Adam, a QA engineer at Braiins, heats his entire house with a single hydro-cooled bitcoin miner. The system provides floor heating, hot tap water, and earns bitcoin at the same time. It has been running for over a year.
Q: Who are you and what is your background?
I work as a QA engineer at Braiins. I grew up learning from my father, an electrician, which gave me hands-on experience with electrical work from a young age. When I started working at Braiins, I knew that when I build a house, it will be heated by hashrate.
Q: What do you think about bitcoin?
I think and dream only about hashrate.
Q: Why did you decide to build a hashrate heating system?
Heating was the top priority for my new home. I worked with a project engineer to design the house so that mining heat reuse fits into the overall heating concept. The requirements were similar to a heat pump setup: low-temperature floor radiant heating throughout the house. Lower water temperature means better efficiency, whether you use a miner or a heat pump. I built only the miner loop myself. The tap water loop and floor heating were installed by a certified plumber.
Q: What is your view on mining heat reuse and its future?
Hashprice is getting lower and margins are shrinking. Heat reuse will become more important over time. It is sustainable, works well with grid balancing and curtailment strategies, and helps bitcoin mining become more decentralized.
How to Plan a Bitcoin Mining Heating System
Q: What resources did you use during planning?
I researched across forums, Reddit, Twitter, and YouTube. I studied two-phase cooling, immersion cooling, and eventually settled on hydro cooling. I combined general knowledge of thermodynamics and hydrodynamics with what I call "the method of trial and error" and continuous improvement.
Key resources and communities:
- HeatPunks.org and their forum
- CoinHeated on YouTube
- Home Bitcoin Immersion Mining on YouTube
- Chinese hydro cooling manufacturers and their documentation
- Russian and Indian YouTube channels covering DIY cooling setups
