eli5: If most electronic appliances’ efficiency losses are through heat, does that mean that electric heaters are 100% efficient?

Edit:

Many thanks for your input everyone!

Just to clarify, I don’t want to take into account the method of generating electricity or shipping it to the home, or the relative costs of gas and electricity. I just want to look at the heater itself! i.e. does 1500W of input into a heater produce 1500W of heat, for example? Or are there other losses I haven’t thought of. Heat pumps are off-topic.

To add to it… Technically it’s not losses through heat..
Electricity traveling through wires meets resistance.. and the resistance to electricity flow causes heat..

An analogy is when you work hard you get warmer.. the more resistance you have the more “work” electricity has to do and you lose energy due ti resistance and that causes heat..

that in it self is the loss.. ideally there’d be no resistance but we haven’t figured out how to make superconductors at room temperature yet.

There’s no such thing as 100% conversion.. that’s be a perpetual motion machine
