Buying Guide: Key Purchase Considerations for Fifth Wheel Hot Water Heaters
- Fuel type and availability: Tankless models commonly use propane but many offer electric or dual-fuel options. Consider your propane access at campsites and whether you have reliable electrical hookups for electric modes.
- Water heating capacity: Tank heaters provide a stored supply (often around 6–10 gallons), while tankless units heat on demand. If you have multiple occupants or long showers, tankless models with higher GPM (gallons per minute) are preferable.
- Power requirements: Electric elements need shore power or a generator. Tankless units often run on DC or AC power, but many require 12V systems and wiring compatible with your RV’s electrical panel.
- Installation space and fit: Check the door opening size (often 12×12 or 15×15 inches) and cutout dimensions to ensure they align with your fifth wheel’s existing cabinet spaces or exterior compartments.
- Maintenance and durability: Porcelain-lined tanks resist corrosion but require anode rod maintenance. Tankless systems emphasize high-grade heat exchangers and robust control boards; look for certifications (CSA, CE) and warranty coverage.
- Altitude performance: If you travel to high elevations, choose models rated for high-altitude operation to avoid performance drops.
- Temperature control: Precise thermostats, mixing chambers, and remote control options help maintain a comfortable shower temperature and prevent scalding during multi-user use.
- Safety and reliability: Look for features such as flame failure protection, automatic gas shut-off, overflow protection, and clear fault code displays for troubleshooting.
When comparing options, consider your typical usage patterns, the number of occupants, and how often you camp off-grid. Tankless heaters save space and provide endless hot water but may require more careful sizing and venting considerations. Tank models offer simplicity and a familiar feel, with the trade-off of a finite hot water reserve. A dual-fuel setup can offer the best of both worlds for travelers who frequent varied power environments.
