A boiler with a boiler casing carrying a heat exchange medium and a double wall bulkhead in the casing receiving the heat exchange medium therefrom and defining a combustion chamber. A fuel burner is arranged at the inlet of the combustion chamber and produces gases. A double wall bulkhead having a baffle wall portion opposite the inlet and two arcuate lateral wall portions extending from the baffle wall portion towards the inlet also receives the heat exchange medium from the casing and is positioned in the combustion chamber to define a baffle chamber reflecting and reversing the combustion gases to combustion gas conduits laterally adjacent the lateral arcuately shaped bulkhead wall portions. The baffle chamber and the lateral combustion gas conduits have the same height, and an exhaust flue receives the combustion gases from the conduits at the outlet of the combustion chamber.
