Looking to build a stand alone heat exchanger to run a herms coil. I'm looking for a little guidance on doing it right. My plan so far is to use my old 5 gallon stainless pot, with a 3/8 copper coil, and a water heater element. My plan so far is to use this controller: http://www.coleparmer.com/catalog/pr...sp?sku=9352002
and an element similar to this: http://www.plumbingsupply.com/images...ment-02203.jpg
I have a couple of questions. Do water heater elements have to mounted horizontally? Am I going to need an ssr? Source? Should I go with a pressure cooker rather than a regular pot?
