A user on the “Habrahabr” forum, nicknamed teamtimteam, integrated a Bitcoin miner into his home heating system and now earns a net profit of about 23,000 rubles (~$250) per month.

A Year of Development

The enthusiast, working with an engineer colleague since 2023, read up on hydrodynamics, consulted plumbers, and created 3D models for the future installation.

In November 2023, he purchased an Antminer S19 Hydro 151 TH at 135,000 rubles when Bitcoin was around $38,000. Additional components cost 29,000 rubles, bringing the total “crypto boiler” cost to 164,000 rubles (~$1,800).

At the time of purchase, the setup brought in 35,000 rubles a month, with electricity costing 12,000 rubles, resulting in a 23,000-ruble net profit.

Extending to a Sauna

In 2024, teamtimteam built a bathhouse and equipped it with a more powerful Antminer S19 Hydro 198 TH.

“This project wasn’t just a cost-saving measure; it was a fun experiment combining technology with everyday life. My home is both heated and profitable,” he concluded.

Analogous Projects

Ukrainian Bitcoin enthusiasts at Hotmine have been marketing similar devices since 2013.

In April 2024, Finnish company Hashlabs Mining introduced a plan to use heat from Bitcoin mining for residential heating. American mining firm MARA has launched similar projects in Finland.

In June 2023, Bathhouse in Brooklyn disclosed using heat from ASIC miners to warm its pool water—customers reacted with mixed feelings.
