I'm asking myself a question about how to warm my house up, and the efficiency of such a thing :
I live in a theater, and we got plenty of 1000W lighting fixture, mostly Tungsten incandescence things, like PAR 64. According to my research on the web, the energy efficiency of those thing is between 3% and 5%. So, if I assume that the rest 95%+ is wasted on heating, that might means they are not far away from typical heaters. Bonus point is, it gives me some light.
But I'm not sure it really works that way.
So the question is : where is really all the wasted energy of a tungsten incandescence fixture really spend on ?
