no, I need the temp of the heating element be no higher than ~50C.Ohhhh ...I get it. It's hair dryer design..
Phil, would please leave the subject line alone, eh?

water soluble.
Phil said:** I have already described how to do that ( with a link to the needed
power resistors) with complete safety.

I am building a compact air heater as a hobby project where the air is
blown between fine fins of several aluminum heat sinks. The
temperature needs to be raised from ~0C to ~37C and needs to handle
air flows of up to ~100 L/min. I did an envelope calculation taking
into account heat capacity of dry air, and it appears that I would
need ~100W, 300W to be safe, for that.
So I want to run a nichrome wire in a spiral pattern along the surface
of the aluminum heat sinks. But wouldn't that cause a short? Can I get
insulated nichrome which would conduct heat, but not conduct
electricity? Any suggestions?

Thank you, Tom,
What I have described probably indeed looks like a hairdrier. However,
hairdriers quickly heat air in a small package because of heating the
wire to a very hot temperature (don't know how hot, but the wire glows
with infrared). In my case, I want to avoid using high localized
temperatures due to safety concerns. So the idea was to re-distribute
the heat over a large surface, and thus being able to use lower
temperatures.
^ That's apparently the end view.
Here's the side view: ---------------------
The insulation is perforated, of course, to allow better heat transfer.
