Sessions
Join your hosts, Cody Harris and Tyler Stevens as they welcome you to Undermine 2025 - the inaugural Heatpunk Summit!
MOD: Cody Harris
Bitcoin mining heat reuse isn’t just a technology shift—it’s a business model revolution. This panel explores how Bitcoin miners can disrupt the heating industry with innovative revenue-sharing models, free or subsidized heating hardware, and new ways to split mining rewards between consumers and service providers. Could this approach create a decentralized, globally distributed mining company? Join us as we break down the economics, challenges, and opportunities of monetizing heat while securing the Bitcoin network.
Cody Harris and Tyler Stevens will kick things off for day 2 of Undermine.

Controlling Hashrate Heaters explores the best ways to integrate bitcoin miners into heating systems. Should they run with simple on/off control or dynamically adjust power to match heat demand? What role do thermostats, sensors, and smart automation play? This panel breaks down the trade-offs between analog simplicity and digital efficiency in managing hashrate heating.

Heating is the goal, but cooling is the challenge. This panel explores the three main heat delivery methods—air, immersion, and hydro—breaking down their strengths, limitations, and trade-offs. Air is simple and direct, immersion captures nearly all heat, and hydro offers efficient heat transfer over distance. But which system is best for which application? And how do you choose the right approach for hashrate heating?
Join hosts Cody Harris and Tyler Stevens for the closing session of Undermine 2025. This interactive discussion will recap key takeaways, tackle pressing questions, and invite insights from non-Bitcoin tradesmen and industry experts in the audience. What are the biggest challenges facing Bitcoin-powered heating? What barriers still stand in the way? What’s working, and what needs to change? This session is a chance to reflect, strategize, and gather real-world feedback to help push the industry forward.
