Abstract
This exchanger comprises a pair of primary tubular bundles () surrounding a fuel or gas burner (), and a secondary tubular bundle () on which condensation of the steam contained in the burned gases discharged from the primary bundles occurs, wherein the three bundles () are mounted parallel, side-by-side inside a gas-tight casing (), and communicate with one another, with means being provided in order to circulate the water to be heated, between the tubes forming the secondary bundle () and the tubes forming the primary bundles (); the casing () is subdivided at the level of the secondary bundle () by a partition (-) that extends both inside and outside said bundle (), with the arrangement being such that a only a circumferential section of the latter is capable of being contacted and traversed by the hot gases coming from one of the two primary bundles (), and its remaining section being capable of being contacted and traversed only by the hot gases coming from the other primary bundle (). Household or industrial heating installation with high efficiency and low bulk.
