slotted摘要：The economir compris: a chamber (1) delimited by a thermally insulated external shell (2), a main central duct (4) which connects the boiler (9) to the chimney (11), peripheral ducts (3) traverd by the diverted hot gas (14) and delimited by housings (12) traverd in countercurrent by the water to be preheated and a preferably motorid intermediate valve (5) which makes it possible to divert the hot gas to said peripheral ducts (3) when their temperature reaches a prefixed value. The fundamental characteristic consists in the end valve (7) which clos the duct which goes to the chimney, impeding or limiting the outlet of heat when the burner is off.
