I’m curious about what you’re thinking of, but for both electric heaters and computers, essentially 100% of the input energy is converted to heat one way or another.

What you may be thinking of is efficiency when the output is intended to be something other than heat. In those cases, efficiency is lost because a significant proportion of the input energy is converted to heat.

But if heat output is what you’re interested in, I’m happy to report that 100% is a perfectly achievable, in fact hard to avoid, number!

Where the heat goes is the problem I have with that rating. An electric resistive stove is 100% efficient at converting input electricity to heat, but an induction stovetop is far better, better even than gas, for cooking on.

Yeah, i was totally confused with efficiency, still curious about that 0.01% now tho

There will be an LED somewhere, so some of it gets converted to light, rather than heat.

Light is a way of transferring energy, that ultimately translates into heat.

Essentially, light is one of the principal agents of entropy.
