ABSTRACT:
A thermosiphonic boiler with two mutually communicating water containers, one above the other, said containers housing water volumes being thermically insulated from the surroundings of the boiler and from each other by heat insulation in the boiler walls and in an intermediate wall common to the containers and separating their water volumes. The lower container is incorporated in an energy supply circuit through which water from the lower portion of the container is caused by a pump to flow through a solar radiation trap heating the water passing therethrough, and back to the upper portion of the lower container. The upper container is connected to a circulation circuit through which water from the upper portion of the container is returned by means of a pump to its lower portion after having passed through radiators. In the water volume of the upper container there is provided a hot water supplier with heating means from which supplier hot water can be tapped off. The intermediate wall constitutes a pressure vessel preheating fresh water supplied to the hot water supplier, there being provided in the intermediate wall a central pipe stub extending through the wall, through which pipe stub, water from the upper portion of the lower container can flow by thermosiphonic action up into the upper container, there being provided at the circumference of the intermediate wall openings through which water from the lower portion of the upper container can flow down into the lower container.
