Water cold in your RV? Is it time to upgrade water heaters because your hot water tank isn’t putting out enough hot water for you and your family while at the campsite? Suburban® makes a 12 gallon water heater with an electric ignition that gives you all the hot water you need for showers and dishes at an affordable price!

If you want a water heater that relies on LP Gas and electricity with an easy to activate electric ignition, then this is the tank for you. The Suburban® Direct Spark/Electric 12 Gallon Water Heater has a direct spark “on” switch that when combined with the optional remote wall plate turns on the water heater wherever you install the switch (remote switch sold separately).

Love dry camping far away from the hustle and bustle of the city? Or is your place to be at the campgrounds with all of the wonderful hook-ups? This Suburban® 12 Gallon Water Heater runs on LP Gas and Electricity so you can camp wherever you like as your water heater heats up your hot water.

The best water heaters on the road today, Suburban®'s line of durable, porcelain-lined steel tank water heaters includes FAST RECOVERY with sizes and features to match the requirements of almost any RV.

All Suburban® Advantage™ RV Water Heater Tanks Feature:
- Convenient exterior gas line connection
- One-piece, die-formed metal control housing that protects controls from the weather
- Copolymer insulation jacket specially formed to fit the tank for additional heat retention
- Anode Rod Protection
- Porcelain Lined Steel Tank

The limit switch, reset button and on/off electric element rocker switch (if applicable) are conveniently located in a housing behind the removable outer door. The electric heat element and 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.

When a Suburban® Advantage™ 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® Advantage™ tank is pressure tested twice during the manufacturing process to ensure its integrity.


For all of your RV Parts needs Dyers has the replacement parts. You need a new water heater valve or anode rods? Maybe you need a brand new water heater? We have all shapes and sizes at your RV online superstore right here, at Dyers!
