I retired my old mash tun for a new 70Qt. Cloeman Xtreme. Thought I'd be scientific and calcluate the heat capacity by adding hot water to the tun. I'm a little unassured of the results:
tun at start 73
4 gal. hot water 162.5
155.8 @ 5min.
153.8 @ 10 min.
152.2 @ 15min.
150.5 @ 25 min.
149.5 @ 30 min.
if I use this link to calculate equivalent water vol.:

I get about 3 quarts or 6.26# of water. This inputed into BS causes my water temps to go up quite a bit compared to using tun weight and spec heat.
I've made three batches with this tun and had problems hitting temp but I don't see the type of loss over time that this test showed.
Does this sound right? Only thing I noticed is the lid on this cooler is easy to open - maybe loosing heat at the lid?
Thanks,
Mike
