Abstract (en)

[origin: WO0198716A1] Hot water boiler with a flow heater for tap water, comprising a combustion chamber (4), an outlet for heating water from a gap-shaped passage (22) arranged around the combustion chamber (4), a tube coil (18) for tap water arranged in said passage, and an inlet (9) for return heating water. The boiler comprises a preheater (11) for return heating water arranged in the combustion chamber (4). The preheater has an outlet line (13) which conducts preheated heating water out of the combustion chamber (4) to the lower part of the boiler, from where it passes upward in the gap-shaped passage (22) surrounding the combustion chamber (4) while being heated by the combustion chamber (4) and transferring heat to the tap water. A high production of hot tap water is thus achieved.
