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.

Fast recovery means more hot water and fewer cool water cycles. Suburban also uses a copolymer insulation jacket specially molded to fit the tank. This does a better job of retaining heat than the "cardboard" style used on some competitive models.

All Suburban water heaters are designed for easy installation, operation and maintenance. The limit switch, reset button and on/off electric element rocker switch are conveniently located in a housing behind the removeable outer door. The electric heat element and combination drain plug/anode rod are also located there. For convenience of installation, rough-in openings for Suburban water heaters are small and less likely to interfere with RV exterior design.
