A community working on the emerging hashrate heating industry - Marrying the bitcoin mining and heating sectors to bring hashrate back home | @256Foundation
Open-source mining is the future. And the work has already started.
Keep up with our progress on https://t.co/1rl8PXdMZu
Thank you to the MARA Foundation and all of our supporters.

BITCOIN RAILS #57: BITCOIN MINING HEAT REUSE + HEATPUNK REVOLUTION | with @tylerkstevens

Tyler Stevens—author of Bitcoin Mining Heat Reuse and a leading voice in the space—joins the show to unpack the growing “heatpunk” movement in Bitcoin mining.
Traditionally viewed as a drawback, excess heat from mining is being reframed by heatpunks as a valuable feature, e.g. to generate useful heat—like home heating or hot water. Use for these heat byproducts can effectively subsidize the cost of Bitcoin mining—making operations significantly more profitable, or even free, while contributing to higher hashrate and a more decentralized network.
As Stevens puts it, “Heat reuse solves the security budget problem.” With block subsidies declining over time, mining incentives must evolve to remain sustainable. If Bitcoin mining can serve a dual purpose—securing the network while also fulfilling real-world energy needs—it has a path to long-term profitability, even in a low-fee environment.
In this episode, Tyler and I discuss:
- What “Bitcoin Mining Heat Reuse” is and why it’s shaking up both solo and industrial miners’ thinking
- The different ways heat from Bitcoin miners can be used
- What the long-term impacts of mining heat reuse could be in the face of a dwindling block subsidy
- How Bitcoin mining could change the economics of the global heating industry
- What the impacts of heat reuse could be for megaminers and miner centralization

Dylan and I are working to make bitcoin miners smart home IOT devices.
For hashrate heating. For solar monetization. For profitable mining when power is cheap.
This requires connecting miners to other devices.
Home Assistant was the missing link. Here's @tronsington's demo!
Heatpunk gadgets (space heaters) are known and loved.
But heating appliances aren't as simple. Integration comes with hurdles.
Eng drawings, inspections, BMS control, service, repair...
Architects and Home Builders had a lot to say about buildings that heat with hashrate!
After the 2026 Heatpunk Summit welcome remarks, I set the stage for our second conference with a brief keynote about "defining an industry".
Check it out below.
Heatpunks range in scale.
Larger applications require so much heat, bitcoin mining heat-reuse reflects normal mining ops in many ways.
Full uptime, industrial rigs.
But it's not all that simple.
Great insights from @khalliburton@bitcoinbaseload@Colin_Sully@csartoshi!
The 2026 Heatpunk Summit kicked off with an excellent panel highlighting hashrate heating product development.
Space heaters, water heaters, hydronic boilers, hot tubs and more - lots of development over the past 12 months!
