It is the same in every single field of science, every technology out there, every application of physics really. Energy in is always equal to energy out, no exceptions, ever.

Then here is an interesting enigma for you. I've worked for a company for almost 33 years that makes water chillers. They are used to chill water to about 40 to 44 degF to use in airconditioning systems (sort of the opposite of hot water boilers for heating). On average, these water chillers use about 600 watts to produce 12,000 Btu/hr of cooling energy (heat removal). At 3.413 btu/hr/watt (conversion factor), that's 600 X 3.413 = 2048 btu/hr of input energy. 12,000 btu/hr is output energy.

So 12,000 / 2,048 = 5.86 COP. So I get 5.86 watts out for every watt in.

As an engineer, I can undeniably state this is a fact. The same unit can be used to heat instead of cool and it will output 3 watts of heat for every 1 watt of input energy from electricity. COP is about 3.0. Boilers have a COP of about 0.85 (85% efficient). So I can produce heat from electricity 350% better than a boiler that's 85% efficient.

So is there a flaw in your thinking or ?

In the absence of that which is not, that which is, is not.
