Anyone else undershoot their strike temp using these? I was targeting 158F today and ended up at 152F. I'm not sure if it's an issue with my calculator or whether it's the cooler.

Eric, I lost < 2 °F over 75 minutes.

I too did not lose heat with my 2-gal cooler but I also took precautions.

That works.

I tried something a bit different this time around.

I filled the mash tun with the hottest water I could get out of my tap and let it sit while I prepped and heated strike water.

After my strike water came to temp I dumped and refilled and let sit covered for a minute while I got the rest of my stuff ready.

My temp was steady at 148.7 °F and I ended (after 75 min) at 147.2 °F. Not bad.

I used to preheat my mash tun prior to doughing in with extra hot water.  Now I just make sure it is out of my cold garage (during the winter) the night before I mash in with no issues hitting my mash temps.  I do set my strike water a degree or two higher to account for this consistently though according to Palmers calcs. One less step, and less work for me = yay!  ;D

It made sense for me to do what I did because it didn't really add any time to day and was extra insurance.

Gotta love those Palmer calcs!

If have to dig to find it but there was a great post on HBT from a guy with a pretty heavy thermodynamics background where he broke down the derivation of the equation and showed where Palmer simplified it. It was very interesting to read.

I will say this: I need to modify my hose braid setup. I had a real issue with it closing up on me. I think I need to make it longer so it sits on the bottom of the cooler.

Same here. I bring in the cooler a day or two before brewing and leave the lid open . Makes my strike water differential pretty much the same all year round.

I may have to go back to my tee off the outlet and a circular hose braid around the interior circumference of the cooler.

I initially shortened it because why have a long circular braid that doesn't benefit the draining of the mash. Turns out a benefit of a circular braid setup given the small size of the cooler is I can stir unobstructed.

Also, per Denny's mash/sparge video thread and the Red X color thread, I'll be trying a length of hose on the outlet from now on.
