Sticking a heater near the ceiling is not an effective use of energy.
Yes,
they are widely maligned because using 'lighting' as a source of heat is
stupid. The heat is in the wrong place and its made using a particularly
inefficient method.

The 'old' incandescent Gas lights were certainly very effective as a heat
source in my youth - - before ceilings were insulated, too.


Yes, gas burned in the house has c100% efficiency at producing light+heat
(though the heat _was probably in the wrong place_). However, burning gas in
your not-so-local power station to produce electricity at +/- 50% efficiency
(which then produces 20% light and 80% heat (in the wrong place)) is not the
best use of energy.
