Abstract

Offenbart ist ein elektrischer Heizblock für einen Durchlauferhitzer, mit einem Gehäuse, in dem ein Strömungskanal zur Definierung einer Heizstrecke für ein Fluid ausgebildet ist und in dem Heizelemente zum Erhitzen des durch den Strömungskanal strömenden Fluids anordbar sind, sowie mit einer Durchflussbegrenzungseinheit zum Einstellen eines Durchflussquerschnitts, wobei die Durchflussbegrenzungseinheit in das Gehäuse integriert ist und mit einem Ventilkörper zumindest abschnittsweise in den Strömungskanal eintaucht.Disclosed is an electric heating block for a water heater, comprising a housing in which a flow channel is formed for defining a heating path for a fluid and in the heating elements for heating the fluid flowing through the flow channel can be arranged, as well as with a flow-limiting unit for adjusting a flow cross-section, wherein the flow-limiting unit is integrated into the housing and with a valve body at least partially immersed in the flow channel.

Die vorliegende Erfindung eignet sich insbesondere zur Bereitstellung eines elektrischen Heizblockes für einen Durchlauferhitzer im Bereich der Hausgerätetechnik, der kompakt, robust, einfach zu installieren und kostengünstig ist.
