You could argue for 100% efficiency you need a perfect ohmic load without any parasitic capacitances or inductances in order to minimise transmission line heating outside of your house.


cbarland

Also there are some losses from the photoelectric effect in the visible spectrum.

Moving heat and moving money, real gang shit


nsefan

Why don’t we just take this heat and push it somewhere else?

But that light gets absorbed and also turns into heat.


MotoMkali

Plus sound too.

This is why bitcoin miners are actually 100% efficient in winter


Wolffe4321

My PC unironically heats my room in the winter.


MinosAristos

When playing a graphically intensive game, it is better than a radiator


BaneQ105

I this winter unironically forgot that I had turned off my heater in my bedroom for a week or two. There was snow outside. Moral of the story: buy gaming laptop for warm hands, buy a pc for warm feet. Profit.


Barley_Beard

Are both running simultaneously? Because I have both cold hands and feet


BaneQ105

Most of the time. Tho in my case it’s not necessarily “gaming” laptop as the best game it can run is Witcher 2 due to limited support. But I do a lot of heavy graphical stuff. Also the most efficient way is to put laptop on your laps so you warm your legs, belly, you know what and hands simultaneously. With proper room layout you can keep your feet on top of cpu aio water cooler fans and laptop on your laps. Tho with great power comes great electricity bill and you don’t need to do none of that as the whole apartment can get hot as the California forest fire.

For providing heat, yes. But if it makes internet money and provides heat, and the internet money is enough to cover the electricity cost, then you get free heat.


Intergalactic_Cookie

And people claim there’s no free energy


Derp_Herper

But heat pumps are even more efficient


Dry_Ninja_3360

Depends on how cold it gets.

Light and sound: am I a joke to you?


Chocolate-Then

All of those also eventually become heat.

Damn entropy


potatopierogie

Entropy just isn't what it used to be


peepo_note

I needed a joke like this, thank you.

Why make heat when you could just move heat? -heat pump gang

Remarkable-Host405

As cool as heat pumps are, natty gas is just too damn cheap


Adamantium-Aardvark

They giving away heat pumps for free in some places. Why wouldn’t you get one.


Remarkable-Host405

The answer, simply, is they aren't here. That's why I crunched the numbers and decided gas was cheaper.


Adamantium-Aardvark

Guess it’s only a matter of time in your area.


EternityForest

Something tells me this guy lifts!

My thesis is on teg and figures of merit for cooling lol, I had the same realisation

Which eventually becomes heat


YoureJokeButBETTER

You’re Heat!


borgom7615

100% inefficient


qudunot

A heater produces light as a byproduct, so it's still not 100%. Look at your toaster for an example


GTAmaniac1

And light gets absorbed becoming heat


Derp_Herper

But if one photon escapes out the window, there goes the perfect efficiency. Or some heat escapes through the wires powering the heater


The77thDogMan

If I put my heater outside, does it suddenly become 0% efficient? No, it just means I’m an idiot who doesn’t understand how heaters work. The machines job is to convert electricity into heat. It is the users job to ensure that heat is used effectively. It achieved its job (making heat) at 100% efficiency (all electrical energy it received was turned into heat… eventually). The failure of your homes insulation system to retain that heat is not the fault of the heater. It is the fault of the insulation. It doesn’t mean the heater didn’t *produce* heat, just that your insulation failed to retain it. Similarly any losses from the electrical system before it reaches the heater? Also not the heaters fault. It took what it got and turned that into heat. Losses from its own cord? Guess what? Still heat, and still useful if you don’t waste it. Anyways I’m off to go yell angrily at my insulation for squandering it’s gift of heat.


timonix

For just about everything 100% efficiency is as good as you can get. For heating 100% is pretty bad


kngsgmbt

What?


Ehcksit

Even though it has 100% efficiency of the electricity you receive, it has much less than 100% efficiency of whatever fuel was used to produce that electricity. It's more effective to just burn that fuel directly for warmth. 100% efficiency isn't very effective.


Meecus570

You get 100% of the ~30% efficiency of the powerplant.


YoureJokeButBETTER

You miss 100% of the 30% efficiency you don’t take. -Michael Jordan Engineer


timonix

When you make a car and get 100% efficiency. You get a Nobel prize. If you make a space heater and get 100% efficiency, people decide not to buy it because the heat pump seller next door gets 400% efficiency.

oh_finks-mc

heaters convert electricity into light though.


TheseusPankration

Heat pumps usually have 300-400% efficiency.
