Can the Fogatti RV FOGATTI FS10B1S provide a 10-minute shower without a flame out?

You must ensure your propane supply provides sufficient pressure to the heat exchanger—the component that transfers heat from the burner to the water—to maintain this output. Verify your propane regulator is functioning correctly before installation.

Fogatti FS10B1S flow rate requirements and high altitude performance

This tankless water heater, which is a compact unit that heats water instantly as it flows through pipes, maintains a maximum flow rate of 3.6 GPM. We selected this model for our review because it meets the high-altitude requirements while maintaining a high flow rate. If your RV plumbing provides less than the required pressure, the unit may shut down for safety to prevent a flame out. A mismatch between your plumbing pressure and the unit’s requirements can result in a costly return or a failed installation.

What to Check Before Buying the FOGATTI FS10B1S

Confirm these technical requirements to ensure the unit performs as expected in your specific RV setup:

Review the technical details in our FOGATTI FS10B1S spec breakdown.

• Verify your propane source provides enough pressure to sustain the 66,000 BTU output.
• Measure your internal plumbing to ensure it can support a 3.6 GPM flow rate.
• Confirm your 12 Volts (DC) power supply can provide 46 Watt-hours of power.
• Check that your mounting area accommodates the 15″W x 15″H footprint.
• Ensure your propane regulator is rated for the required pressure to prevent the burner from cycling.

Evaluating the FOGATTI FS10B1S Alternatives

The FOGATTI FS10B1S is suited for users who prioritize high-altitude performance and high flow rates over basic heating. If you require a unit with a higher flow rate than 3.6 GPM, you may need to look at larger systems that offer higher BTU outputs. Buyers with very low water pressure requirements might find simpler, lower-output models sufficient for their needs. This model sits in a middle ground that balances power for high-elevation camping with a standard flow rate for comfortable showering.

Owners of large rigs should explore the best hot water for truck camper setups.

Choose the FOGATTI FS10B1S if you need a reliable heater for high-altitude travel that can maintain a steady flow of hot water. If you require a flow rate exceeding 3.6 GPM for multiple simultaneous fixtures, consider a higher-capacity tankless model.
