Electric continuous-flow water heater, with a bare wire heating element, has a temperature sensor extending from the side of the heating block into the water flow to disconnect the electric supply rapidly on overheating

摘要

The electric continuous-flow water heater has a heating block (3) and a heated water flow path (4), with at least one heating element (5). An overheating safety system has at least one temperature sensor, extending from the outer side of the heating block into the water flow path to measure the water temperature directly in the flow.
