E=MC2 deals with nuclear physics./reactions. Magnetism is a wholely different but related force.
Electricity and chemistry deals with the (-) electrons circling the (+) nucleus.
A 1500W resistance heater gives off 1500W or 5115 BTU. No more, no less.
The only way to “gain” is to use a heat pump to “move thermal energy”.
These Amish heaters are some of the most refined snake oil I have ever seen.
A 1HP single phase motor drawing 12 amps at 120V. Puts approx 746 watts of power on the shaft, 360W of waste heat blown out the cooling grill. And circulates about 3 amps as reactive power which does no work but heats the wires/windings.
Reactive power is also why small portable generators which “appear to be just large enough”. Won’t run the intended motor, welder etc.
