1. A machine for preparing beverages and other foods using hot water, with a hydraulic circuit including:
a water tank for storing water; a boiler to heat the water; a pump to feed the water to the boiler; a brewing unit that receives water from said boiler and into which a product for preparing the beverage or other food product is inserted; a magnetic field generator for treating the water to reduce the formation of limescale deposits in said hydraulic circuit; and a preheating device for preheating the water upstream of said boiler, wherein said preheating device is associated with said magnetic field generator and is arranged so that the water that passes through said magnetic field is at a temperature above the ambient temperature heated by said preheating device for treatment by the magnetic field generator and further heating by the boiler, and wherein said preheating device is arranged and designed to heat the water while it flows through the magnetic field.
