Abstract (en)

[origin: WO9641994A1] The instantaneous water heater of the invention consists essentially of an elastic, flexible or rigid, floatingly fitted composite pipe (10) and a heat source (6). When the liquid is heated inside (1) the pipe, undesirable substances, e.g. chalk, can separate out from the liquid and be deposited on the inner walls of the pipe. If, however, the pipe (10) is moved and/or deformed by internal overpressure or external force, the separated substances fall off the inner walls. The composite pipe (10) can, for example, consist of an inner pipe (2), internal insulating layers (3-5), a heating wire (6) and outer insulating layers (7-9).
