House in Finnish city of Nokia switches from district heating to a bitcoin miner

A house in Nokia leaves the district heating network

A private house in the Finnish city of Nokia has been taken off the district heating network and is now warmed by a machine mining bitcoin, according to a ForkLog report published on 10 November 2026. ForkLog said it was citing CoinDesk.

The house has an area of 180 square metres, the report said. District heating, common in the Nordic countries, produces heat at a central plant and pipes it to buildings; the owners gave it up entirely, according to ForkLog. Nokia is the city that gave its name to the phone manufacturer.

The replacement is an ASIC miner. An application-specific integrated circuit is a computer built for a single job, in this case the calculations that secure the bitcoin network and earn the operator newly issued coins and transaction fees. Mining hardware draws electricity and releases much of it as heat, which is what warms the building.

What the reports do not say

ForkLog's summary gives no figures for the machine's power draw, the price the owners pay for electricity, the cost of the installation or the amount of bitcoin it produces. It does not say whether the house keeps a backup heat source, or whether any authority was involved.

The owners are not named in the report, and no comment from them appears in it. It is also not stated how the running costs compare with what the house paid for district heating.
