Abstract
A continuous flow heater has an elastic, flexible or rigid pipe (,) which is movably mounted and a heat source (,). When a liquid flowing through the pipe is heated in the pipe interior (,), undesired scale tends to be deposited on the interior of the pipe walls. To prevent or remove this deposit, the pipe (,) is moved and/or deformed by an internal overpressure or by application of external forces, causing the deposits to be detached from the pipe inner walls and carried away by the fluid flow. The overall pipe (,) can have an inner pipe (,), inner insulating layers (,), a filament (,) and external insulating layers (,).
