Buying Guide For Choosing The Best RV Heater

When selecting an RV heater, consider your heating needs and space to find the best solution. Here are some important factors:

Heating Type

  • Portable Radiant or Propane Heaters: Ideal for heating living areas, cabins, or small RVs. Look for safety features like auto shut-off and oxygen depletion sensors.
  • Electric Space Heaters: Perfect for use when connected to shore power, providing quiet and controllable warmth without combustion.
  • Tank Heater Pads: Specifically designed to prevent water tanks from freezing. Choose adhesive pads compatible with your tank size.
  • Tankless Water Heaters: Provide instant hot water for showers and kitchen use, saving space and energy compared to tank-based systems.

Power Source and Efficiency

  • Propane Heaters: Convenient for off-grid heating but require ventilation and caution regarding carbon monoxide.
  • Electric Heaters: Efficient and safe indoors but require a reliable power source.
  • Tankless Heaters: More efficient water heating, especially with demand-based operation.

Safety Features

  • Look for heaters with tip-over shut off, oxygen depletion sensors, and overheat protection.
  • Heaters should be certified for indoor use to prevent risks associated with combustion.

Size and Portability

  • Consider the heater’s footprint and whether it fits your RV’s limited space.
  • Portable heaters offer flexibility but may need careful placement.
  • Tank heaters and tankless systems attach directly, saving space.

Altitude Compatibility

  • If you camp at high altitudes, choose heaters designed to operate efficiently above 7,000 feet to avoid shut-offs.

Installation and Maintenance

  • Tankless water heaters may require professional installation but offer low maintenance.
  • Portable heaters and pads are generally plug-and-play with minimal setup.
  • Regularly check and replace components like anode rods in water heaters to avoid corrosion and ensure longevity.

By evaluating the space you need to heat, power availability, and safety requirements, you can select the ideal heater to keep your RV warm and comfortable in any weather.
