No, I haven't. Would you care to explain further?

Well when I was there in the 1970s the kettles just had bare nichrome
wire elements directly in the water - i.e. "immersed and uninsulated
heating elements". Some current doubtless flows through the water, but
the main heating effect is still from the passage of current through
resistance wire.

And, surely, an electrode heater fits the description perfectly?

An electrode boiler has no element as such - it just has electrodes.
Current is persuaded to flow directly though the water (or other working
medium), presumably by the use of chemical treatment to increase the
conductivity. Thus the medium is heated directly instead of by the
conduction and convection of heat from a hot metal element.
