RV Water Heaters

Match capacity to your RV and usage: small (2–6 gallons) for vans or solo travelers, medium (6–10 gallons) for small to mid-size RVs, and larger tanks for families or extended stays; also check physical dimensions and mounting compatibility with your RV’s compartment

RV water heaters commonly use propane, 120V electric, or a combination (propane with electric backup); choose based on your RV’s hookups and boondocking needs—propane heats off-grid, electric works when shore power is available, and combo units offer flexibility

Look at recovery rate (gallons per hour heated) and stated energy efficiency: higher recovery rates mean faster hot-water replenishment after use, while better efficiency reduces fuel or electric draw; compare specs rather than brand claims to match expected usage patterns

Prices vary by capacity, fuel type, and features; entry-level small units are at the lower end while combo or higher-capacity models cost more; expect a range across the category rather than a single price point, and factor in installation or conversion costs

Verify mounting footprint, venting and flue requirements for gas units, electrical requirements for electric models, and whether professional installation is needed; perform regular maintenance like flushing to remove sediment, checking anode rods if present, and inspecting seals and fittings for leaks

Tankless units provide continuous hot water and save space, but they require sufficient fuel or electric capacity and may have higher upfront cost and more complex installation; evaluate whether your RV’s power/fuel system can support the unit’s peak demand

Confirm thermostatic controls, pressure-relief valves, proper venting for combustion appliances, and certifications like CSA or UL where applicable; ensure controls and emergency shutoffs are accessible after installation
