Suburban SW10DELC 10-Gal DSI Gas/Electric Water Heater | 5330A

Reliable hot water for your RV with the Suburban SW10DELC 10-Gallon Water Heater. Genuine Suburban OEM 10-gallon dual-fuel water heater with DSI (Direct Spark Ignition), 12,000 BTU LP gas burner, 1440W Incoloy electric element, and corded configuration. Fast 16.2 gph recovery when running gas + electric simultaneously. Includes multiple durability enhancements — porcelain-lined tank, replaceable anode rod, and one-piece die-formed control housing.

⭐ Fast Recovery — 16.2 gph with Gas + Electric Together

Standout performance feature: run both fuel modes simultaneously for a fast recovery rate of 16.2 gallons per hour. Individual mode recovery:

• Electric only (1440W Incoloy): 6.1 gph
• Gas only (12,000 BTU LP): standard 12K BTU recovery
• Both together: 16.2 gph — meaningful improvement for high-demand periods

⭐ Dual Fuel — Gas AND Electric Operation

Meaningful flexibility across power sources:

• 12,000 BTU LP gas burner
• 1440W Incoloy electric element
• Simultaneous operation for fast recovery

⭐ DSI (Direct Spark Ignition)

Direct Spark Ignition provides automatic burner lighting — no manual pilot lighting required. Meaningful safety and convenience improvement over pilot-light systems.
