InstaShower 9 Pro vs 8 Pro Specs
Heating power and flow
The FOGATTI InstaShower 9 Pro delivers 66,000 BTUs of heating power, producing up to 3.6 gallons per minute of hot water. This higher output allows you to run multiple fixtures simultaneously in your RV without significant temperature drops. In contrast, the InstaShower 8 Pro provides 60,000 BTUs and a maximum flow of 2.9 GPM. While still sufficient for most single-shower scenarios, the 9 Pro offers a stronger stream and greater capacity for larger travel trailers or family use. The 9 Pro clearly wins for those needing maximum hot water volume.
Voltage requirements
The InstaShower 8 Pro is explicitly listed as running on 12V DC power, which is standard for most RV electrical systems. This makes it directly compatible with your vehicle’s battery and inverter setup without needing additional power conversion. The data for the InstaShower 9 Pro does not specify its voltage requirements. While it likely uses similar low-voltage controls, the lack of explicit confirmation in the provided specifications means you cannot be certain it matches the 8 Pro’s electrical profile. This uncertainty gives the 8 Pro a slight edge for verified compatibility.
Temperature precision
Both units feature precise temperature control, but the InstaShower 9 Pro specifies an accuracy of ±1°F. This tight tolerance ensures the water temperature remains stable, preventing sudden hot or cold shocks during your shower. The InstaShower 8 Pro mentions flame intensity control to prevent overheating but does not list a specific temperature deviation range in its key specs. For users who prioritize exact temperature settings, the 9 Pro’s stated ±1°F precision offers a clear advantage in consistency and comfort.
Remote control range
Both water heaters include an intelligent remote controller for convenient operation. The InstaShower 9 Pro allows you to control the unit from up to 6.6 feet away. The InstaShower 8 Pro specifies a range of up to 2 meters, which converts to approximately 6.56 feet. These ranges are virtually identical, providing similar convenience for adjusting settings from a distance. Since the difference is negligible, this aspect is considered a tie between the two models.
Altitude performance
Both the InstaShower 9 Pro and the InstaShower 8 Pro are designed to operate efficiently at high elevations. Each model is rated to work smoothly at altitudes up to 9,800 feet. The 9 Pro highlights its upgraded NIDEC fan with 300Pa of power to handle winds up to Beaufort scale 9. The 8 Pro mentions a high-altitude suitability mode that controls flame intensity. Since both achieve the same altitude rating and share similar high-altitude features, neither has a distinct advantage in this category.
