Definitions

  • the extractor fan 5 is placed on the roof while the air is drawn from the basement of the collective dwelling. In either case, the path of the air between the inlet 10 and the outlet 13 is similar for each water heater 2.
  • the architecture of the aeraulic network in reverse circuit with the air inlet opposite the fan allows each thermodynamic water heater to see a similar pressure drop; thus no water heater is disadvantaged by its positioning in the aeraulic network.
