Abstract
A gas burner associated with a combustion chamber constitutes a fluid-tight removable heating unit immersible in a liquid to be heated. The unit has a caisson including a chamber for premixing and distributing gaseous fuel and a combustion chamber separated from the premixing chamber by a flame stabilizing grate. The caisson has traversed, in fluid-tight relationship thereto, by ducts permitting thermosiphon circulation of the surrounding liquid and increasing the exchange surfaces constituted by the walls of the caisson.
