Few of us know that resistor load isn't as "hot" as cartridge heater load. As well as design of load block itself can change the result quite a bit.

"Energy can be neither created nor destroyed", first law of thermodynamics.

If you put in 200 watts somehow 200 watts either comes out completely or part gets held my the mass as latent heat, but as 200 watts is feed continuously the latent heat will reaches a maximum for that substance and 200 watts will exit. minus small energy losses in other thermodynamic areas.
