Rod Speed's got it. Actually, the problem with a Resistance Heater is that
it's much more wattage and has a, comparatively, miniscule hot spot with no
buffer or heat exchanger. Even at 1500-watts a Resistance Heater Is only
effective for close proximity and takes very long to heat up a space's items
(heat soak), due to its lack of Volume Heat.

If he does something like the video with glass instead of ceramic, he gets
both light and heat by creating a heat exchanger...where mostly just the
outside surface heat is blown off but not much of the heat source is depleted,
creating a constant provision of steady heat. If he needs to adjust to lower
and higher demands, he just removes or re-installs bulbs (or unscrews
partially, if he opts for that convenience).
