I looked up some data, it looks like I need 40 Ohm, 392 watt resistor,
so I bought two 20 Ohm, 300 watt resistors on ebay, that should do
it.


300 watt is probably going to be too low of wattage.

Electric water elements can be used in a pinch...

--just be sure and buy the kind that won't be damaged if they are operated while not submerged.
