I just received one of those 48lt el cheapo boilers, It does not have a concealed element so I proceeded to make a false bottom from a Pizza tray from Kitchen warehouse and drilled a hole in the side for a thermowell, so far everything OK. Today I filled the urn to the required depth, fitted the sensor and turned the control to boil as I will be controlling the temp with the PID in my control panel. The control panel also has a volt/amp display and it can also be controlled manually instead of using the PID. The ad on Ebay says it is a 2000w element, but my volt/amp meter is showing that it is pulling 12 amps which would indicate that by using ohms law that it is in fact a 2800w element, I wondered why the plug was getting warm when I did not use my controller and plugged it directly into a 10 amp socket.
