Fogatti Tankless RV Water Heaters

What sizes do Fogatti tankless RV water heaters come in?

Fogatti tankless units are sized by BTU output and gallons-per-minute flow rather than tank capacity. The InstaShower line covers 42,000 to 55,000 BTU models with flow rates between 1.5 and 2.9 GPM, which is enough hot water for back-to-back showers without a recovery wait. If you prefer a conventional tank-style unit, compare options in our 10 gallon RV water heater collection.

Will a Fogatti tankless water heater fit my existing RV water heater opening?

Most Fogatti InstaShower models are designed to drop into the standard 12" x 12" or 16" x 16" cutout left by a Suburban or Atwood tank heater, with optional adapter doors for the larger opening. Always measure your current opening and confirm the gas line, 12V power, and water line locations before ordering. If you need help confirming fitment, call or text our team at 817-984-1852.

Do you carry replacement parts for Fogatti tankless water heaters?

Yes. We stock control boards, igniters, door assemblies, and flow sensors for the Fogatti InstaShower line. Have your model number and serial label handy when ordering so we can match the correct revision. For winter storage, pair your unit with a kit from our RV winterizing kits collection to prevent freeze damage to the internal heat exchanger.

How does a Fogatti tankless heater compare to a traditional 6 or 10 gallon RV water heater?

A tankless unit heats water on demand, so you get continuous hot water as long as the propane and 12V power hold up, and you save roughly 30 to 40 pounds of stored water weight. A tank heater recovers faster on a cold start and works without modulating gas flow, which some users prefer in cold climates. Browse the RV electronics collection if you need a thermostat or controller upgrade to go with the swap.
