Sharp question. You're absolutely right—heating an unused garage is just burning money.

To clarify: I built a simple ducting setup to divert the exhaust air from the miner into my basement workshop, which is connected to the house's insulation. It's not 100% efficient, obviously, but it takes the edge off the main heater during the coldest weeks.

If I were just warming the garage itself, you'd be right—it would be pointless. Thanks for keeping me honest though, details matter! 🫡
