Product Features & Fitment

Suburban water heaters are widely trusted across the RV industry for their high-recovery capability and long-term reliability. The SW10DE features a porcelain-lined steel tank built like residential water heaters, combined with an anode rod that absorbs corrosive water action to protect the tank structure.

The Direct Spark Ignition system enables convenient remote lighting via an interior wall switch. With dual LP gas and electric heating capabilities, you can preserve propane by running on 120V power at campsites, or run both heat sources together for maximum recovery rate. Backed by Suburban's 2-year limited warranty, it is an ideal replacement or upgrade for standard 10-gallon cutouts.
