Abstract: Method and machine for preparing beverages, in particular infusions, such as coffee or tea, having a liquid supply source supplying a liquid, in particular water, an infusion chamber and an infusion circuit, which connects said supply source to said infusion chamber; the machine having an infusion circuit with a heat exchanger and a dispensing assembly, which is configured to heat the liquid at a predetermined temperature that is lower than the boiling temperature of the liquid, for example at approximately 90°, before the infusion of the liquid itself on the inside of the infusion chamber.

Abstract: Method, machine and boiler for the preparation of beverages, in particular infusions such as coffee or tea; wherein the boiler has a central tank which delimits a superheating area for a liquid and an outer tank positioned around the central tank so as to delimit a heating area for the liquid and to allow the heating of the liquid in the heating area by means of the heat generated in the superheating area; the heating area having a first outlet for supplying hot liquid, the superheating area having a second outlet for the supply of steam.
