Atwood vs. Suburban Propane Hot Heaters -Pilot Light Models

Hi folks,

I have been studying ways to heat water using propane for places with little or no electric/running water. (Cabins, Hunting/Fishing Camps, Barns, ect.) The 'Old-School' RV Propane Water Heaters with no electronics appear to be a good solution. The various portable tank-less models require (waste) too much water in order to function.

Atwood and Suburban still make 6 and 10 gallon propane hot water heaters that uses a pilot light. (That must be lit manually from the outside). These models allow one to conserve water and appear to be KISS simple.

Which Brand to choose? Prices are comparable.
.
The Suburban has a bigger burner, is steel, but requires that the anode be changed.

The Atwood uses an aluminum tank, no anode, and claims that their 'Through Tube' Combustion Chamber makes for a more efficient use of the pilot light for maintaining temperature.

I would really appreciate hearing from the members with 'real-world' experience. The main negative I have read about is that strong winds will blow out the pilot light.

Ease of lighting the pilot light, reliability, parts availability and ease of service?

Something that appealed to me was the option of setting to control knob to 'Pilot' during the day just to keep the water lukewarm for handwashing and then turning the control knob to 'on' just before showers are taken.

Thanks in advance for your comments,

Fred
  • Personally I would use an Atwood 10 gallon pilot only water heater.

    Through Tube Combustion Chamber....... chamber/exhasut runs diagonally from lower right side to upper left side of tank (Suburban's 'U' Tube is stacked directly above each other far right side). Diagonally allows more surface contact.

    Uses 10,000 btu/hr with a 13,2 gallon per hr recovery rate (Suburban 12,000 & 10.2 recovery)

    Aluminum tank (clad with aluminum/zinc alloy) so no anode rod required (Suburban STEEL tank with porcelain lining....cracks/steel needs anode rod)

    Lighter weight unit/smaller size vs Suburban

    Pilot ignition......on both so stand alone operation/no DC needed
    (Only pilot with re-ignition or DSI Units need the DC)
  • I have an Atwood pilot model. There are no wires to the gas valve so no 12V is required.

    It does have a 12V sparker to light the pilot, but I think that was an add-on. It would not be required to run the unit.

    I'm not sure about RV water heaters with pilot lights because my only experience with is with DSI models, but . . .

    I've had plenty of experience with residential gas water heaters with pilot lights. I've never seen one that needed any electricity at all. I see no reason why RV versions with pilot light would necessarily need electricity.

  • I have owned both and found both to be reliable. You mentioned shutting unit to Pilot light only. This feature heated my water really well. In fact I often showered in the evening and was again ready to go the following night unless it was super cold.I full timed for many years doing this
