ABSTRACT:
A fuel heated hot water storage tank with a water filled annular space (33) is disposed in a case (1). The center of the annular space is provided by a flame tube (5), which is heated with the waste gases of a burner. An annular heating space (10) for water of a heating system is disposed between the flame tube (5) and the inner wall (28) of the water container (33). The annular heating space (10) is formed as a double annular space in the shape of a U, where the two arms (11, 12) of the U are connected to each other in the lower region (34) via a redirection connection (14). A further annular space (26) is provided between the outer annular space (12) of the double annular space (10) at a heat insulating distance (27) from the outer annular space and the further annular space is located in a heat conducting connection to the water filled annular space (33). The heat insulating distance can be provided as a third annular space (27).
