Abstract (en)
[origin: WO8401206A1] In a hot water tank heated by fuel and provided with an annular compartment filled with water and arranged in a housing, the center of the compartment being traversed by a flue tube (5) heated by burned gas from a burner (7), an annular heating chamber (10) for the water of a heating installation is arranged between the flue tube (5) and the inner wall (28) of the water tank (33). The heating water may heat either the radiators of a heating installation or the inner wall of the water tank if a three-way valve (18) is switched. The temperature of the water which has been used is thereby independent from the heating temperature.
