106. High Signal in the Hashtub: Workshops, Open Source, and Hashrate Heat

In this episode, we debrief the second annual Heatpunk Summit from the legendary Hashtub in Denver. We recap how builders from HVAC, hydronics, and home mining came together to advance hashrate heating—complete with live hardware demos, workshops, and a brutally constructive critique of our boiler setup from a pro hydronics engineer. We dig into galvanic corrosion gotchas, smarter system design, and why practical, hands-on education is the real unlock for bringing Bitcoin miners back into homes and businesses as useful heaters.We also break down the big development with Canaan’s openness to support the home-mining and heat reuse market, what a “willing partner” ASIC manufacturer could mean for decentralization, and how small improvements—docs, APIs, and integrations—can catalyze a whole ecosystem. From workshop highlights (Home Assistant control, hydronics integration, open-source mining OS, and regulatory/insurance insights) to the industry’s AI pivots and the investability of open source, this is a high-signal builder’s recap with clear next steps and renewed momentum for hashrate heating.
