Buying Guide: Key Purchase Considerations
What fuel options fit my RV lifestyle? Tank heaters typically run on propane gas with optional electric heating; tankless models often rely on propane and may require electrical support for certain features. Consider your typical camping setups and whether you travel to areas with limited gas or electricity access.
What tank size or flow matters? Tank heaters come in 6–10 gallons; tankless units specify GPM. If you have multiple users, a larger storage or higher GPM can minimize wait times and temperature fluctuations.
How important is maintenance? Heaters with replaceable anode rods or straightforward drain ports simplify long-term care and corrosion protection. Tankless units may require careful installation and venting; factor in space and professional installation needs.
Which installation considerations matter? Check cabinet dimensions, available door openings, and venting requirements for tank-style versus tankless designs. High-altitude operation is a plus for mountainous travel, as some models are optimized for low-temperature conditions.
Power availability and compatibility: Tank heaters with optional electric elements demand sufficient electrical supply. Tankless options may require dedicated circuits or remote controls. Confirm your coach’s power capacity before choosing a model that uses electric heat or remote control features.
FAQ
- What is the difference between tank and tankless RV water heaters?
Tank heaters store hot water in a tank for immediate use, while tankless units heat water on demand, saving space and reducing standby heat loss. - Can I mix gas and electric heating on an RV water heater?
Some models offer dual heating (gas with optional electric). This provides flexibility when one fuel source is unavailable. - What maintenance does an anode rod require?
An anode rod should be inspected and replaced if corroded to protect the tank from rust and extend lifespan. - Will a larger tank fit in my RV cabinet?
Check the interior cabinet dimensions and door openings. Some models require more space or a different installation approach. - Do high-altitude RV heaters work well in mountains?
Many models advertise high-altitude performance, but verify installation clearances and venting for your climate and elevation.
