Propane RV Heater Comparison
Heating power output
The FOGATTI InstaShower 8 Pro RV delivers 60,000 BTUs of heating power, while the InstaShower 8 Plus RV provides 55,000 BTUs. Both units produce the same maximum flow rate of 2.9 gallons per minute. The higher BTU rating on the Pro model suggests it can heat water more aggressively or recover temperature faster during high-demand usage. For most RV showers, the 2.9 GPM limit is the practical ceiling regardless of the burner size. However, if you frequently use multiple fixtures or need rapid recovery in cold conditions, the extra 5,000 BTUs on the Pro model offers a clear technical advantage. This difference matters most when inlet water temperatures drop significantly.
Water filtration
The InstaShower 8 Pro RV includes a built-in filter screen designed to catch large particles like dust and sand from the incoming water supply. The InstaShower 8 Plus RV data does not mention this specific internal filtration component. RV water systems often contain debris that can clog small orifices or damage internal valves. Having a pre-filter integrated into the unit protects the combustion system and maintains consistent performance over time. If your campground water quality is inconsistent, the Pro model offers better protection for its internal components without requiring you to install an external filter separately.
Included accessories
Both units come with a pressure relief valve and an intelligent remote controller that works up to 2 meters away. The InstaShower 8 Pro RV also includes a decorative frame measuring 17.64 by 17.64 inches to cover the installation opening. The InstaShower 8 Plus RV data lists a 15 by 15 inch door but does not specify a decorative frame. The decorative frame helps hide gaps between the heater and your RV wall for a cleaner look. This is a minor aesthetic and installation detail, but it adds value if you want a finished appearance without buying extra trim pieces.
High altitude performance
Both the InstaShower 8 Plus RV and the InstaShower 8 Pro RV are rated for high-altitude operation up to 9,800 feet. They both use staged combustion technology to adjust flame intensity in thinner air. This ensures stable heating and prevents overheating when you travel to higher elevations like the Denver plateau. Since both models share this exact specification and technology, there is no performance difference in this area. You can trust either unit to function safely and efficiently regardless of your elevation. This is a shared strength for RV travelers who cross mountain ranges.
Physical dimensions
Both water heaters are identical in size, measuring 15 by 15 by 15 inches. They are designed to replace 6-gallon tank water heaters from brands like Suburban and Atwood. The installation opening is 13 by 13 inches, and the door is 15 by 15 inches. This standard footprint means the physical installation process is the same for both models. You do not need to modify your RV structure or cut new holes for either unit. The compact cube shape fits neatly into standard RV utility closets.
Which Fogatti Model Fits Your Needs
RVers needing higher heating power
The InstaShower 8 Pro RV delivers 60,000 BTUs, offering more heating power than the Plus model's 55,000 BTUs. Both units maintain a 2.9 GPM flow rate and operate on 12V DC propane. The Pro's extra BTU capacity helps maintain consistent water temperatures during colder conditions or higher demand scenarios in your travel trailer.
Users wanting included remote control
The InstaShower 8 Plus RV comes with an intelligent remote controller that works up to 2 meters away. This feature allows you to adjust settings from a distance without leaving the shower. The Plus model includes this convenience item directly in the package, ensuring you have immediate control over your hot water temperature.
Travelers prioritizing water filtration
The InstaShower 8 Pro RV includes a built-in filter screen designed to catch large particles like dust and sand. This protection helps keep the internal components clean during RV travel. If you frequently camp in dusty environments, this added filtration layer offers an extra layer of reliability for your tankless water heating system.
