Also a question of optimizing its use
100% efficient!!! You’re using all the energy to do meaningful work!
Setup sponsored by Cyberpunk 2077: Ultimate Edition, to have a real toasting effect.
Isn’t there also visible, non heating light coming off them.?
My oil heater makes gurgling noises so that acoustic energy is lost. It would also just heat up the room eventually, but I usually have a window open in winter so a tiny bit is lost that way.
What about a combination heater/lamp where the lamp part is just incandescence
Power-line losses before your house, so a electric heater is only 96%-85% effecient. When the heating for bird feets is accounted, it’s 100%.
Blaming the heater for losses in the power lines doesn’t seem fair.
Unless it makes a noise or a light that escapes the house
what if you’re running it directly from a generator?
If the generator is inside the house, 100%. But then you could just burn the fuel…
you could just burn the fuel…
Even if the heater’s energy partially is not wasted by a sound, it certainly is by generating magnetic field.
Software engineers fixing a prod-down bug on Friday afternoons operate at 100%
Thanks for giving me flashbacks I didn’t know I had
What about heat pumps they have efficiency in the range of 200-300%
Heat pumps move heat around, whereas radiators create it.
The “efficiency” of heatpumps relates to heat they import into a system for a given amount of power, compared to creating heat with that power. They are not generating that heat. They are moving it.
Similarly, it’s much more energy efficient to use a wheelbarrow to collect ice and move it inside, than it is to make ice cubes in freezer.
Yeah, this is why it makes me irate that my oven automatically turns off the light when I open the door. If the oven is on, let me turn off the light if I want it off. The light and the “waste” heat from the light are both useful.

Any resistance heater, but the most efficient ≠ the most cost effective.
Or light.
Most of the light from a heater is infrared light though, which is absorbed as heat by the surroundings. But yeah a small percentage will be lost as some other wavelengths that might not be absorbed by anything, so it’s not technically 100%, unless you round to 2sf 😅
The air around it will expand and move, too.
More fun than the losses from the heat glow… because can argue if that really is a loss or a feature
What about electro-magnetic losses?
This kid is going places.
Not really, reality will hit him rather hard
It will still lose some energy on the wires.
