Title (EN) WATER HEATER
(FR) CHAUFFE-EAU
Abstract:
(EN) A water heater system includes a primary heat exchanger including a tank and at least one flue, and a secondary heat exchanger including a core and a flue gas flow path. The water heater is operable in a heating mode in which a combustor produces hot flue gas and a water pump flows water through the core of the secondary heat exchanger and into the tank, and in a non-heating mode in which the combustor and the water pump are inoperative. The flue gas flows from the combustor through the at least one flue to heat the water in the tank and then through the flue gas flow path to heat water in the core before being exhausted.
(FR) Cette invention concerne un système de chauffe-eau, comprenant un échangeur de chaleur primaire comprenant un réservoir et au moins un carneau, et un échangeur de chaleur secondaire comprenant un faisceau et un trajet d'écoulement de gaz de combustion. Le chauffe-eau peut fonctionner selon un mode de chauffage dans lequel une chambre de combustion produit un gaz de combustion chaud et une pompe à eau fait circuler de l'eau à travers le faisceau de l'échangeur de chaleur secondaire et dans le réservoir, et selon un mode de non-chauffage dans lequel la chambre de combustion et la pompe à eau sont inopérantes. Le gaz de combustion s'écoule depuis la chambre de combustion à travers le(s) carneau(x) pour chauffer l'eau dans le réservoir, puis à travers le trajet d'écoulement de gaz de combustion pour chauffer l'eau dans le faisceau avant d'être évacué.
