Aesthetic restoration of the element, it won’t heat anything anymore but it was interesting to understand how it worked.
I must confess that I don’t understand everything … of what I see electricity is taken directly to the heating plates, and plunging rods are electrically isolated from the lid of the boiler with porcelain rings and stacks of mica washers. But nothing else, it means that water is at electric potential … Or while there was an insulator but I can not find any trace?
I thought it could be interesting to take some pictures of an assembly without dressing her up the old lady. Hoping she will forgive me the following:
The bottom, the basins and depressurization of groups grouped together in the same brass manifold. In the middle the arrival of water filling the boiler.
Some details :
Water intake for prebrewing, pipe in the steam for the infusion, and depressurizing at the end of extraction.
