Buying Guide: Key Purchase Considerations For RV On-Demand Hot Water
- BTU and flow rate: Higher BTU and GPM improve shower comfort and simultaneous use, but may increase propane consumption. Match BTU to your typical water demand and RV size.
- Altitude performance: If you travel in mountains, choose models rated for high altitude to prevent heat loss or unreliable operation.
- Fuel source compatibility: Propane is common for RVs, but some units offer electric or hybrid options. Ensure electrical and gas hookups align with your setup.
- Door opening and cabinet fit: Most units use a 12″ x 12″ to 15″ x 15″ door footprint. Measure available space and venting clearance before purchasing.
- Remote control and monitoring: A well-placed remote or digital display simplifies temperature adjustments while on the move.
- Installation considerations: Venting, piping connections, and space for condensate and drainage affect installation time and cost. Some models retrofit easily into existing door openings; others may require modifications.
- Maintenance and durability: Look for corrosion-resistant heat exchangers and reliable fans to withstand RV vibrations and varying climates.
- Warranty and service: A solid warranty and accessible service channels are important for RV components exposed to travel stress.
- Energy efficiency: Staged combustion and smart controls help regulate heat and propane use, extending propane life during long trips.
- Replacement vs upgrade: If your current system is older or undersized, upgrading to a higher BTU model with remote control can improve performance without a full retrofit.
Note: Installation requirements vary by model and RV layout. Always refer to the manufacturer’s installation manual and consult a professional if you’re unsure about venting, gas lines, or electrical connections.
