Can anyone give me ideas on how to heat a metal chromed roller to maintain 120 degrees on the outer surface. I currently use a pressurised water heater and a hollow mild steel chromed roller with a 12.5mm thick wall. Can it be done with electric rather than water? The roller has a diameter of 6" and is 750mm long. It also turns at 40 rpm.
