Who it fits
Good fit for
This heater suits RV owners who need reliable hot water in tight spaces. The 6-gallon capacity works well for one or two people who do not take long showers. You will appreciate the dual fuel system if you camp in remote areas without shore power. The gas mode provides a faster recovery rate of 10.1 gallons per hour. The electric mode is ideal for hookups at campgrounds. The compact footprint ensures it fits in most standard RV water heater compartments without modification.
Who should skip it
You should skip this unit if you need a high-volume hot water supply for multiple simultaneous uses. The 6-gallon tank empties quickly during back-to-back showers. If you prefer a larger capacity, Suburban offers 10 and 12-gallon versions. You might also look elsewhere if you do not want to manage two fuel sources. The electric element is optional, so you must ensure your RV wiring supports the 1,440-watt load. This model is strictly for RV use and not suitable for residential installation.
Verdict: The Suburban SW6DE offers a practical blend of compact size and dual-fuel flexibility for RVers. Its efficient heat transfer and durable tank make it a solid choice for small groups.

BTU/h: 12,000

If you plug into campsite power, the 1,440-watt electric element offers a 6.1 gallons per hour recovery rate. This option lets you heat water without using propane. The Direct Spark Ignition system starts the gas burner automatically when you turn on the hot water. You do not need to manually light it. The exclusive flue tube design slows combustion to optimize heat transfer. This means the unit uses fuel efficiently while heating the tank. Maintenance involves checking the replaceable anode rod. This component protects the steel tank from corrosion. It also serves as the drain point, making winterizing or cleaning easier.

Before You Buy This Unit
You need to verify your RV’s electrical system supports 1,440 watts for the optional heating element. If you plan to use shore power or a generator, ensure your wiring handles this load. The unit requires a 12,000 BTU gas line and proper venting for safe combustion. Regular maintenance is essential. You must inspect the replaceable anode rod periodically to prevent tank corrosion. This rod also serves as the drain, so check it during seasonal preparations. The porcelain lining helps protect the steel tank, but upkeep remains critical for longevity. When comparing this to 1 other options on this page, note that this is a tank model. It provides a reservoir of hot water, unlike the instant heat from tankless units. You will need to wait for recovery time, which takes about 10.1 hours for gas-only heating. This fits well if you prioritize steady supply over instant delivery. Ensure your space matches the 12.75-inch cutout requirements before purchasing.
