Title (EN) GAS BOILER HAVING CLOSED-TYPE CISTERN TANK
(FR) CHAUDIÈRE À GAZ À CITERNE FERMÉE
Abstract: front page image
(EN)Provided is a gas boiler having a closed-type cistern tank with no diaphragm, in which the volume of the cistern tank can be reduced, the closed type cistern tank storing returned heating water and absorbing a pressure change of the heating water. The cistern tank having no diaphragm is constructed in a closed type such that an internal space thereof is isolated from the atmosphere, and includes a heating water inlet through which the heating water is introduced, a heating water outlet through which the heating water is discharged toward a circulation pump, a water level detecting sensor which detects the water level of the heating water stored in the cistern tank, and a safety valve for maintaining the pressure of an internal space of the cistern tank to less than a predetermined value.
(FR)Chaudière à gaz à citerne du type fermé sans membrane, dans laquelle le volume de la citerne peut être réduit, la citerne fermée stockant l'eau de chauffage de retour et absorbant le changement de pression de l'eau de chauffage. La citerne sans membrane est du type fermé de sorte que son espace interne est isolé de l'atmosphère, et comprend une admission d'eau de chauffage par laquelle est introduite l'eau de chauffage, et une sortie d'eau de chauffage par laquelle l'eau de chauffage est déchargée vers une pompe de circulation. Une sonde de niveau d'eau détecte le niveau de l'eau de chauffage stockée dans la citerne et une soupape de sécurité maintient la pression de l'espace intérieur de la citerne en dessous d'une valeur prédéterminée.
