Specifications side by side

Furrion Tankless Water Heater Picks

The Furrion lineup features two gas-powered units designed for RV use. Both models deliver 2.4 GPM flow rates, ensuring consistent hot water for showers and sinks. They share a white finish, keeping the exterior clean and uniform with standard RV fixtures. The primary difference lies in physical dimensions and specific compatibility features. You should compare the size and weight to match your existing space. The top pick fits a 16.14” x 16.14” door, while the second option uses a standard size. This distinction matters for replacement projects. Choose the Furrion 2.4GPM RV Gas Water Heater if you need Suburban door compatibility. Select the Furrion 2.4 GPM Gas Tankless Water Heater for a straightforward, reliable gas heating solution that prioritizes easy installation over smart features.

Where Furrion Fits

Furrion’s current lineup focuses on compact, white gas units for RVs. Both models provide 2.4 GPM flow, suitable for solo travelers or couples. The top pick features a 16.14-inch square door design, while the second option uses a standard size. You get vibration resistance and straightforward installation. However, the range lacks high-flow options above 2.4 GPM and omits smart features or remote controls. If you need higher capacity or digital connectivity, this brand’s specific models do not offer those specs.

How to Choose the Right Furrion Tankless Water Heater

1. Check Suburban Door Fit

   If your RV has a Suburban-style access door, verify the unit’s dimensions match the opening. The top-rated Furrion 2.4GPM model measures 16.14 inches by 16.14 inches, designed specifically for this common door size. This ensures a clean installation without modifying the exterior panel. The second model uses a standard size, which may not fit every RV cutout. Measure your existing door frame before buying. Proper fit prevents leaks and maintains the structural integrity of your RV wall. Always confirm the exact width and height against your vehicle’s specifications.

2. Consider Flow Rate Needs

   Both Furrion models deliver a 2.4 gallons per minute flow rate. This capacity is suitable for solo travelers or couples using a single showerhead. If you need higher flow for multiple fixtures, this might be limiting. The consistent 2.4 GPM ensures steady hot water for basic hygiene tasks. It is not designed for high-demand scenarios like running a dishwasher and shower simultaneously. Check your showerhead’s flow restriction. Lower flow rates conserve propane and water, which is critical for boondocking. Match the GPM to your typical usage patterns.

3. Verify Gas Compatibility

   Furrion units are gas-powered, requiring a propane or natural gas connection. Ensure your RV has the necessary gas lines and pressure regulators. The models rely on reliable ignition systems for consistent heating. You must have access to a gas source for these units to function. They do not operate on electricity alone. Check your gas valve compatibility. Proper gas pressure is vital for safe operation and efficient heating. If you are converting from electric, plan for the gas line installation. Always follow local RV gas safety codes during setup.

4. Assess Weight and Space

   The top pick weighs 43.8 pounds and measures 12.6 inches wide by 20.8 inches high. This compact footprint fits into tight RV compartments. The second model also prioritizes space efficiency with a standard size. Consider the available storage space for installation. Heavier units may require additional support brackets. Ensure the mounting area can handle the weight. The white finish helps the unit blend with standard RV exteriors. Measure the installation cavity carefully. Proper spacing allows for adequate ventilation and maintenance access. Compact design is key for limited RV spaces.

5. Prioritize Vibration Resistance

   RVs experience constant movement on the road. The top-rated model is noted for vibration resistance, ensuring durable performance during travel. Look for units with sturdy internal components that withstand shaking. The second model focuses on reliable ignition but does not highlight vibration specs. Check for secure mounting options. Vibration-resistant designs reduce the risk of internal damage over time. This is crucial for long-term reliability in mobile environments. Ensure all connections are tight before departure. A robust build quality extends the lifespan of your water heater significantly.
