Best Electric Tankless Water Heater For Rv (2024 Update)

Are you an RV owner looking to upgrade your water heater? Installing an electric tankless water heater can be a game-changer, providing endless hot water on demand without the constraints of a tank. But with so many options on the market, how do you determine which is the best electric tankless water heater for your RV?

When researching tankless water heaters, there are a few key factors to consider. First, look at the unit’s flow rate – how many gallons per minute it can heat. A higher flow rate means more hot water at once. Next, examine the power requirements. Some models require a dedicated 50-amp circuit, while others can run on a standard 30-amp hookup. Also, check the activation flow rate – the minimum water flow needed to turn the heater on. The lower this number, the more responsive the unit.

You’ll also want to consider size and weight constraints specific to RVs. Will it fit in your existing space? How much does it weigh? A more compact, lightweight model may be preferable. Finally, look for safety features like automatic shut-off and built-in freeze protection. An ideal unit will be durable enough to handle life on the road while providing endless hot showers whenever you need them.
