Buying Guide
Hot water makes RV life easy. Comfort follows you everywhere.
Travelers love the freedom of endless showers and warm dishes. The right RV water heater turns every trip into a home-like journey.
Factors to Consider When Buying an RV Water Heater
-
Type of Heater:
Choose between tank and tankless. Tank heaters store water but run out fast. Tankless heaters give endless hot water on demand. -
Fuel Source:
Most use propane, electric, or both. Propane is strong for off-grid trips. Electric is handy at campsites with hookups. -
BTU Power:
Higher BTU means faster heating. Look for 40,000–68,000 BTU for steady showers. More BTU gives better flow and comfort. -
Flow Rate (GPM):
Measured in gallons per minute. A higher GPM means longer showers and easier dishwashing. Families should aim for 2.5–4 GPM. -
Size & Fit:
Check the door size and space in your RV. Compact designs fit most rigs. Some models offer multiple door options for easy retrofit. -
Altitude Performance:
If you travel in mountains, pick a heater with high-altitude technology. It keeps combustion steady and avoids cold spots. -
Safety Features:
Look for CSA certification, anti-scald protection, and built-in sensors. Safety ensures peace of mind on the road. -
Durability:
Tank models with porcelain-lined steel and anode rods last longer. Tankless units with copper exchangers resist wear and save energy. -
Ease of Use:
Smart remote controls and LED displays make adjusting temperature simple. Quick-fit connectors help with easy installation. -
Energy Efficiency:
Choose heaters with smart combustion or exclusive heat transfer technology. They save propane, electricity, and money.
