fitting T-junctions between
pipes, and real lengths of pipelines for each hydraulic circuit to determine the pipe
diameter and pressure loss.
The main components of the circuits are:

In this way we can identify the number of bends,

￿ separation cocks, which ensure the separation of the active elements to allow

local intervention to the device without affecting the other equipment;

recirculation pump;

￿

mixing valve, used to control the start temperature and to reduce the duration of
the transition mode;

￿

division valve, through which the work area in the hot water tank is chosen,
depending on the temperature of the water at the bottom of the tank;

￿

separation valve with the role of select hot or cold water to supply the coil
convectors.
