Suburban Mfg Heating

Suburban Mfg: The Gold Standard in RV Heating

When it comes to keeping your RV, camper, or motorhome warm in cold-weather conditions, few names carry more credibility than Suburban Mfg. As one of the most recognized names in the RV appliance industry, Suburban has spent decades engineering propane furnaces built specifically for the unique demands of life on the road — compact spaces, limited power budgets, and the need for reliable ignition no matter how remote the campsite.

Suburban's heating product lineup centers on two flagship furnace families: the SF-Q Series and the NT Series, each optimized for different RV sizes and installation scenarios. Together, they cover a wide range of heating needs from small truck campers to full-size motorhomes and park models.

SF-Q Series: Low-Profile Power for Mid-Size to Large RVs

The SF-Q Series is engineered for maximum heating performance in a remarkably slim, ducted package. With capacities ranging from 20,000 to 40,000 BTU/h, these furnaces deliver serious warmth without demanding oversized cabinet space. At just 7.5 inches tall, the SF-Q can be tucked into areas that might otherwise go unused, giving RV designers and retrofitters exceptional installation flexibility. All SF models share identical cabinet dimensions and are built around quiet stainless steel burners, sealed forced-draft combustion, automatic direct spark ignition, and impressively low amp draw — a critical consideration when you're relying on a 12V house battery system. Multiple duct connection choices (top, front, side, and bottom) mean the SF-Q adapts to virtually any floorplan.

NT Series: Time-Tested Ducted and Direct-Discharge Heating

The NT Series represents Suburban's proven workhorse line, offering superior ducted heating in a uniform cabinet size that simplifies installation flexibility across many RV makes and models. NT models run on 12-volt DC power and are available in capacities from roughly 16,000 to 40,000 BTU/h. The NT-SE direct discharge variants eliminate ductwork entirely, delivering heated air straight into the living area — ideal for zone heating in compact trailers and truck campers. NT-S ducted models provide more even heat distribution for larger coaches, and two or more units can even be combined for multi-zone heating. All NT models feature energy-saving solid-state electronic ignition and sealed forced-draft combustion for safe, clean operation.

Why Suburban's Furnace Design Matters

The sealed forced-draft combustion system that appears across Suburban's furnace lines is more than a convenience feature — it's a fundamental safety design. By drawing combustion air from outside the RV and expelling exhaust externally, the system prevents harmful gases from building up inside the living space. Combined with direct spark ignition, stainless steel burners, and easily removable cabinet housings for straightforward maintenance, Suburban furnaces are designed to be as owner-friendly as they are dependable.

Whether you're replacing an aging unit or outfitting a new build, Suburban Mfg's heating products offer the proven performance and parts availability that RV owners and technicians have relied on for generations.
