Buying Guide: Key Considerations For RV Tankless Water Heaters
- Volume needs: How many gallons per minute (GPM) do you require for showers, dishes, and faucets? Choose higher BTU and GPM for larger families or longer showers.
- Power source compatibility: Ensure the unit matches your RV’s power system (propane vs electricity vs 12V DC). Tankless units often rely on propane but may offer DC options.
- Altitude performance: If you frequently camp at high elevations, look for high-altitude support and robust ignition systems.
- Installation fit: Confirm cutout dimensions (15″×15″ is common) and fit with your current RV heater compartment. Consider door color and panel options if aesthetics matter.
- Temperature control: Precise temperature regulation minimizes scald risk and prolongs water heater life. Some models offer ±1°F accuracy and automatic flame adjustments.
- Reliability features: Anti-freeze capability, leak resistance, and seasonally adaptive flame control can improve off-grid reliability.
