The brewing unit according to claim 9, wherein said first brewing chamber portion and said second brewing chamber portion are moved by a single control lever. 11. The brewing unit according to claim 9, comprising guiding channels for insertion of a capsule in a brewing position, and retention members to retain said capsule in said brewing position before and during closing of said brewing chamber. 12. The brewing unit according to claim 11, wherein said retention members are configured to disengage said capsule when said first and said second brewing chamber portions are moved apart to open the brewing chamber after completion of a brewing cycle. 13. The brewing unit according to 10, comprising guiding channels for insertion of a capsule in a brewing position, and retention members to retain said capsule in said brewing position before and during closing of said brewing chamber, wherein said single control lever controls cam profiles which act on said retention members to disengage said capsule from said retention members when the brewing chamber is opened by said single control lever. 14. The brewing unit according to claim 11, wherein said guiding channels are configured to receive the capsule by gravity. 15. The brewing unit according to claim 1, wherein said water heater is movable along with one of said first brewing chamber portion and said second brewing chamber portion during closing and opening of the brewing chamber. 16. The brewing unit according to claim 15, wherein said water heater and one of said first and brewing chamber portions movable with said water heater are housed in a slidable cover. 17. A beverage preparing machine including a brewing unit for a production of a beverage, the brewing unit comprising: a brewing chamber comprising first and second brewing chamber portions movable one with respect to the other;a flow through water heater having an electric resistor and a water heating duct;a hot water feeding duct for feeding hot water from said water heater via the water heating duct to said brewing chamber; anda beverage dispensing duct from which said beverage is dispensed from the brewing chamber to an outer beverage dispensing spout;wherein said water heater has a body made of heat-conductive material and wherein the body of the water heater surrounds a cavity through which said beverage dispensing duct extends for connection to the outer beverage dispensing spout, andwherein said body encloses the electric resistor and the water heating duct, wherein heat generated by the electric resistor, when powered, heats water flowing through the water heating duct by heat conduction through the heat-conductive material forming the body. 18. A brewing unit for a production of a beverage, comprising: a brewing chamber comprising at least two brewing chamber portions movable one with respect to the other;a heater having a water heating duct;a hot water feeding duct for providing hot water from said heater; anda beverage dispensing duct from which said beverage is dispensed from the brewing chamber to an outer beverage dispensing spout;wherein said heater has a body that surrounds a cavity through which said beverage dispensing duct extends for connection to the outer beverage dispensing spout.
