- This condenser 38 includes a primary 39 and a secondary 40 connected to the network 3.
- the thermal conduction breaking means 37 can here be very simple such as a short section of piping made of non-conductive material heat, because in this operating mode, water does not circulate in the condenser 38.

- This water, coming as in heating mode, from the outlet of the radiator 4 is directed by the three-way valve 35 closed on track 33 and open on track 34, to condenser 38.
- the water leaving the air conditioner 5b borrows the pipe 36 towards the outside cooler 6, through the three-way valve 7, the way 8 of which is closed and track 9 is open, pump 2 being in service.
- the cooling of the ambient air on passing over the evaporator 41 causes the condensation and the water thus collected by a collector 45 must be evacuated. This can be done in a conventional gravity fashion, by flow in small flexible or rigid pipes easy to install in plinth. These waters of condensation can be evacuated by their introduction under pressure into the heating network 3 via a pump 46 and a non-return valve 47.
- a "by-pass" system can be implemented to avoid the consequences due to the arrival of pressurized hot water to the condensers 38 of the air conditioners 5a.
