Filter coffee maker - heater element.
 

Is there any standardisation on the heater elements on filter coffee makers?

Of the 2 I took to bits, both had almost identical horseshoe shaped elements
clamped underside the hot plate with the water tube welded on below that.

On reflection - I have a couple of paper filter types that have no drip
valve, so I'd have to wait for it to finish perculating before I can take
the jug out to pour coffee, I might have been able to nick the element out
one of those to fix my old favourite with nylon filter & drip valve.
