With the large variety of electric space heaters out there purporting to be the "best, and most efficient" such as the Eden Pure, and others, I cannot for the life of me see where one is better than another. Watts is watts, right? P=EXI every time? I don't think the power usage is more or less efficient from a 1500w $40.00 space heater using a standard resistance heating element OR the Eden Pure ones using the same wattage but using an infrared tube... (or something similar)... Anyone help me out here?
I would give you that a radiant heat one one might be more efficient that one using a fan, but only by the wattage of the motor...

Thanks very much

You are correct.

They are all about the same efficiency of 100%. The only way I know to go over 100% efficiency is with a Heat Pump and that's because its not making heat but just moving it (aka a transfer engine).

I agree...
Heat pumps are the only thing I can think of that give more than a dollars worth of heat for a dollars worth of electricity.
Problem is, advertisers bamboozle people into thinking otherwise.
Thanks for the answer, it reinforces my thinking.

Yes, just open the Sunday paper's Parade section and you'll see a ridiculous add about Omish electric heaters. I agree the Omish have some things correct, but they really shouldn't hitch their wagon (no pun intended) to this nonsense.

Interestingly, my father-in-law is an electrician and my mother-in-law seems to think their electric space heat they just bought is saving them gobs of money. Even well educated people forget the laws of physics just cannot be broken.
