Comparing Key Specs and Use Cases
Rheem IKONIC 11.2 GPM Propane Tankless Water Heater
The Rheem IKONIC offers 11.2 GPM with recirculation, significantly higher than the Bosch 830 ES LP’s 8.3 GPM. This extra flow suits larger households with multiple simultaneous demands. It shares the propane fuel type and indoor installation profile. However, it weighs 86 pounds and measures 28.6 inches tall, slightly larger than the Bosch unit. The Rheem adds WiFi connectivity for remote monitoring, a feature absent in the Bosch. If you need higher capacity and smart tracking, the Rheem is the stronger choice. If you prefer a simpler setup without digital integration, the Bosch remains a solid, efficient option for standard indoor propane needs.
APUS 68,000 BTU RV Propane Water Heater
The APUS 68,000 BTU unit targets RVs rather than whole-home use. Its 68,000 BTU input is far lower than the Bosch’s 175,000 BTU, reflecting its smaller scale. It weighs only 24 pounds and fits in a compact 15-inch cube, making it easy to install in tight RV spaces. Unlike the Bosch, it is designed to replace standard 6-12 gallon RV tanks. It lacks the high flow rate needed for multiple indoor showers. If you travel frequently and need a lightweight, direct replacement for an RV tank, this model fits. For a stationary home requiring high-volume hot water, the Bosch is the appropriate choice.
VEVOR 42,000 BTU Propane RV Tankless Water Heater

It weighs 26.9 pounds and measures 15 inches square, offering a compact footprint. This unit suits travelers who value convenience and portability more than high capacity. It does not match the Bosch’s 8.3 GPM output or its suitability for indoor residential installation. If you need a budget-friendly, remote-controlled option for an RV, the VEVOR works well. For a home requiring consistent, high-volume hot water, the Bosch provides the necessary power and capacity.
Camplux 5L Portable Propane Water Heater
The Camplux 5L is a portable outdoor unit designed for camping and solo showers. It weighs just 10 pounds and measures 4.33 inches in height, making it highly portable compared to the Bosch’s 80-pound indoor unit. It lacks the high flow rate and BTU input needed for whole-home use. Its overheat protection adds safety for outdoor scenarios. It is not suitable for indoor installation or high-demand households. If you need lightweight, safe hot water for camping or dishwashing on the go, this model is ideal. For a permanent indoor solution with high capacity, the Bosch is the correct choice.
Orbek 60,000 BTU 12V RV Tankless Water Heater
The Orbek 60,000 BTU unit is designed for RV owners needing a standard cutout replacement. It weighs 20.5 pounds and fits in a 12.7-inch cube, much smaller than the Bosch.
