Pour réchauffer l’eau refroidie du réseau, on a monté une chambre à eau (6) dans le passage de gaz de la chaudière (1). Pour accumuler l’eau réchauffée du réseau pendant la période entre deux saisons de chauffage, le circuit d’eau directe du réseau a été doté d’un plan d’eau isolé (19). L’invention permet d’augmenter le degré d’utilisation du combustible pour réchauffer le caloporteur au moyen d’une technique intégrée qui comprend la réutilisation de la chaleur des gaz émis, d’augmenter la quantité de chaleur transportée jusqu’au consommateur et de garder le caloporteur à basse température, ainsi que d’accumuler et de garder le caloporteur à haute température dans la période entre deux saisons de chauffage et d’atténuer ainsi le caractère cyclique de la consommation de celui-ci.
