Buying Guide: How To Choose The Right Camper Water Heater
Key questions to guide your selection:
- What is my power source? If you have 110V shore power, tankless electric models are convenient. If you rely on propane or limited power, consider propane-powered or hybrid options.
- What is my water demand? For quick handwashing and sink tasks, 2–4 gallon units may suffice. For showers, plan for larger tanks or higher-flow options.
- Where will it install? Measure available space under the sink or in a cabinet. Tankless units require space for connections and ventilation only if applicable.
- What safety features are required? Look for leak protection, dry-fire protection, and temperature control with a clear display for reliable operation.
- Is altitude a concern? Some RV models are designed to operate at high elevations; verify compatibility if you travel to mountainous areas.
