Yo,

Has anyone here any practical experience with suspended IR (electric)
heating, as you often find in commercial settings?

A friend works in a large workshop area (probably 40' x 40') with a
low ceiling half (under a mezzanine floor) and the other half goes up
to the (steel) roof. Little or no insulation anywhere (and no chance
of fitting any) so I was thinking IR 'person' heating might be the
only viable solution above the bigger open area, really to just make
it more comfortable to work in there, rather than make it warm?

This was solution was considered after going into some of the big
d-i-y sheds and sensing heat on my head and when looking for the
source, seeing the long radiant heaters some 30' above me!

Mind you, we can feel the IR radiation from the sun and that's ~90
million miles away! ;-)

So, can anyone recommend it as a solution for this sort of role and
suggest any specific heaters / suppliers please?

Cheers, T i m

standard stuff where heating the space is unworkable.

Do you mean IR heating in general or overhead specifically?

IR. Which is usually placed overhead in work spaces.

Do the lower level flat IR panels radiate as well and the ones that
actually glow red or are they more like convection heaters?

IR radiation comes from high temp emitters. Dark panels won't do it.

Gas is of course several times cheaper.

Of course but not if you have to have it installed in the first place
and the electricity usage fairly low (people not in the workshop 8
hours a day etc).

Working under that isn't comfortable, but it beats no heat by far.

I guess that's the trick, getting the warmth down near the floor but
without being too hot on yer head.

that's where overhead IR heating fails. Cold feet & burnt head. But it sure beats no heat.

Maybe 'several' smaller units might be better than one big one in that
regard?

Cheers, T i m

Yes. Maybe the OP could buy a pile of filament lamps.
