We have 3 S9s heating our house. I am very surprised how well they heat our house. It is actually warmer than with just our heat pump. It has to get to about 30 degrees F for our heat pump to run for any length of time.

Going through the process of setting up miners to heat up my home and water tank, right now. However, I keep wondering whether it would just be better to buy more sats, instead of investing in the home heating.
