FAST EVO X 
The new open-flue instantaneous gas water heater with low NOx emissions. Both models feature ionized ignition and can be powered by batteries or cables. The attractive design is further enhanced by the LCD display (model C).
The entire range complies with the ErP 2018 regulation, which requires a reduction in NOx emissions. In addition to its high efficiency, the X range stands out for its ease of installation, compact size, and comfort.
FAST EVO X combines maximum installation simplicity with high user comfort. In fact, thanks to its technology, it guarantees operation even at minimal flow rates and hydraulic pressures.
To ensure maximum energy savings, we recommend pairing it with a natural or forced circulation solar system using the Solar Kit with Thermostatic Valve and Bypass. This way, if the water from the solar system is hot enough, it flows directly to the user without turning on the water heater.
Characteristics:
Low NOx: compliant with ErP 09/26/2018
Electronic flame detection
Continuous flame modulation thanks to the NTC probe placed at the exchanger outlet
Minimum operating pressure 0.1 bar
Operation even with minimal water flow rates of up to 2 l/min
Presence of water flow switch for accurate temperature control
Internal installation
