26kW sounds awesome for mining - assuming you know how to cool it all down.
I have hard times dealing with 3kW of heat in a large basement.
Is there any feasible way to reuse the heat to save on oil/gas/water heaters?
Only if you capture the heated (with a range hood / box and suction fans) air and feed it into your furnace inlet to be filtered and humidified .. else it's not that funny to run your rig in the living room because of the eventual noise.
Haha, this is awesome, you guys read my mind. This is a pre-con house so I was there when they installed the hvac system, and I asked a lot of questions. My plan is to funnel the heat from the miners into the main return. But I've got to power them first.
