1.3.6.1. Boiler
The boiler (A) is constructed of steel. A heat exchanger
connected to the brewing unit is attached to the boiler.
Water for coffee brewing is taken directly from the heat
exchanger. During brewing, cold water is sent inside of
the exchanger by the pump.
Inside the heat exchanger, cold water and the pre-exi-
sting hot water are mixed, thus obtaining optimal water
temperature for coffee infusion. The water is heated into
the boiler by an electrical heating element immersed in
the water (B).
