Abstract

A flow heater is described that has a housing in which a flow channel extends from a liquid inlet to a liquid outlet. The heater has a metal plate along which the flow channel runs, and the metal plate carries a heating resistor. Provision is made for the metal plate to carry a corrugated sheet that protrudes into the flow channel and has openings through which the liquid that is to be heated can pass.
