I am making this garage heater so that working in my garage is less
painful in winter. It has a 9.6 kW heating element. I made some
photos, some with flash and some (out of focus) without flash. The
ones without flash make condition of coils a little more visible.

The heater is not done yet, it needs a few extras, although it is
working. The case that it is in is a case from an old "die attachment
evaluator".

My question is, are the coils too hot or not. Any ideas?

Too hot! You should not see any bright red glow! Perhaps just a very dull
red, barely observable in spots.
Iggy, those coils are made to be installed inside a duct, just a bit larger
than the coils. You need to get a bunch more air over them!
run down to home Depot, Menards, or Lowes and pick up a piece of duct large
enough to get 1/2" to 1" of clearance from the coils, on all sides, attach
your fan to the end of the duct, and try again.
I still think the fan is too small!
