As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
The HUDEX 60,000 BTU RV propane heater delivers steady hot water at elevations up to 10,827 feet with intelligent freeze protection. If you need hudex RV tankless water heater alternatives, you might want a different flow rate, size, or feature set. This unit fits standard 15x15-inch openings and offers CSA safety certifications, but its 3.7 GPM flow may not suit everyone. Some travelers prioritize higher flow for multiple showers, while others need a more compact design for smaller RVs. You might also prefer remote control access or a different color option.
The 6 picks in this list were chosen because their specifications overlap with the original product. Each alternative shares key traits like propane fuel type and RV use, but varies in BTU output, physical dimensions, or additional features. For instance, some models offer higher BTU ratings for faster heating, while others provide remote controls for easier temperature adjustment. Others are designed for outdoor use or solo camping with lower flow rates. This comparison helps you find a unit that matches your specific needs, whether you require high-altitude stability, a compact footprint, or enhanced safety features. Review the specs to see which option fits your RV best.
How HUDEX Alternatives Compare
APUS 68,000 BTU RV Propane Water Heater
The APUS model offers 68,000 BTU, which is 8,000 BTU more than the HUDEX unit. This higher output supports a stronger flow rate, making it better for full RV showers where you need speed. It also includes remote control functionality, a feature not listed for the HUDEX. The APUS is slightly narrower at 14.2 inches wide compared to the HUDEX 16-inch width. You should choose this if you prioritize maximum hot water volume and convenient remote adjustments over the HUDEX’s specific freeze-protection range.
VEVOR 42,000 BTU Propane RV Tankless Water Heater
The VEVOR heater provides 42,000 BTU, which is 18,000 BTU less than the HUDEX 60,000 BTU model. This lower output means a reduced flow rate, so it is less suitable for high-demand showers. However, it shares the standard 15x15-inch footprint, making it a direct drop-in replacement for many RV compartments. It includes remote control and is rated for outdoor utility use. Pick this unit if you need a sturdy door-replacement option and do not require the higher heating power of the HUDEX for larger households.
Camplux 5L Portable Propane Water Heater
The Camplux 5L is a portable unit weighing only 10 pounds, significantly lighter than the HUDEX. It is designed for outdoor camping rather than permanent RV installation. It lacks the high flow rate and elevation stability of the HUDEX, which operates up to 10,827 feet. This model suits solo campers or small groups using gravity-fed water sources. Choose this if you need a lightweight, battery-operated solution for off-grid showers rather than a fixed replacement for your RV’s standard water heater compartment.
Orbek 60,000 BTU 12V RV Tankless Water Heater
The Orbek unit matches the HUDEX at 60,000 BTU but has a more compact square footprint of 12.7 inches on each side. This makes it suitable for smaller openings where the HUDEX 16-inch width would not fit. It includes a built-in pressure relief valve and maintains high-altitude performance similar to the HUDEX. However, it offers a lower flow rate, making it better for solo travelers or couples. Select this if you need a straightforward propane replacement for a standard 15x15 or 18x18 opening with a smaller physical profile.
Camplux 1.58 GPM Portable Propane Water Heater
The Camplux BW158G provides a flow rate of 1.58 GPM, which is much lower than the HUDEX 3.7 GPM. It is a compact, portable unit weighing 13 pounds, designed for camping rather than RV installation. It lacks the high BTU output and elevation stability of the HUDEX. This model is ideal for lightweight camping, pet washing, or low-pressure setups. You should pick this only if you prioritize portability and do not need continuous hot water for full RV showers or dishwashing.
FOGATTI InstaShower 8 Plus RV Tankless Water Heater
The FOGATTI InstaShower 8 Plus shares the standard 15x15-inch footprint of the HUDEX, making it a compatible replacement for many RV compartments. It provides continuous hot water and is ready for high-altitude camping. While it offers similar elevation stability, it does not list intelligent freeze protection or the same temperature control range as the HUDEX. It includes accessories for installation. Choose this unit if you want a reliable tank replacement with included hardware and do not require the specific staged-combustion technology found in the HUDEX model.
