Abstract (en)
[origin: EP0030183A1] 1. A heater body for a domestic hot water central heating boiler heated by gas of the forced draught type comprising a longitudinal bundle of tubes having an elongate section in which the water to be re-heated circulates, disposed along the generatrix of a cylinder for forming an internal cylindrical combustion chamber, characterized by the fact that the median longitudinal plane A1 B1 of each of the tubes (10) is inclined at an angle alpha relative to the radial direction AB of flow of the combustion gas for creating an oblique incidence of this gas on said tubes.
