My Buying Guides on Girard Tankless Rv Water Heater

When I decided to upgrade my RV’s water heating system, I quickly found that the Girard Tankless RV Water Heater was a popular choice among fellow travelers. After using one myself, I wanted to share my buying guide to help you make an informed decision.

Why I Chose a Tankless Water Heater for My RV

One of the biggest advantages I found with tankless water heaters is the endless hot water supply. Unlike traditional tank heaters, which run out after a certain amount, the Girard tankless model heats water on demand. For long showers or multiple uses throughout the day, this was a game-changer.

Key Features I Looked For

  • Compact Size: Space in an RV is precious. The Girard model is compact and mounted easily in tight areas, which was perfect for my limited space.
  • Energy Efficiency: I wanted something that wouldn’t drain my battery or propane too quickly. The Girard heater’s efficient design helped keep my energy consumption low.
  • Easy Installation: Since I like DIY projects, I appreciated that Girard provides clear instructions and the unit is designed for straightforward installation.
  • Durability: RV adventures mean exposure to vibrations and movement. The Girard heater felt sturdy and built to withstand the rigors of travel.
  • Heating Capacity: I checked the flow rate (measured in gallons per minute) to ensure it could supply enough hot water for my needs without delays.

What to Consider Before Buying

  • Power Source: Girard heaters typically run on propane with electric ignition. Make sure your RV is equipped to handle this.
  • Water Pressure Requirements: The unit needs a minimum water pressure to operate efficiently. I verified my RV’s water pump met these specs.
  • Climate Conditions: If you travel in freezing temperatures, consider the heater’s freeze protection features.
  • Budget: While Girard units are pricier than some basic water heaters, the long-term savings and convenience justified the investment for me.

My Installation Tips

  • Always turn off propane and water supplies before starting.
  • Follow the manufacturer’s wiring and venting guidelines closely.
  • Use proper venting to avoid exhaust buildup inside the RV.
  • Test the system thoroughly for leaks and proper ignition before relying on it fully.

Maintenance and Troubleshooting

I perform regular checks on the venting system and clean any sediment buildup to keep performance optimal. If the heater fails to ignite, it’s often due to propane supply issues or clogged vents, so I recommend keeping these in mind.

Final Thoughts

The Girard Tankless RV Water Heater transformed my camping experience by giving me reliable hot water anytime I needed it without taking up much space or draining resources. If you value convenience, efficiency, and compact design, this heater is definitely worth considering. Just make sure to assess your RV’s compatibility and installation requirements before purchasing.
