It's a fact covered in most undergraduate electro-magnetic physics classes.

It is also true that electric heat is more expensive than most other forms such as gas or kerosine.

I'm excluding Quartz since its not efficient for the use at hand.
Thanks all. ;-)

Entropy...everything turns to heat, one of the easiest transformations to make.

Some heaters emit a bit of red light.

I agree about quartz tube heaters. Everything stays cold except the things you want to stay cold. I favor the ceramic heaters myself. Get something that won't burn the place down, and preferably isn't too huge.
