Buying Guide: What To Consider When Choosing an RV Electric Water Heater
- Size and capacity: How many fixtures typically need hot water at the same time? Smaller units (2.5–8 gallons) heat quickly but may run out fast with multiple users.
- Power requirements: All listed units run on 110–120V AC. Confirm the RV’s electrical system can supply the continuous load without tripping breakers.
- Installation location: Under-sink vs. point-of-use placement affects space, fittings, and plumbing routing. Measure clearance before purchase.
- Thermostat control: A precise thermostat helps maintain comfortable water temperatures and improves energy efficiency.
- Material durability: Stainless steel tanks resist corrosion and leaks. Look for certifications (CE, ROHS, FCC) when available.
- Safety features: Inlet/outlet insulation, high-temperature protection, and leak safeguards reduce risk in compact spaces.
- Warranty and service: Longer warranties and straightforward parts availability support reliable RV use over seasons of travel.
