BIG T_FASTie EVO3 is a floor-standing module for the instantaneous production of large amount of domestic hot water. he function of the module is to heat the domestic hot water through the plate heat exchanger using the energy coming from a buffer tank. The advantage of this module is the production of domestic hot water in large volume, with a low primary flow temperature of 48°C (DHW set at 45°C). This allows the use of several energy sources, such as solar installations, heat pumps, biomass, etc

The B version is suitable to produce DHW when the temperature of the water stored inside the buffer is lower than 58°C, for example when the energy source is a heat pump or a condensing boiler
