Determine what combo of heaters will pull 20 amps from the batteries.

I agree. You may just have to measure them and see what sort of resistance they are. (You just want to be sure they don't glow white hot, or the resistance will change drastically!)

I just got finished building a 1KW R.F. dummy load using four 250 watt heat lamps in series/parallel. Comes out to be almost EXACTLY 50 ohms at 1 KW. Sort of a poor-man's "Cantenna". This is one case where a white-hot dummy load is okay. :)
