APUS vs FOGATTI RV Heater Specs

Heating capacity

Edge: APUS 68,000 BTU RV Propane Water Heater

The APUS model delivers 68,000 BTU of heating power, while the FOGATTI unit provides 48,000 BTU. Higher BTU ratings generally support greater water flow rates. This means the APUS can handle more demanding hot water usage simultaneously. If you need higher output for larger showers or multiple fixtures, the APUS has a clear advantage. The FOGATTI output is sufficient for standard RV needs but is lower in raw power.

Water flow rate

Edge: APUS 68,000 BTU RV Propane Water Heater

Flow rate determines how much hot water you get per minute. The APUS offers 3.9 gallons per minute (GPM). The FOGATTI provides 2.5 GPM. A higher GPM allows for stronger shower pressure and faster filling of sinks. The APUS supports this higher volume with its increased BTU rating. You will notice a difference in flow strength between the two units. The APUS is better for high-volume demands.

Safety valve rating

Edge: APUS 68,000 BTU RV Propane Water Heater

Both heaters include built-in pressure relief valves for safety. The APUS features a 203 PSI valve. The FOGATTI includes a 150 PSI valve. A higher PSI rating indicates the system can handle greater internal water pressure before releasing it. This is important for RV plumbing systems that may experience pressure spikes. The APUS valve offers a higher safety margin for pressure management compared to the FOGATTI model.

Temperature range

Edge: Tie

You can adjust the output temperature on both units. The FOGATTI remote allows settings from 95°F to 123°F. The APUS maintains an outlet temperature between 95°F and 124°F. Both ranges cover typical showering and cleaning needs. The difference is minimal, with the APUS reaching one degree higher. For most users, this slight variation does not impact comfort or functionality. You can achieve similar warmth with either device.

Installation size

Edge: APUS 68,000 BTU RV Propane Water Heater

Physical dimensions affect how easily the unit fits your RV compartment. The FOGATTI measures 15 x 15 x 15 inches. The APUS is slightly smaller at 14.96 x 14.96 x 14.18 inches. Both are designed to replace standard tank heaters. The APUS has a specific cutout requirement of 12.6 x 12.6 inches. The FOGATTI lists door options for various sizes. The APUS is marginally more compact in all dimensions.

Does APUS work well at high altitudes?

Yes, the APUS unit is specifically suited for high-altitude performance. It delivers 68,000 BTU of heating power, which helps maintain consistent water temperatures when air density is lower. This makes it a reliable option for travelers who frequently drive through mountainous regions or camp at elevated elevations where standard heaters might struggle to ignite or heat water efficiently.

Can I control the APUS heater from inside?

Yes, the APUS model includes remote control capabilities. You can adjust settings from inside the cabin without needing to access the exterior compartment. This feature adds convenience for RV owners who want to monitor or change water temperature settings comfortably.
