5248A Suburban SW12DEL – 12 gallon; 12,000 BTU/h RV Water Heater

5248A Suburban SW12DEL is a 12‑gallon, 12,000 BTU/h LP gas + 120V electric RV water heater built for high‑demand hot‑water use in larger RVs. It uses Direct Spark Ignition (DSI) for safe, automatic burner control and includes an electric heating element for dual‑mode operation. LP gas, electric, or both can be used at the same time, giving faster recovery for showers, dishwashing, and multi‑user hot‑water needs. The porcelain‑lined steel tank, anode‑rod protection, and insulated jacket deliver long service life and excellent heat retention. Its standard Suburban 12‑gallon footprint makes it a direct replacement for most OEM installations in fifth wheels, travel trailers, and motorhomes.
