The best water heaters on the road today, features to match the requirements of almost any RV. Heated water attacks all metals, but not porcelain. That's why Suburban uses a porcelain-lined, steel water heater tank with an anode rod to "absorb" the electrolytical action - just like your water heater at home. In fact, when a Suburban porcelain-lined tank is properly maintained, tank life may double or triple its three-year limited warranty, saving owners the cost of premature replacement. In addition, every Suburban tank is pressure tested twice during the manufacturing process to ensure its integrity.
