Building a HERMS Setup
Posted: Sat May 19, 2012 10:52 pm
I'm going HERMS, no need to go over the reasons, they are still valid and I'm in too deep to go back anyway
So far I've set up my 3 Keggles, I have a sweet false bottom mash tun with a thermowell and ball valve installed. In the HLT I have a 5/8" convoluted copper coil mounted via welded NPT fittings with quick disconnects on the outside, a thermowell, a brewmometer and a ball valve. The boil kettle has a ball valve, a brewmometer, and has been used successfully for about a year.
I'm going to use Ranco controllers to use temperature to control the propane burners and the pumps.
So, the first question is a basic one to building a HERMS system.
Q: How much overshoot will I see in my temperature when using a thermowell in the mash tun to control a pump that pushes the wort through the HLT coil?
The reason I ask is because I am going to do a dry run tomorrow. I will heat the HLT to ~180 manually and then monitor and adjust the temperature manually. I want to see what happens when I circulate water in the mash tun through the coil. My hypothesis is that I will way overshoot my temp because when the thermowell tells the pump to quit circulating wort (or in this case water), there will have been enough heat added to overshoot the mash by a number of degrees.
