This drawing illustrates a hydronic central heating system designed for a multi-unit residential building. The analysis includes a close examination of the piping layout, system components, and the technical details provided on the plan.
The layout shows that each apartment is supplied by central vertical risers, which distribute heated water to the radiators and towel warmers in each unit. The distribution network is made up of PEX piping (cross-linked polyethylene), shown in orange on the plan, which carries both supply and return lines to and from each heating element.
The main heat emitters throughout the building are wall-mounted radiators, with heated towel rails installed in the bathrooms to provide additional comfort. Each heating fixture is labeled with a data tag containing key technical information used for selecting equipment, ensuring system balance, and verifying performance.
A closer look at a typical data tag reveals several important specifications:
-
Chauffage Central – Radiateur identifies the fixture as a central heating radiator.
-
Puissance: 2500W indicates the radiator’s required heat output to maintain the target room temperature.
-
Débit: 107 Kg/h refers to the mass flow rate of hot water needed per hour to deliver the specified heat output.
-
Alimentation shows the radiator’s connection point within the system.
