1. A machine for the homogenization and thermal treatment of at least one chosen from a liquid and a semi-liquid food product, comprising: a tank for containing the food product, the tank including at least one lateral wall and a bottom wall together forming a main volume of the tank;an electric first heater, operating to heat and so thermally treat the food product;a heating plant with a thermodynamic cycle comprising a circuit including at least a first heat exchanger and an operating fluid for circulating in the circuit;a second heater comprising said first heat exchanger, operating to heat and so thermally treat the food product by operation of the operating fluid circulating in the circuit;the tank including a well, the well positioned on the bottom wall of the tank, the well directly open and contiguous to the main volume of the tank via an opening in the bottom wall to form with the main volume a continuous containment volume in which the food product can freely circulate between the main volume and the well for storing and working the food product;a pump for circulating the food product between the well and the main volume, the pump including an impeller rotatably positioned in the well and open to the main volume and a motor for rotating the impeller to circulate the food product between the well and the main volume;wherein the electric first heater and the second heater are positioned to transmit heat at the well. 2. The machine according to claim 1, wherein the electric first heater is positioned to transmit heat to the food product through the bottom wall of the tank. 3. The machine according to claim 1, wherein the second heater is positioned to transmit heat to the food product through the at least one lateral wall of the tank. 4. The machine according to claim 1, wherein the electric first heater and the second heater are positioned to transmit heat to the food product at the tank. 5. The machine according to claim 4, wherein the electric first heater and the second heater are positioned to transmit heat to the food product through at least one chosen from the at least one lateral wall and the bottom wall of the tank. 6. The machine according to claim 1, wherein the electric first heater and the second heater are positioned to transmit heat through at least one wall of the well. 7. The machine according to claim 1, wherein the heating plant with thermodynamic cycle comprises a heating plant with a heat pump, where the operating fluid of the thermodynamic cycle is cooled in the first heat exchanger. 8. The machine according to claim 1, wherein the heating plant with thermodynamic cycle comprises a heating plant with invertible cycle. 9. The machine according to claim 1, wherein the circuit includes a second heat exchanger, a throttle for the operating fluid, a compressor for the operating fluid, and a by-pass branch, which is connected to the compressor for allowing a circulation of the operating fluid in the compressor and in the first heat exchanger and, in contrast, excluding circulation of the operating fluid in the second heat exchanger and the throttle. 10. The machine according to claim 9, comprising a switching valve, which is activated for connecting the by-pass branch to the compressor and consequently for excluding the circulation of the operating fluid in the second heat exchanger and the throttle. 11. The machine according to claim 1, wherein the operating fluid includes carbon dioxide. 12. The machine according to claim 1, wherein the first heat exchanger of the second heater and the first heater are interleaved with one another around an outer surface of the well. 13. The machine according to claim 12, wherein a clearance is provided between the impeller and the well such that the rotating impeller causes fluid to flow in one direction between the main volume and the well through a central portion of the opening and in an opposite direction between the main volume and the well through an outer portion of the same opening. 14. The machine according to claim 13, wherein the opening is a sole connection between the well and the main volume. 15. The machine according to claim 12, wherein the opening is a sole connection between the well and the main volume. 16. The machine according to claim 1, wherein a clearance is provided between the impeller and the well such that the rotating impeller causes fluid to flow in one direction between the main volume and the well through a central portion of the opening and in an opposite direction between the main volume and the well through an outer portion of the same opening. 17. The machine according to claim 16, wherein the opening is a sole connection between the well and the main volume. 18. The machine according to claim 1, wherein the opening is a sole connection between the well and the main volume.
