The invention relates to a forced draft household gas boiler having a sealed enclosure for the combustion assembly of the boiler. A sealed shell (15) envelopes a cylindrical heat exchanger (6) and is suspended in the upper half of a frame (1) from a horizontal plate (4) so that a central inlet opening (11) of the heat exchanger is in the axis of an outlet tube (32) of a fan (29) which directs an air/gas mixture into the burner. An outlet opening (23) for the combustion products collected in the sealed shell (15) is located within the circumference of the shell and at least approximately in the axis of an evacuation pipe (18) for evacuating combustion products external of the boiler.

Sealed forced-draft gas boiler disposition

A gas-tight chamber for a heat exchanger has a shell (12) forming the gas-tight chamber made of a light flexible or semirigid material such as rubber or thin silicone-treated sheet material which, because of its low weight and relative flexibility, absorbs all the vibrations produced and maintained by the burners, which eliminates the noise. The exchangers have a layer of longitudinal water tubes arranged concentrically around a central burner.
