Buying Guide: Key Considerations For Choosing Your 65k BTU RV Propane Heater

When selecting a 65,000 BTU propane tankless water heater for an RV, consider the following:

  • Hot water demand: Evaluate your typical GPM needs for showers, kitchen, and outdoor use. Higher GPM means more powerful models are preferable.
  • Altitude readiness: If you travel to high elevations, ensure the unit is rated for high-altitude operation and has a documented maximum altitude.
  • Power source: Most units run on propane with 12V controls. Confirm your RV’s battery capacity and alternator or generator availability to support the unit’s electronics.
  • Installation size and door compatibility: Check the required opening dimensions and whether optional door kits are needed for your RV model.
  • Remote monitoring: Some models offer real-time gas usage, voltage, and flow rate, helping optimize efficiency and propane consumption.
  • Safety features: Look for pressure relief valves, CSA/ANSI certifications, and built-in safety shutoffs for reliable operation on the road.
  • Replacement compatibility: If you’re upgrading an existing RV heater, verify if the new unit fits the standard openings and can replace popular brands with minimal door modification.
  • Maintenance access: Consider how easy it is to service and clean the heat exchanger and burner area during trips.
