Beschreibung
Zusammenfassung:	Electrical heating apparatus includes an electrical heater in which the inlet conduit for inletting cold water to the electrical heater and/or the outlet conduit for outletting hot water thereto from the electrical heater is integrally formed with a pressure-responsive device which senses the flow rate to or through the electrical heater to control the energization of the electrical heater. The apparatus also includes a regulating valve constituted of a membrane and a stem having a head of convex configuration facing the membrane but normally spaced therefrom to define a flow-control passageway which creates differential pressures acting on the membrane tending to deform the membrane such as to maintain a relatively constant flow rate through the flow control passageway despite variations in water inlet pressure.
