Buying Guide: Propane RV Tankless Water Heaters
When choosing an RV tankless water heater, several practical factors determine suitability for your camper, travel style, and typical water demand.
- BTU and flow rate considerations: Higher BTU generally yields faster hot water. For large households or long showers, aim for 60,000 BTU+ with 3.5–4.0 GPM. For compact setups or occasional use, 40,000–50,000 BTU with 1.5–3.0 GPM can suffice.
- Altitude readiness: If you frequently drive through mountains, look for units marketed as high-altitude ready or with features like oxygen-free copper heat exchangers and staged combustion.
- Installation space and compatibility: Check door size openings (e.g., 15 × 15 inches) and mounting options to ensure your RV can accommodate the unit without extensive remodeling.
- Power and control: Most models run on 12V DC; consider whether your RV’s battery and wiring can support installation. Some units offer remote controls for easier operation.
- Safety features: CSA certification, anti-freeze protection, flame-out protection, and overheat protection help ensure safe operation in varied climates and long trips.
- Portability vs. fixed installation: Portable models suit weekend campers and off-grid ventures, while fixed units provide consistent comfort for full-time RV living.
