Found out that some people in Finland are using Bitcoin miners to heat their homes now. Like actual heating systems.
So Finnish company SunBit has around 30 of these systems installed. One house in Nokia even disconnected from district heating. The miners heat water for the radiators and earn btc at the same time.
The installation costs around $20k, which is a lot to spend upfront. The company says mining income can cover the electricity bill at current conditions. Then you've got maintenance / mining difficulty going up/ another halving coming in 2028.
Would be interesting how this works out after 3–5 years. $20k is a serious investment, especially when you have no idea what profitability will look like in 2-5 years.
Has anyone here actually tried heating a house with miners? Not a garage or a small room, but the whole house.
