I was hoping to get some advice on setting up a HERMS system. Currently I use a 10gal igloo round cooler for my Mash tun. I am hoping to get a chugger pump for Christmas.
I know the ideal HLT HERMS setup would be to get a coil with weldless fitting out the side of a pot. But in an effort to stay with in spending limits and purchase things as I save the money, I was thinking about getting the below SS pre-chiller coil.
To circulate my wort, I would come out the bottom of my mash tun, into this coil with the tops of the coil just coming out the top of the pot. As far as heating, I would use my propane burner, keeping an eye on temp in the mash. Then back to the mash tun through the top, making a manfold though the lid of the cooler. My final setup, as funds allow, would be to install a heater element though the pot to regulate my HLT with the coil in it
but this will be after I get a new brew pot to use as a BK.
My concern is that coil sitting on the bottom of the pot, with the propane burner running to keep the water hot..will it scorch the wort as it circulates?
Also, as funds allow, I would want to configure this coil to go through the side of the pot
how hard do you think this might be with weldless bulkhead and compression fittings?
Also, is 3/8 at 25 enough to use for a HERM coil?
Any ideas or suggestions??
