Frequently asked questions

Which alternative offers the highest BTU output?

The APUS unit provides 68,000 BTU, making it the most powerful option on this list. This output exceeds the Forimo’s 61,000 BTU and the 60,000 BTU models from Orbek, HudeX, and RVPart Pro. Higher BTU generally supports faster heating, which suits high-flow shower needs.

Are there portable options for camping?

Yes, the Camplux F10 and GASLAND BS264 are designed for portable outdoor use. Both units deliver 2.64 GPM and are CSA-certified or feature overheat protection. They are lighter and more compact than the fixed RV models, weighing 15 and 22 pounds respectively, making them ideal for tight spaces.

Which models run on 12V DC power?

The Forimo and Orbek heaters are specified as 12V DC models. The RVPart Pro is also listed as a 12V DC solution. These units draw power from your RV’s standard 12-volt system, which is convenient for off-grid camping where shore power is unavailable. Other models do not specify this power requirement.

What is the smallest footprint available?

The Camplux F10 has the narrowest width at 5.9 inches. Its compact 5.9 by 5.9 by 18.5-inch dimensions make it significantly smaller than the bulky RV units. The Orbek is the most compact fixed-mount option, measuring 12.7 inches on each side, offering a balance of size and capacity.

Do any units include a remote control?

The APUS model features a remote control for temperature adjustment. This allows you to change settings without reaching the unit. The RVPart Pro uses digital control on the device itself rather than a remote. Other listed models do not mention remote operation capabilities in their specifications.

Which heater is best for high-altitude travel?

The Orbek is specifically noted for high-altitude performance. The HudeX model is also described as suitable for high-altitude replacement of standard tanks. These units are designed to maintain reliable hot water delivery even when atmospheric pressure drops, which is common during mountain travel or in elevated camping locations.

Which model is the lightest?

The Camplux F10 weighs 15 pounds, making it the lightest option. The GASLAND unit is heavier at 22 pounds. The fixed RV models range from 20.5 to 24 pounds. If you need to move the heater frequently, the portable Camplux is the easiest to carry and store.
