The APUS 80,000 BTU model offers higher heating power than the RIWORY’s 65,000 BTU maximum. It features a more compact 14.2-inch square footprint, which may not fit 18x18 inch openings. Weighing 24.1 pounds, it is lighter than the RIWORY’s 36-pound unit. This model targets campers who prioritize high flow rates and high-altitude performance over aesthetic matching. It includes a wired remote for temperature control. You should choose this if your RV opening is smaller than 18x18 inches and you need extra power for mountain travel. It sacrifices the included door assembly found with the RIWORY.
FOGATTI InstaShower 7 RV Propane Tankless Water Heater
The FOGATTI InstaShower 7 uses a 15x15 inch form factor, making it unsuitable for 18x18 inch replacements without modification.

It is a solid choice for those who do not need the 18x18 inch door or the extensive safety package included with the RIWORY.
Suburban 6-Gallon Gas and Electric RV Water Heater
The Suburban 6-Gallon unit uses electric power instead of propane, requiring a different fuel source. It provides stored hot water rather than instant heating, which changes the usage pattern. The unit fits in a 12.7-inch square space, smaller than the RIWORY’s 18x18 inch opening. It weighs 32.9 pounds, slightly less than the RIWORY. This model is best for RVers who camp with electric hookups and need a consistent supply of hot water. It sacrifices instant heating speed for tank reliability.
