摘要

Improvements in the manufacture of heating boilers by elements, characterized by comprising the arrangement on the external faces of each of the components of the boiler, multiple projections of full structure and rounded outer surfaces uniformly arranged on the surface of said elements and in the same spatial arrangement for all the elements of the boiler, so that once assembled are facing each other with very small separation, determining deflectors for the passage of gases, with an increase in the radiation surface, constituting in addition the surfaces internal of said elements with smooth structure in order to avoid areas of low water velocity.
