FST semi-fast DHW heater

The FST DHW heaters are pre-assembled units which, in combination with a storage tank of a suitable size, allow you to quickly produce and store large quantities of domestic hot water at a pre-set temperature.

All in a compact space thanks to the ultra-compact monobloc structure and the space-saving dimensions of the control unit.

Through the user-friendly, intuitive electronic control panel, it is possible to control the device by setting a variety of factors, such as the temperature setpoint, pump operation and the programming of the anti-legionella treatments.

Available in 150 standard combinations, the FST can cover a wide range of requirements in terms of power (from 55 to 700kw). They are also designed to be used in a modular format which allows you to increase the power, for example, by adding exchanger plates.
