T-FAST i20 is an instantaneous domestic hot water production module that uses the working principle of a stainless steel plate heat exchanger to meet a wide use if coupled with buffer tanks.
The setting of the domestic hot water temperature is made through the regulation of the thermostatic actuator of the primary circuit mixing valve.
The primary circuit pump is controlled by means of a pressure switch electrically connected.
Is available a DHW recirculation pump kit.
