Does any one remember the electric plate warmer? This was a glass topped panel, about 2 ft long with an electric circuit to warm up the glass, plus a hot plate, to keep your food warm.
Similar to what my Auntie had, the Philips Hostess Europa was unique amongst Hostess trollies in that it did not have the usual glass dishes in the top but a heated glass plate instead, this allowed you to use any dishes you liked on the top and was very effective, you still had the hot cupboard below and they were individually switched.
And those Belling heaters that could also be used as a water boiler, about 1M tall and had the usual fireglow bulb in the bottom. The Belling Champion.
and to expand on that the electric 2-3 bar fires with the plastic coals/wood lit by a fireglow bulb.
