Buying Guide: Portable RV Water Heaters
What capacity do you need?
Consider the hot-water demand per shower and whether you’ll run multiple fixtures. 1.58 GPM is common for many 6L units, while 2.11 GPM or higher is preferred for faster showers or multiple users.
Propane vs. electric or dual power?
Propane models are ideal for off-grid RV travel where hookups are limited. Electric or hybrid units are better where shore power is reliable. If off-grid, ensure you have safe fuel storage and venting.
Portability vs. performance
Compact units are easier to transport but may deliver lower flow. Heavier units with bigger BTU ratings provide hotter water faster but are less convenient to move.
Safety features to look for
Six-in-one protections (overheat, dry burn, anti-freeze, high pressure, flame failure, low-water protection) offer reliable protection in outdoor environments. CSA or CSA-approved regulators add local compliance confidence.
Installation considerations
Check for required gas lines, venting, and water inlet compatibility. Some units include hoses, regulators, and adapters; others require separate purchases. Verify the power source (12V or battery bank) for pump-equipped kits.
Maintenance and longevity
Regular inspection of connections, regulators, and seals helps prevent leaks. Clean screens and ensure proper winterizing if you store your RV for extended periods.
FAQ
- Do I need a dedicated propane tank for these heaters? Most units use a standard propane supply; confirm compatibility with your tank size and regulator before use.
- What water pressure is required to start these heaters? Many models begin at around 2.5 to 3 PSI, though some can start at slightly higher or lower pressures depending on the design.
- Can these heaters be used indoors? These units are designed for outdoor or vented-use scenarios; never operate in enclosed spaces without proper ventilation and exhaust.
- Is a battery or power source required for all models? Some kits include 12V pumps; others are purely propane. Check the product specs for power needs and consider a backup battery plan for off-grid setups.
- Which model is best for a family RV shower? For higher flow needs, TOPWISH or similar 8L units generally offer stronger performance, but ensure your RV’s capacity to handle the load and gas supply.
- Are these units CSA-certified? Several listed options provide CSA or equivalent safety certification, which is important for reliable, compliant operation in the US and Canada.
