not 100% of the electricity is converted to heat, i guess some is lost to ground

Heaters don't have 100% efficiency. Some of the energy is converted to light and/or physical deformation.
Unless you're talking about a heat pump. But that has way more than 100% efficiency.

Every device ends up putting some energy into stuff that you don't want.
A heater, an incandescent bulb, and an LED light all convert electrical energy into photons. The heater converts most of its energy into infrared photons that we harness to heat things, but it also converts some of its energy into visible photons that are a waste. Conversely the LED light converts most of its energy into visible photons that we harness to illuminate things, but it also converts some of its energy into infrared photons that are a waste. And the incandescent bulb is somewhere in between.
You're always losing *some* energy to *something* you don't want or need.

My oil heater doesn't emit visible. Visible light is absorbed by atoms (depending on energy level etc) which raises the temp anyway. I don't see how we lose something when that 'unwanted' loss makes heat eventually anyway.

This and some of the heat heats the heater instead of the thing to heat.

You can't "convert" to heat. Heat is a transfer of energy. You meant both eventually convert to thermal energy.

This device has over 100% efficiency. It has achieve the fabled and long thought impossible over unity!!
What is this mystical device? It's a water heater. It's just a metal drum with holes bored into it so when spun inside water it produces supercavitation which generates tons of heat. I showed /sci/ this many years ago and they were forced to agree it is indeed over 100% efficient but that's only possible because it is producing heat.

I think this also produces sound that dissipates to the surrounding. and the air friction too. So it doesn't put all of the possible heat energy into water only.
In room heater however, any losses will go to the air in the room thus heating the room.

It's not over 100%.
There is no way to use the heat it generates to power itself for an infinite length of time

Wrong. It is over 100% because it is not converting free energy into heat but using free energy to move heat. The coefficient of performance can easily reach 350% even for commercial applications.

Measure how much energy you put in. Measure how much comes out.
Notice the loss.

A bitcoin mining heater, or any heater that does useful work has more than 100% efficiency because you use the most of the energy twice.

But to be a efficient bitcoin miner, the device should be cool enough, which means it's not a good heater. Conversely if you try to make it a good heater, the bitcoin mining will not be effective because device may break down. So my speculation is that the bitcoin mining heater could be 50% efficient at max.

The miner is cooled by heating your house. That's exactly how a heater functions. The chip needs to be around 100 F. How often do you heat your house to more than 90 F?

No because heat would be a mimic of fire producing heat which means it's potentially only 75% a mimic of fire and heaters are bad for you due to this.

if you think that’s cool wait until you hear this: if you use your refrigerator to heat your home, they actually have >100% efficiency; they output more heat than they consume in energy.
