Throughflow electric water heater - has heating body surrounding, or surrounded by, parallel throughflow pipe(s)

摘要

Electrical throughflow heater has throughflow pipe(s) and an electrical heating body, parallel to each other and in heat-conducting mutual connection. The wall of one of these functional elements is constructed such that it receives at least one further functional element and/or partially surrounds it. Pref. an endless profile is used, as a double or multiple pipe, whose wall parts act directly as jacket for the electric heating body, and which has a shaped-on profile shank(s), which may be L-shaped, with two shanks and the wall forming a U. No welding or soldering is needed.
