MACS® module is an external unit that immediately produces
hot domestic water, using the heat energy stored in the Buffer
thanks to the stainless steel plate exchanger, granting safety
and comfort with the possibility to regulate outlet temperature.
MACS® module is equipped with a thermostatic mixer in the
primary circuit inlet avoiding the plate exchanger to overheat
reducing risk of formation of calcium deposist.
