Suburban Mfg Water Heaters

Suburban Mfg Water Heaters: Reliable Hot Water for Every RV

When it comes to dependable hot water on the road, Suburban Mfg has long been one of the most trusted names in the RV industry. Their water heater lineup is purpose-built for the demands of travel trailers, fifth wheels, and motorhomes — where space is tight, energy sources vary, and consistent performance is non-negotiable.

The Suburban Advantage Lineup

Suburban's flagship offering, the Advantage line, is designed to cover virtually every RV application. The Suburban Advantage line of RV water heaters includes high recovery gas, gas/electric combination, gas/electric/motor aid, and tankless continuous models — with sizes and features to match the requirements of almost any RV. Whether you're outfitting a compact weekend camper or a full-time motorhome, there's a Suburban unit sized and configured for the job.

Their lineup covers gas-only, gas-electric, and DSI models in tank sizes from 6 to 16 gallons, giving you options whether you are doing a like-for-like replacement or upgrading to a higher-capacity unit.

Key Technologies and Features

What sets Suburban water heaters apart from the competition goes deeper than tank size. Suburban uses a porcelain-lined, steel (outer surface) water heater tank with an anode rod that absorbs the electrolytic action — the same proven approach used in residential water heaters, adapted for the road. When a Suburban porcelain-lined tank is properly maintained, tank life may double or triple its three-year limited warranty; in addition, every Suburban tank is pressure tested twice during the manufacturing process to ensure its integrity.

• Direct Spark Ignition (DSI): DSI allows you to remotely ignite the pilot from inside your camper or RV, saving time and effort while helping you avoid poor weather conditions. Select electronically controlled water heaters are perfect for adverse weather with a remote switch that conveniently lights the heater from inside.
• Gas/Electric Combination: With gas-electric models available, you can increase your recovery time and performance — recovering up to 6 gallons of hot water per hour for minimal hot water downtime.
• Re-ignitor Technology: The re-ignitor is used for relighting the pilot in the event it goes out , ensuring that heat recovery stays consistent without manual intervention.
• Copolymer Heat-Retention Jacket: A heat-retaining copolymer jacket is fitted to keep the heat close, ensuring none escapes — improving efficiency and reducing energy consumption.
• Motor Aid Models: Available on select units, motor aid assist provides an additional boost for faster heating, ideal for larger groups or high-demand use.

Broad Compatibility and Easy Replacement

Suburban is one of the most established names in RV water heaters, with units found in a wide range of travel trailers, fifth wheels, and motorhomes. This widespread adoption means that replacement is typically straightforward — existing cutout dimensions and connection points are often compatible with newer Suburban models. If you are replacing an existing Suburban unit, check your current model number and tank size, as well as your RV's cutout dimensions, to confirm the right fit before ordering.

With over 53 water heater products in the Suburban Mfg catalog, finding the right unit — whether it's a compact 6-gallon gas model or a high-capacity 16-gallon DSI gas/electric combo — is a matter of matching your RV's specs to the right configuration.
