ABSTRACT:
A boiler which is primarily designed for the central heating of apartments has two separable elements constituted by the boiler furnace and a heat exchanger. The heat exchanger of single-unit construction surmounts a completely open section of the boiler furnace and carries a gas or fuel-oil burner, the flame of which is directed away from the internal surface of the heat exchanger and follows a curved path within the combustion chamber. Except for the open section which carries the exchanger, the boiler furnace is completely surrounded by a jacket for the circulation of heat-transporting fluid.
