Title
(EN) WATER HEATING APPARATUS
(FR) APPAREIL DE CHAUFFAGE DE L'EAU
Abstract
(EN)
A water heating apparatus (10) includes a body (12) defining a water jacket chamber (14) around an open ended flue (62). An inlet (16) leads into the water jacket chamber and an outlet (18) leads from the water jacket chamber at a position spaced from the inlet (16). At least the outlet (18) is connected to the water jacket chamber (14) by a length of pipe (40), at least part of which is positioned inside the flue (62). A burner (48) is positioned in register with a lower end of the flue (62) to heat water in the chamber (14). The body (12) is in two parts (20,22) and incorporates a pressure relief valve (54).
(FR)
L'invention concerne un appareil (10) de chauffage de l'eau comprenant un corps (12) qui définit un compartiment (14) de chemise d'eau entourant un tube de fumée (62) à extrémité ouverte. Un orifice d'admission (16) conduit au compartiment de chemise d'eau et un orifice d'évacuation (18) conduit du compartiment de chemise d'eau à une position espacée de l'orifice d'admission (16). Au moins l'orifice d'évacuation (18) est relié au compartiment (14) de chemise d'eau par une longueur de tuyau (40) dont au moins une partie est disposée à l'intérieur du tube de fumée (62). Un brûleur (48) est aligné avec une extrémité inférieure du tube de fumée (62) pour chauffer l'eau dans le compartiment (14). Le corps (12) est en deux parties (20, 22) et comprend une soupape (54) de sécurité.
