Congrats. Same questions as sailorman9. Cheers.

Porter, You are describing a physics problem...and you'll need to know a few things about thermal conductivity of the coils and the tank (it will conduct to the earth around it as described). I would suggest searching: Thermal Conductivity Equations Formulas Calculator Thermodynamics and Fourier's Law I found you a calculator to plug in the numbers: http://www.ajdesigner.com/phpthermal/thermal_conductivity_equation_heat_transfer_rate.php It also shows the formulas for solving each of the variables if you know the others. On nice thing about the calculator is that once you know a couple of the variables...you can play with the length of the tubing. If physics is a scary thought...might suggest contacting the local university's physics department. In the age of "green" this would make for a great problem for grad student to publish for the craft distilling industry. Let me know if you find this out. Cheers, MJC
