Suburban Mfg 5148A SW12DEL 12 Gallon RV Water Heater Direct Spark Ignition Gas/Electric

The Suburban SW12DEL 12-gallon RV water heater delivers reliable hot water performance for recreational vehicles with dual fuel flexibility. This direct spark ignition model operates on both LP gas and 120V AC electric power, allowing you to choose the most convenient energy source whether dry camping or connected to shore power at the campground.

Key Features:

• 12-gallon porcelain-lined steel tank with replaceable anode rod for long-lasting durability
• Direct spark ignition (DSI) system eliminates the need for pilot light maintenance
• 12,000 BTU/hour gas burner with 10.1 gallons per hour recovery rate
• 1440-watt Incoloy electric heating element with 6.1 gallons per hour recovery rate
• Combined gas and electric operation provides rapid 16.2 gallons per hour recovery
• 12-volt relay switch enables interior control of both gas ignition and electric heating
• Foam insulation maximizes heat retention and energy efficiency
• One-piece die-formed housing protects controls while providing easy access
• Fits standard 16-3/8" x 16-3/8" x 20-1/4" cutout dimensions

The porcelain-lined steel tank construction resists corrosion from heated water, while the included anode rod absorbs electrolytic action to extend tank life. Each tank is pressure tested twice during manufacturing to ensure integrity. The compact design uses the same door and cutout dimensions as Suburban 10 and 16 gallon models, making upgrades straightforward. Note that the access door is sold separately.
