Buying Guide for RV Propane Heaters
When choosing an RV propane heater, several factors influence the best fit for your needs. Understanding these criteria helps in selecting a unit that provides efficient hot water delivery with safety and convenience.
Heating Capacity and Flow Rate
BTU output dictates how quickly and effectively a heater can warm water. Higher BTU models, typically 55,000 to 65,000, deliver more instantaneous heat and support multiple simultaneous hot water uses. Flow rate, measured in gallons per minute (GPM), determines how much hot water is available at once. For families or frequent RV users, devices offering over 2 GPM are preferable.
Tankless vs. Tank Models
Tankless propane heaters provide instant hot water on demand and save space, making them ideal for RV use. They prevent the energy waste and water limitations common in traditional tank heaters. However, tank models may provide a buffer supply which some users find convenient for quick repeated use.
Installation and Compatibility
Check your RV’s water heater opening size and model compatibility. Many tankless heaters come with optional door kits to fit common RV dimensions (usually around 15″x15″ or 15″x18″). Ease of installation and retrofit capability can save time and cost, especially if upgrading from a traditional heater.
Power Source and Efficiency
Most RV propane heaters operate on 12V DC, using propane gas for heating, which ensures independence from shore power. Look for models with high thermal efficiency (around 85% or more) to reduce propane consumption and costs. Some also provide freeze protection and altitude adaptability for better performance in extreme environments.
Safety and Additional Features
Safety features such as automatic shutoff timers, anti-scald protection, and diagnostic error codes enhance reliability on the road. Advanced controls like remote operation and thermostatic temperature settings add convenience. Dual water outlets for outdoor washing increase functionality for campers and pet owners.
