Since August 2024, our first site in Finland has successfully delivered heat to 15,000 residents while mining a good chunk of bitcoin at a low cost. We will launch our second such district heating mining site in May, with plans for several more over the coming year.

Bitcoin mining can be integrated into the heat production stage of this cycle. Hydro-cooled machines, particularly the WhatsMiner ones, generate hot water that can be pumped into the large water tank of the district heating plant. The district heating plant buys the heat from the bitcoin miner and delivers this heat to its district heating customers.

It is important to note that bitcoin mining cannot provide 100% of the heat to a district heating plant, but more like 20%. This is due to the significant difference between heat demand in the summer and winter. Bitcoin mining can provide constant baseload heat (the lowest heat demand over the year) but during the winter, when heat demand increases, the district heating company must still fire up its fuel-powered boilers.
