FOGATTI vs Westinghouse Spec Comparison
fuel type
The FOGATTI InstaShower 8 Plus runs on propane, making it ideal for off-grid RV travel where electrical hookups are unavailable. It uses staged combustion technology to manage flame intensity at high altitudes. In contrast, the Westinghouse 24kW is a fully electric unit requiring a 240V power source. This electric design suits permanent residential installations with reliable grid access. Your choice depends on your power availability. Propane offers mobility for camping, while electricity provides consistent performance for fixed home plumbing systems without the need to manage fuel tanks.
flow rate
Flow rate determines how much hot water you get per minute. The Westinghouse 24kW delivers up to 5.55 GPM, which is sufficient for running a shower and a sink simultaneously in a whole-house setting. The FOGATTI InstaShower 8 Plus provides a maximum of 2.9 GPM. This lower output is adequate for single-user RV showers but may struggle with multiple fixtures. If you need high volume for a family home, the Westinghouse has a clear advantage. For a single RV bathroom tap, the FOGATTI output is sufficient.
voltage
Electrical requirements differ significantly between these two units. The Westinghouse 24kW heater operates on 240V and requires a substantial 100A electrical service, utilizing three 40-amp breakers and 8 AWG wire. This demands professional installation in a home with adequate panel capacity. The FOGATTI InstaShower 8 Plus uses 12V DC power, which is standard for recreational vehicles. It draws power directly from your RV battery system. This low-voltage setup allows for easy integration into mobile living spaces without complex electrical upgrades.
installation location
These heaters are designed for distinct environments. The FOGATTI InstaShower 8 Plus is built for RVs, featuring a compact 15x15x15 inch cube shape that replaces standard 6-gallon tank heaters. It includes a 15x15 inch door for easy replacement of existing Suburban or Atwood units. The Westinghouse 24kW is a whole-house unit measuring 17.1 inches high, 13 inches wide, and 4.3 inches deep. Its slim profile mounts flush against a wall, saving space in apartments or homes. One is for mobile travel, the other for stationary residential use.
smart features
The Westinghouse 24kW includes built-in Wi-Fi connectivity, allowing you to adjust temperature and monitor usage via a smartphone app or voice commands through Alexa and Google Home. This smart integration adds convenience for modern homes. The FOGATTI InstaShower 8 Plus does not list Wi-Fi capabilities. Instead, it comes with a 2-meter intelligent remote controller for manual temperature adjustment. If you prefer digital control and remote monitoring, the Westinghouse offers superior technology. If you prefer simple physical remote control, the FOGATTI option is straightforward.
safety certifications
Safety standards are critical for gas and electric heaters. The FOGATTI InstaShower 8 Plus is CSA certified, ensuring it meets specific safety standards for propane appliances. It includes a built-in pressure relief valve, forced exhaust fan, and automatic gas shut-off for flame failure. The Westinghouse 24kW data does not explicitly list third-party safety certifications like CSA or UL in the provided specifications. Both units have inherent safety features, but the FOGATTI provides documented certification details for peace of mind regarding gas combustion safety.
Which Tankless Heater Fits Your Needs
RV travelers needing propane power
The FOGATTI unit runs on propane, so you do not need electrical hookups. Its 55,000 BTU output delivers up to 2.9 GPM for steady showers. It also operates reliably at high altitudes up to 9,800 feet. The compact 15-inch cube design replaces standard RV tank heaters easily. This makes it ideal for off-grid camping trips where gas is available.
Homeowners wanting whole house hot water
The Westinghouse heater provides 5.55 GPM, which supports simultaneous use in bathrooms and kitchens. Its 24kW electric power suits residential 240V circuits. The slim 4.3-inch depth mounts flush against walls to save space. It includes WiFi control for remote temperature adjustments. This unit delivers continuous hot water for entire households without running out.
Users preferring smart home integration
You can adjust temperature settings and monitor usage via an app or voice commands with Alexa and Google Home. The Westinghouse model features built-in WiFi connectivity for modern smart home setups. This allows you to manage hot water remotely without touching the unit. The FOGATTI model lacks these digital controls and relies on a physical remote.
