I have heard that story too, just check the water level now and then
to assure you donĀ“t run the amplifier dry.
Good engineering practice? probably not but the plate will not reach higher
temperatures than 100C :-)
------------------
Surely all it needs is a couple of level detectors, one as a reminder to top
up, the other at a lower level as a shut off. A small fan and tumble dryer
ducting will blow the steam outside. With a small outlet funnel well above
the water level, timing the pouring right should ensure that you can't have
a continuous stream of water between the anode and the top-up jug.
What does it do the the anode C?
