## Main Question or Discussion Point

So recently I have gotten in a heated argument with my friend about heating his apartment (no pun intended). Here is the argument:

My EE friend has a theoretical heater which runs on 1000 watts of power. In his apartment he also has another electronic device (ie. a computer, a television ect) which also requires 1000 watts to run. He argues that, due to conservation of energy, 1000 watts is 1000 watts and the same amount of heat will be produced from his "device" as from his heater (and thus if his theoretical device is always running at 1000 watts he will never need to turn out his heater to heat his house).

Being an EE AND a Physics major I disagree with him stating that the 1000 watts of energy is dissipated in ways OTHER than heat. While a heater's primary purpose is to provide as much resistance as possible (dissipating electric power as heat as heat), another device such as a computer uses its power via other methods (not via "heat") but I don't know exactly how to explain it to my stubborn friend (who just keeps shouting V=IR at me).

If I am wrong could someone please justify to me why. And if I am right please provide a good explanation of where the "power is going" so that I may show my friend and convince him that heating his house with a 1000 watt device that ISN'T a heater is a dumb idea.

Thank you,
