Seaward products waterheater heating element

[phorvati]

Does anyone know the thread size for 120V/1250W heating element that comes with seaward products 6 gal water heater. I know its 10-ohms so it would not work for 12V applications. I'm hoping thread is equivalent to one of these.

My fourwinds II load diverted is dumping access current to a 1 ohm 225W load resistor which i mounted on piece of aluminum plate to act as a heat sink. Its been so windy that the load resistor is too hot to touch!
