Did someone say heat pumps?

Resistive heaters still suck though

• Resistive heaters are much more portable and flexible. (edit: and quiet)
• Resistive heaters are a viable backup when heat pumps fail in extremely cold weather.
• Resistive heaters are less money upfront for if you only have to use them occasionally.

One is not directly beneath the other. Both have their place.

Strictly speaking that's not efficiency, but a coefficient of performance.

And funny enough the work energy doesn't even have to be electricity. It's actually mechanical energy, that is required and you could even power a heat pump with a steam or diesel engine.

A brushless motor only converts ~5% of its input to heat. That's low enough that you can reasonably call it a side effect.

Now, a computer, that's a heater that happens to produce math as a side effect. 100% of its input ends up as heat.

100% efficient!!! You're using all the energy to do meaningful work!

A completely valid pannini press, imo.

Like this is literally the 'modern problems require modern solutions' meme.

I've used older PC battlestations of mine as 'bonus' spaceheaters more than once, lol, sorta like those 'pocket warmer' apps for phones that would just run some absurd computation that would redline the cpu, hahah!

Even sound energy eventually ends up as heat, though!

And that satisfying glow is losses as light, which will do some heating, but not as efficiently

Which travels to a location, hits it and is eventually converted to heat.

When light is absorbed by surface, the material temperature increases and remits light at a longer wave, ussually in the IR spectrum. So its safe to say all light is heat enegry.

Remember: Every device is a smoke machine if you use it wring enough.

Also: Every electrical device is filled with smoke and the job of electricians is to stop the smoke from escaping, which would render the device useless.

Noise would turn in to heat as it’s absorbed, so it’s just heat with extra steps. Same deal with lights

Yup, that little buzz / hum is technically lost energy

Blaming the heater for losses in the power lines doesn't seem fair.
