The Suburban Mfg Sw6Del with H 6 Gal Dsi/Elec boasts a 6-gallon capacity tank, which is a standard and practical size for many recreational vehicles and small cabins. The tank itself is constructed from porcelain-lined steel, a critical feature for long-term durability and corrosion resistance. Complementing this is a replaceable anode rod, an essential component for further protecting the tank from corrosive elements, extending its lifespan significantly. The unit offers two primary heating methods: a 1440-watt Incolloy electric element providing a recovery rate of 6 gallons per hour, and a propane burner system. When used simultaneously, the combined gas and electric power achieve an impressive 16.2 gallons per hour recovery rate, a specification that truly sets it apart. It features a convenient exterior gas line connection for easy hookup and a one-piece, die-formed metal control housing that shields the sensitive internal controls from environmental factors like dust and moisture.

The 1440-watt electric element is a good balance between recovery speed and electrical draw, making it manageable even on moderate campground power. The 6-gallon per hour recovery on electric-only is respectable for typical overnight use or when only shore power is available. However, the real magic happens when you engage the propane alongside the electric element. This dual-fuel capability is a game-changer for situations demanding rapid hot water replenishment, such as when multiple people are showering back-to-back or after a busy day of activities. The exterior gas line connection simplifies installation and maintenance, avoiding the need to access the unit’s interior for basic propane hookup. Finally, the robust control housing speaks to Suburban’s understanding of the demanding environments these units often operate in.

Performance & Functionality

In terms of its primary job, delivering hot water, the Suburban Mfg Sw6Del with H 6 Gal Dsi/Elec performs exceptionally well. The advertised 6 gallons per hour recovery rate on electric alone is achievable and sufficient for light use. However, the standout feature is undeniably the 16.2 gallons per hour recovery when both gas and electric are engaged. This is not just a marginal improvement; it’s a transformative capability for active users. We ran this unit through back-to-back showers without issue, a feat that would have left older, single-fuel heaters struggling to keep up. The electronic ignition system is reliable, firing up the propane burner quickly and consistently. The temperature control dial offers a good range, allowing for everything from lukewarm to scalding hot water, though it’s advisable to use the lower settings to conserve energy and prevent scalding.

The unit excels in its primary function, providing ample hot water even under high demand thanks to its dual-fuel system. Its fast recovery rate is its most significant strength, eliminating the common frustration of waiting for water to reheat. One minor observation is that the electric-only recovery, while decent, isn’t as rapid as some might expect if they’re used to the combined power. It serves its purpose for slower days but doesn’t match the urgency of the gas-electric synergy. This is a trade-off inherent in managing electrical loads, but the option to switch to the powerful dual-fuel mode negates this as a major drawback. Overall, this water heater meets and often exceeds expectations for performance, particularly in its ability to deliver hot water rapidly.
