The Furrion 2.4GPM Tankless RV Gas Water Heater delivers steady temperatures through its Vortex technology and withstands road vibrations with VibrationSmart components. If you are looking for furrion 2 4gpm tankless RV gas alternatives, you might need a different flow rate, fuel type, or physical size. This unit is a compact 12.8 x 12.6 x 20.75-inch model designed for specific door replacements, but it lacks electric backup heating and offers only a 2-year warranty.

Some options provide higher flow rates for simultaneous use, while others include electric elements for backup heating. You may prefer a lighter unit for easier installation or a model with remote control convenience. Each listed product meets the core requirement of providing hot water for RV use, but they vary in BTU output, dimensions, and power sources to suit your specific travel needs.
Our top pick: Furrion 2.4GPM RV Gas Water Heater.
How these alternatives compare to the Furrion
Suburban 6-Gallon Gas and Electric RV Water Heater
The Suburban 6-Gallon unit replaces the instant-on tankless design with a traditional 4.0-gallon tank. It offers dual gas and electric power sources, providing a reliable backup if propane runs out. This model is heavier at 32.9 pounds and measures 12.7 inches on each side. You get steady recovery rates rather than unlimited hot water flow. It suits RVers who prioritize consistent temperature stability and backup heating options over the compact, lightweight nature of tankless systems. The steel construction is built for durability in standard RV bays.
Ranein 65,000 BTU RV Tankless Water Heater
The Ranein 65,000 BTU heater delivers a higher flow rate of 3.9 GPM compared to the Furrion’s 2.4 GPM. It is significantly lighter at 15.5 pounds and features a compact 15-inch cubic design. This unit includes detailed remote monitoring capabilities, allowing you to track performance closely. It is best for full-time RVers or cold-weather travelers who need strong, simultaneous hot water for multiple uses. You gain higher output and freeze protection but sacrifice the specific vibration resistance and Suburban door compatibility that the Furrion provides for easy retrofits.
APUS 68,000 BTU RV Propane Water Heater
The APUS 68,000 BTU model offers a robust 3.9 GPM flow rate, outperforming the Furrion’s 2.4 GPM output. It weighs only 24 pounds and measures 14.2 inches wide and deep. This unit includes a remote control for convenient temperature adjustment. It is designed for high-altitude camping, ensuring consistent performance where other heaters might struggle. You get strong heating power and altitude adaptability. However, you give up the VibrationSmart technology and the specific 16.14-inch door fitment that makes the Furrion ideal for replacing older Suburban tank units.
VEVOR 42,000 BTU Propane RV Tankless Water Heater
The VEVOR 42,000 BTU heater provides a propane-powered solution with remote control convenience. It weighs 26.9 pounds and fits a 15-inch cubic space. This unit prioritizes heating speed and is suitable for rigs where propane is the primary fuel source. It offers a straightforward installation for outdoor utility connections. You gain reliable heating performance and easy remote operation. You do not get the higher flow rate of the 65K BTU models or the specialized vibration damping of the Furrion. It is a solid choice for general RV shower needs without complex installation requirements.
Camplux 5L Portable Propane Water Heater
The Camplux 5L is a portable, battery-operated heater designed for camping and off-grid showers. It has a low flow rate of 1.32 GPM, much lower than the Furrion’s 2.4 GPM. It is extremely lightweight at 10 pounds and compact, measuring 11.4 inches wide. This unit is ideal for low-pressure compatibility and portability. You gain the ability to shower anywhere with propane, but you sacrifice in-RV installation and high flow rates. It is best for campers who prioritize mobility and low power consumption over the steady, high-volume hot water provided by permanent RV water heaters.
Orbek 60,000 BTU 12V RV Tankless Water Heater
The Orbek 60,000 BTU heater offers robust performance with integrated pressure regulation and altitude adaptability. It weighs 20.5 pounds and measures 12.7 inches on each side. This unit provides remote temperature control for precise adjustments. It is designed for standard RV cutouts, making installation straightforward. You get reliable propane heating with built-in safety features for high-altitude travel. You give up the specific Vortex temperature mixing technology and the vibration-resistant components of the Furrion. It is a practical choice for travelers who need altitude compensation and straightforward remote operation without extra bulk.
