So I am building my herms rig, and wanted a seperate heat exchanger from my HLT. I picked up a coffee urn from the thrift store for 2 bucks, and grabbed a big stainless pot for 6 bucks. I got my buddy to pick up 15 ft of 3/8" tubing for the coil. I am using a 110v 1500 watt element with a renco to control temps. I instafoamed it so it should be nice and insulated. For the lid I mocked up a wood lid, that I may just keep, added an 18volt drill battery with a stir rod JB welded on. I have a AC/DC converter to run it. Its setup to go, just have to wire it in.
