Answer: the one-pipe network, the two-pipe network and the octopus network.

With regard to central heating, hot water radiators can be linked together by three types of piping networks. First of all, the monotube network, which forms a single water circuit passing successively through all the radiators in the accommodation before returning to the boiler. The drawback of this network is that the water gradually loses its heat, the last piece being the worst-off. Then there is the most widespread two-pipe network. It is made up of two circuits, one supplying the radiators with hot water, the other recovering lukewarm water at the outlet of each radiator. Finally, there is a new type of network: the octopus network, in which each radiator has its own water supply and recovery circuit. The radiators are not connected to each other but directly to the boiler. You too, send us your brico question
