Buying Guide
What to consider when choosing a camper water heater
- Heat output and flow rate: Higher BTU and GPM mean faster hot water, but check if your RV plumbing and propane system can supply it.
- Fuel type and efficiency: Propane models are common; some units offer better altitude performance or energy-saving features.
- Installation space and dimensions: Measure your RV’s opening and cabinet space to ensure a proper fit with the door size and mounting pattern.
- Altitude and weather performance: If you travel to higher elevations or cold climates, choose heaters designed for high-altitude operation and anti-freeze protections.
- Control and monitoring: LED displays, remotes, and digital thermostats help maintain stable temperatures with minimal effort.
- Maintenance and durability: Consider units with protective features, corrosion-resistant materials, and accessible service components like anode rods or easy drain ports.
- Compatibility and retrofit options: If upgrading an existing RV system, verify door dimensions, venting requirements, and compatibility with other brand components.
How to plan installation without surprises
- Check space for both interior and exterior mounting if dual-outlet models are used.
- Prepare necessary venting, gas supply lines, and electrical connections per manufacturer guidelines.
- Ensure ventilation and inside air quality with appropriate exhaust routing and carbon monoxide safety measures.
