1. Hydraulic unit (1, 1 '') comprising: - a thermostatic mixing valve (10) that keeps the water flow output to a predetermined temperature, wherein said predetermined temperature is selected from a normal operating temperature and temperature treatment of legionella, - a valve dynamic balancing (9) and a valve area (6, 8) whose combined action maintains the maximum flow rate of water flow to the valve outlet dynamic balancing (9) constant .2. Hydraulic unit (1, 1 ') according to claim 1, wherein the normal operating temperature is selected between 30 and 60 ° C.3. Hydraulic unit (1, 1 ') according to claim 1, wherein the treatment temperature of leqionella is at least 61 ° C.4. Hydraulic unit (1, 1 '') according to claim 1, characterized by further comprising: - a flow meter (2), - an energy meter (3); - at least one ball valve (4); - a check valve (5), - a filter (7); - a motorized valve (11), - a ball valve with a temperature sensor (12), - a thermostat (13) located in the premises of a user, - a flow switch (14), - a heat exchanger (15), - a trap (16), - an electrical box (17), - four outputs (18A, 18B, 18C, 18D), - three inputs (19A, L9b , 19C) .5. Hydraulic unit (1, 1 ') according to claim 4, characterized by further comprising: - a primary flow circuit (25), - a primary circuit return line (22), - a heating circuit leg (23) ; - a heating circuit return line (24), - a circuit domestic cold water, AFS (20); and, - a circuit of hot water, hot water (21); 6. Hydraulic unit (1, 1 ') according to claim 5, wherein the thermostatic mixing valve (10) mixing water previously heated by the heat exchanger (15) with sanitary cold water coming from the circuit sanitary cold water, to maintain water flow to the outlet of the thermostatic mixing valve (10) to the preset temperature.
