My cooler weighs 16# alone on my postal scale, plus 2# more in copper manifold. Copper has a different specific heat than plastic (0.3 vs 0.092 in BeerSmith), so I added a little bit to be sure to compensate for the steam losses from pouring in the strike water.

If you're stirring like crazy, you not be using a panel or coming in a little hot and try to cool it back down a degree or two?
I think it must be difference in software. Googling I find beer alchemy users in my range and lower, about #1 while beersmith users have numbers as high as #40 to get it dialed in.

Best practice appears to be to actually measure your own thermal mass by adding a full charge of strike water without grain, letting temp settle, and measuring that number. Then you run your calculator without grain, known strike temp, adjusting thermal mass to "solve for" actual strike temp. I am going to go ahead and do this on my next few batches since I always add the strike water to the cooler before the grain anyway. Just will let the strike water settle temp wise before adding the grain.

Be sure to simulate mashing in for a realistic result.

Have fun stirring in and breaking up imaginary dough balls.

Hmmm first thought you were messing with me. But actually a good stir is important to get right number.

Thad - I like the design of your manifold, very clean and professional looking. I think I'm going to use the same setup once I pick up my cooler sometime this week.

One quick question, what are the two fittings you used to connect the silicone tubing inside of the MLT? It looks like you have some sort of plastic fitting connecting to a 1/2"x1/2" Copper Threaded Adapter Fitting (Lowes: http://www.lowes.com/pd_22627-137-CL603-2_4294822005__?productId=3505168&Ns=p_product_avg_ rating|1). and then it looks like you are using something other than the standard cooler bulk head fitting on the other end. Any insight would be greatly appreciated.

Thanks!

Thats a nylon barb and a copper theaded thing... yeah...

Lowe's had them both on the pegboards in plumbing.

The bulkhead is the standard one from Bargain Fittings.

I'm sure the nylon fitting is absolutely fine but generally nylon stuff is rated for cold water only. You probably want polyethylene or polypropylene for preference.

Dynalab says nylon is good up to 210F (99C), melts at 420F (216C).

It's not that the stuff melts. It is susceptible to hydrolysis. Especially in the presence of dilute acids.

At least, that is true for nylon-6,6 which is the most common type. There are other grades of nylon that resist hot water better.

I mean, it's not like nylon stocking immediately go into holes when you wash them, but there is a gradual degradation which means that nylon parts are not used in hot water plumbing for example.
