Guys, I'm having a private debate with someone about heating a room with miners. The argument is that a 1000w water cooled miner won't heat a room as much as a 1000w air cooled miner would.
1000w input = 1000w of heat no matter how it's cooled. Correct?
The 1000w has to go somewhere energy can not be created or destroyed only transformed. You are correct.
Not sure I agree. Energy cannot be created or destroyed = true .But my argument is that the 1000w of electricity does NOT have to all be converted to 1000W of heat. In fact, it CAN'T all be converted to heat or no other "work" could be done by the miner....so the more efficient the cooling, the less of the 1000W is needed for cooling = the more electricity available to get converted to "work". Assuming that the watercooled miner is more efficient at cooling than an air cooled miner, it is a "worse" room heater. Make sense?
work is energy. 98.5% of the power used by the miner is emitted as heat, ~1.5% is emitted as light or sound, and ~0.05% is electrical signals carrying data back to the internet.
the only difference is that air cooling may more effectively transmit heat to the opposite end of the room whereas the radiator may have a hot pocket of air around it if the fans arnt as powerful
