriots game for a 2K element.
You mean in 5 years
That’s how slow the progress has been so far. But I’m getting there. The fermentation cellar and lab is pretty much done. I put insulation in the walls to keep the option for adding temp control to that space. I’d like to keep it at 15C year round.
Does anyone know about building codes and what to look out for when building walls near a furnace and an hot water heater? I’m interested in minimum distances and necessary ventelation.
Kai
5 years might be about right 
On the furnace and water heater, check with the manufacturer of both.
Cool. I was always curios where to find that. But I guess I never looked hard enough.
Thanks,
Kai
I know all about it from when I did the wood stove installation
I’d think those codes depend on the location.
For example in Cook and DuPage Counties in Illinois (Chicago) you need to run all electrical wire in conduit. 1 County further west you can use romex.
I’d think when it comes to heating-there would be some rules.
But I just need to shut up because I need to build some shelves myself and ideally a fairly basic workbench. (something to clamp my grainmill too)
Even non exposed wires? E.g. in walls.
Kai
Yep. It’s a MOB (I mean union) thing. Actually they blame THE GREAT FIRE that it’s been that way ever since.
Would not each individual municipality have its own building code?
At least around here.
