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?
You are missing a key part of the equation. the "work" is how the electrical energy is transformed to heat. Check Klondike bar's comments too
