<h3>About Suburban Manufacturing</h3><p><strong>Suburban Manufacturing</strong> has been a cornerstone of the RV industry for over 75 years. <a href="/7593-suburban-mfg">Suburban Mfg</a> traces its roots back to 1947, when it began as the Hunt Heater Company, producing small gas space heaters in Dayton, Tennessee. A pivotal moment came when a customer asked whether one of Suburban's greenhouse heaters could be adapted to run on 12V for use in a motorhome — and the RV-focused legacy of the brand was born. Today, Suburban is headquartered in the same Dayton, Tennessee community it has called home for decades, operating out of a facility that spans more than 300,000 square feet.</p><p>In 1998, Suburban joined the <strong>Airxcel</strong> family of brands, which has grown into the leading designer, manufacturer, and distributor of critically functional products for the RV industry. That partnership gave Suburban the resources to continuously refine and expand its product line while maintaining the hands-on manufacturing quality that built its reputation. Suburban's engineers have pioneered a long list of RV industry firsts — from space-saving, horizontally vented gas heating systems and solid-state spark ignition technology to efficient DC furnace motors and glass-top ranges that double as counter space when not in use.</p><h3>What Suburban Makes</h3><p>Suburban's core product lineup covers the essential comfort systems that RV travelers depend on every day. The brand is perhaps best known for its <a href="/7593-suburban-mfg-heating-200526">RV heating solutions</a>, including a comprehensive range of ducted furnaces and wall heaters engineered specifically for the space constraints and power demands of motorhomes and travel trailers. Suburban furnaces are designed to deliver reliable warmth using propane, with efficient DC blower motors that minimize battery draw — a critical factor for off-grid campers.</p><p>Beyond heating, Suburban has long been a trusted name in RV kitchen appliances. Their <a href="/7593-suburban-mfg-stoves-cooktops-201021">stoves and cooktops</a> are built with the unique requirements of RV galleys in mind: compact dimensions, durable construction, and propane-compatible burners that perform reliably on the road. Suburban has also expanded into <a href="/7593-suburban-mfg-stoves-cooktops-202596">outdoor cooking</a>, offering cooktops and cooking appliances designed for the camp kitchen experience outside the coach — including griddles and other galley accessories inspired by contemporary European design and manufactured in America.</p><p>Most of Suburban's product line is backed by a <strong>2-year limited warranty</strong>, reflecting the brand's confidence in its own manufacturing standards. Each product goes through a rigorous series of quality and safety tests before leaving the Dayton facility — a commitment that has made Suburban a preferred OEM supplier for many of the largest RV manufacturers in North America.</p><h3>A Legacy of Innovation</h3><p>Suburban's influence on modern RV design is difficult to overstate. The company helped pioneer the glass-top range, which transformed compact galley kitchens by providing valuable counter space when burners aren't in use. More recently, Suburban has pushed into all-in-one solutions: their <em>RV One</em> system combines an on-demand water heater and NT furnace into a single unit engineered for the growing segment of compact and lightweight travel trailers. With a track record of listening closely to the needs of RV builders and end users alike, Suburban continues to set the standard for what RV appliances can be.</p>

Product Details

The Suburban SW12DEL 12-gallon RV water heater delivers reliable hot water performance for recreational vehicles with dual fuel flexibility. This direct spark ignition model operates on both LP gas and 120V AC electric power, allowing you to choose the most convenient energy source whether dry camping or connected to shore power at the campground.

Key Features:

  • 12-gallon porcelain-lined steel tank with replaceable anode rod for long-lasting durability
  • Direct spark ignition (DSI) system eliminates the need for pilot light maintenance
  • 12,000 BTU/hour gas burner with 10.1 gallons per hour recovery rate
  • 1440-watt Incoloy electric heating element with 6.1 gallons per hour recovery rate
  • Combined gas and electric operation provides rapid 16.2 gallons per hour recovery
  • 12-volt relay switch enables interior control of both gas ignition and electric heating
  • Foam insulation maximizes heat retention and energy efficiency
  • One-piece die-formed housing protects controls while providing easy access
  • Fits standard 16-3/8" x 16-3/8" x 20-1/4" cutout dimensions

The porcelain-lined steel tank construction resists corrosion from heated water, while the included anode rod absorbs electrolytic action to extend tank life. Each tank is pressure tested twice during manufacturing to ensure integrity. The compact design uses the same door and cutout dimensions as Suburban 10 and 16 gallon models, making upgrades straightforward. Note that the access door is sold separately.

Specifications: 16-7/32" H x 16-7/32" W x 22-1/4" D | 48 lbs empty weight | Model designations: SW12DEL, 5148A, 5248A, 5148F | Backed by 2-year limited warranty and 3-year tank limited warranty
