CA 2123356
A gas-fired hot water heater having improved energy efficiency includes a plurality of second tubes, a plurality of first tubes which enclose the second tubes, and a cylindrical wall which encloses the first tubes. A number of fins are provided on the outer circumference of the second tubes. Cold water entering a first manifold passes downwardly in parallel fashion through the second tubes as hot gases of combustion emitted from a burner flow upwardly through the first tubes and the fins, thereby creating a highly efficient heat transfer from the hot gases to the water. An annular space between the cylindrical wall and an outer casing provides a thermal barrier to heat loss.
Un chauffe-eau au gaz permettant d'utiliser plus efficacement l'énergie comprend plusieurs seconds tubes, plusieurs premiers tubes qui contiennent les seconds tubes et une paroi cylindrique contenant les premiers tubes. Un certain nombre de bourrelets sont fournis à la circonférence extérieure des seconds tubes. L'eau froide qui entre dans un premier collecteur circule vers le bas et parallèlement dans les seconds tubes pendant que les gaz chauds émis par un brûleur circulent vers le haut dans les premiers tubes et les bourrelets, créant ainsi vers l'eau un transfert très efficace de la chaleur des gaz chauds. Un espace annulaire entre la paroi cylindrique et l'enveloppe extérieure forme un barrière thermique, empêchant la perte de chaleur.
