I just looked thru all 14 pages and I gotta ask:

Would it not be easier to just have a HERMS coil in the HLT like in the Electric Brewery HLT?

To save a lot of money you could just use copper instead of stainless.

Is direct fire RIMS better than HERMS as far as for making beer, keeping temps???

Just wondering since I plane on building a version of the electric brewery HLT to use with my setup except not electric. Seems a cleaner easier to maintain option than trying to insulate my MLT. Just making sure I am not missing something?

I agree Akthor, but to each their own.

Here's my $40 solution to the same quandry:

My eyeballs. If my MLT is at 153, and the HERMS output is 153, then the mash is 153. The key is the size of your heat sink. The smaller the HERMS HLT the more it gets leached and therfore needs adjustment. I use a 26g HLT with a 15.5g MT so it's pretty damn rock stable with a pilot light. The only downfall is that when I ramp up temp I have to light the burner under the MTfor 5-10 mins, but if you're continouosly circulating/vorlaufing (herms) then it's a non issue. you're just raising the base of the MT the same rate as the HLT.

I built this direct fire MT last winter. I was fairly easy following the post here. The main issue I had was making sure the bulkheads didn't leak. It took some time and fun discovery finding leaks during water tests and then after using a few times. The bulkheads would move depending on outside temp and just not paying attention.

This winter I decided to check insulation. I removed the sheathing and found that the insulation held up well but was obvious that there had been leakage. The main evidence was the rusting on the wool.

I bought some new rockwool from McMaster ($7). I also decided to add a layer of ceramic insulation and find some bulkheads that would ease my paranoia. I found new bulkheads at brewhardware. Bobby pretty much guarantied that you could crank these down and they would not leak. Sold. SO purchased them and cranked them down and did leak tests. NO LEAKS and tight. They will not budge when connecting and disconnecting the quick connects. Awesome product - True Weldless Bulkheads. (https://www.brewhardware.com/product...ulkheadfem.htm)
