Pundmann Therm 6L AC/DC Water Heater (12V + 110V)

The Pundmann Therm 6L Dual-Heater Boiler offers the ideal balance of capacity and compact size for full-time van dwellers and weekend warriors alike. With dual 12V DC and 110V AC heating elements, you can tap into any power source — your auxiliary battery bank, solar system, or campground shore power — to always have hot water ready.

You can standardize with 2 rods, which is very efficient, or you could opt to add an additional heating rod to zap water quickly.
