Take a look at this write up mr push eject did http://www.wortomatic.com/articles/The- ... n-a-cooler
). Also pm code and ask him he has a better solution to the ground ring and sealing issues than this article. He can show and explain it better than i can.
Thank you. Good stuff. Did not think of the ground wire in this installation for short issues. Good to know.
I did find this rather spendy 3000W option with built in thermostat at Omega;http://www.omega.com/ppt/pptsc.asp?ref= ... EATER&Nav=
1" for the port I have, 3KW, built in thermostat. $280 though. Hard to swallow given the water heater elements, even up to 4500W and in stainless are $30. However, taking into account controller and thermocouple/RTD, and ease of wiring (3 wire, 240V), this may be a winner.
