  • the heat pump 54 - or alternatively a battery of heat pumps - is directly hydraulically connected to the inlet reservoir 30 of the first circuit 14.
  • the circulator 182 is started, allowing a hydraulic transfer from the inlet reservoir 50 of the second circuit 16 to the inlet reservoir 30 of the first circuit 14.
  • the hydraulic connection 72 between the outlet reservoirs 32 and 52 allows hydraulic balancing between the first 14 and second 16 circuits.
  • the electronic module 26 gives priority to the domestic hot water network. More specifically, if the inlet tank 50 of the second circuit is requested to supply the heat exchangers 22, 122, 122 following an alert from the probes 94 of the balloons 20, 120, 220, the hydraulic transfer from the second circuit 16 to the first circuit 14 is reduced or interrupted.
  • the heating needs of the second circuit 16 are concentrated on specific periods of the day, in particular following significant withdrawals of domestic hot water from the tank(s) 20, 120, 220 in the morning and/or the evening.
  • the heat pump(s) 54 of the second circuit 16 are able to supply heating energy for the benefit of the first circuit 14.
  • valve 84 between the first tapping 85 and the inlet reservoir 50 of the second circuit 16 is progressively opened; while simultaneously, the valve 83 between the first tapping 85 and the inlet tank 30 of the first circuit 14 is progressively closed.
  • the battery 48 of heat pumps 34 is directly hydraulically connected to the inlet tank 50 of the second circuit 16.
  • the circulator 180 is started, allowing a hydraulic transfer from the inlet tank 30 of the first circuit 14 to the inlet tank 50 of the second circuit 16.
  • this case may require an increase point of the setpoint temperature T1 of the tank 30.
  • the installation comprises an auxiliary heat generator 58
  • said generator is preferably requested by the electronic module 26 as a priority, before resorting to hydraulic transfers between the first and second circuits.
  • the power devoted to heating domestic hot water is around 20% of the total power of a thermal installation.
  • the invention described above allows this power associated with the domestic hot water to occasionally supplement the power dedicated to domestic heating, during the time slots in which the heating of the domestic water is not required.
  • the first battery 48 of heat pumps 34 with a total power lower by 10 to 20% than the power dedicated to domestic heating in a conventional installation.
  • the thermal installation according to the invention adopts flexible operation in the event of failure of one or the other of its heat pumps, by allowing occasional compensation between the first and second circuits.
  • the thermal installation according to the invention is particularly suitable for equipping collective housing buildings.
