What the AI looks for in RV Water Heaters, Parts & Accessories

Tank brand and material
Identify the heater from its data plate before buying anything. Suburban tanks are porcelain-lined steel and need an anode rod. Atwood/Dometic tanks are aluminum and use a plain drain plug. Most parts, including anodes, drain plugs, elements and boards, are not interchangeable between the two families.
Model and series from the data plate
Match parts to the exact model and series, including the ignition type (pilot or DSI) and whether it is gas-only or gas/electric. Control boards, gas valves and thermostats differ between series that look the same.
Fuel and power
Match the ignition type, voltage and element wattage exactly. A mismatched element or board can fail to heat or overload the circuit.
Winterizing provisions
The system should have a bypass valve kit so the tank can be isolated when antifreeze is pumped through. Without a bypass, you fill a 6 or 10 gallon tank with antifreeze, and a tank left with water in it can freeze and crack.

Brands that matter

  • Suburban: Porcelain-lined steel tanks; the anode rod is a routine wear part.
  • Atwood / Dometic: Aluminum tanks with no anode; the older Atwood line now sells under Dometic.
  • Girard: Tankless RV water heaters.
  • Truma: AquaGo tankless units.
  • Furrion: Tankless units found on many newer trailers.
  • Camco: Anodes, drain plugs, tank rinsers and bypass kits.

What to avoid

  • Putting a Suburban anode rod in an aluminum Atwood/Dometic tank.
  • Buying parts by appearance instead of by the data plate model number.

Questions

Does my RV water heater need an anode rod?

Only if it is a steel-tank unit such as a Suburban. Aluminum Atwood/Dometic tanks use a drain plug with no anode.
