No, my miner heating situation is much less sophisticated, I just point the exhaust from the miner in the direction I want the heat. Sometimes into my furnace ductwork, sometimes directly into the room. There was some discussion around using the miners to heat mass during the day running on solar to take advantage of the heat at night while the miner was shut down. That is an interesting concept. I'm thinking the best way to store heat from a miner would be in water not cob or concrete.
