ABSTRACT:
An electric continuous flow water heater for domestic appliances, such as coffeemaking machines, has a water heating assembly comprising a tubular electric resistance heating element disposed in side-by-side heat exchange relation with a water flow pipe. The assembly is bent into a generally horseshoe-shaped configuration and a heat conductive bridge member extends across the heating element and water pipe substantially centrally of the length thereof and is in contact therewith. A temperature dependent switching means, such as a thermostat or a PTC element, and a thermal safety fuse are electrically connected in series with each other and the heating element are carried on the bridge member with the switching element secured on one side of the heating element-water pipe assembly and the safety fuse secured on the other side of the assembly. The switching element and fuse are operable independently of each other and together form a temperature limiting means to regulate and safeguard the water heating assembly against excessive temperature and excess current flow.
