We need to design a heating coil in a tank containing a heavy crude oil, in order to maintain it at 160 - 170 °F. We are also considering adding settings like “presence of hot water radiators” (so that our algorithm would recommend Boilers over Furnaces) and other features. Either your coils are slightly different resistance, you’ve got heat spots or your coil leads aren’t fixed into your deck posts properly. It is most economical* type of heating/cooling you can get.
