Water Heaters-advice?
So, the 10g Suburban water heater in my camper has, basically, died. When I removed it, the tank has completely rusted so much, I can't even tell where the leak is. It still heats! Tenacious thing ...

For an electric tankless water heater at a 50 degree F temperature rise, you use about 1 kW per 0.14 gallons per minute flow (assuming near perfect energy efficiency at converting electricity into water heating, which is a reasonable assumption). A 9.6 kW load (the maximum continuous load permitted by code on a 50A 240V circuit--for a continuous load it's derated to 80 percent capacity) will heat a bit over 1 1/3 gallons per minute at a 50 degree temperature rise. You can, of course, get a higher temperature rise for a correspondingly lower flow rate, and vice-versa.
