I can’t tell if you’re agreeing with me or contradicting me.

If you agree, ignore this, if not, here’s the explanation:

Electric heaters are the only things that are 100% efficient. All other devices lose energy by putting off heat. A motor turns but coils heat up for example so that’s wasted energy. A heaters purpose is to convert electric energy to thermal energy. There’s no other form of energy that it puts off as waste.
