The Furrion FWH (Furrion Water Heater) tank line is the brand's conventional RV tank water heater lineup — pre-installed in many Class B+ motorhomes, mid-tier travel trailers, and compact fifth wheels. FWH models compete directly with Suburban and Atwood/Dometic tank water heaters in the standard RV market.
FWH lineup
- FWH-6G: 6-gallon, gas-electric combination — most common size for mid-tier RVs
- FWH-10G: 10-gallon, gas-electric combination — larger trailers and motorhomes
- FWH-2.4G: 2.4-gallon compact, fits very small bay openings in tiny trailers
What distinguishes FWH from competitors
Furrion's positioning in the RV appliance market emphasizes modern aesthetics and integration with other Furrion equipment (refrigerators, AC units, generators). FWH water heaters use modern control electronics, often integrate with Furrion's RV control panels, and have cleaner exterior design than legacy Suburban or Atwood units.
Operational features
- Quick-recovery design: propane burner sized for fast tank reheat after depletion
- Dual fuel (gas + electric): standard on most FWH models, allows electric-only operation on shore power
- Digital control: setpoint adjustment, basic diagnostic display
- Improved insulation: reduces standby heat loss vs older RV designs
FWH vs Suburban (the dominant competitor)
Suburban dominates the RV water heater parts ecosystem — anode rods, thermocouples, gas valves are universally stocked at any RV dealer. FWH parts are Furrion-direct or specialty RV retailers. For long-term ownership, Suburban's parts network is the safer choice. For factory-installed FWH replacement (preserving brand consistency), FWH is the natural pick.
FWH vs Dometic (acquired Atwood)
Dometic has broader parts availability than Furrion through Dometic's authorized RV service network. FWH has cleaner aesthetics in newer RV builds. Functionally similar for typical use; choose by parts ecosystem and design fit.
Common service issues
- Anode rod replacement: annually or per Furrion's recommended schedule
- Flame sensor cleaning: bi-annually for propane reliability
- Thermocouple: typical replacement at year 4–6
- Element replacement: typical at year 6–10 with hard water exposure
- Control board: rare but expensive when it fails ($150–250 OEM)
Installation specifics
FWH installs in standard RV water heater bay openings with bay dimensions that match Furrion's spec. Connections: propane (3/8" flare typical), 120V AC for controls and electric mode, cold water inlet (1/2" garden-hose or PEX), hot outlet (1/2" PEX). Mounting bracket integrated into the unit's frame.
Winterization
FWH requires standard RV water heater winterization for any storage in below-freezing temperatures. Procedure follows the Furrion-specific bypass valve configuration (verify your bypass valve count and position in the FWH manual — some FWH models use a slightly different bypass scheme than Suburban/Atwood).
Lifespan
FWH tanks in typical RV service last 8–12 years. Tank wall corrosion is the eventual failure mode; properly maintained units with annual anode replacement and proper winterization achieve the upper end of that range.
