Best RV Water Heaters

A cold shower after a long hike is a quick way to sour a trip, and the small tank heaters in many rigs run out of hot water before you have rinsed the shampoo out. Upgrading, whether to a larger tank or an on-demand tankless unit, means reliable hot water for showers and dishes without the anxious countdown. Here we compare RV water heaters across tank and tankless designs. We look at recovery time and endless-hot-water capability, propane and electric fuel options, water and battery draw for off-grid use, and how the physical size and mounting match common RV openings so the upgrade fits the space you already have.
