High-temperature heat reuse converts compute waste into scalable district heating infrastructure 
Project provides additional validation of Canaan's expansion into energy-integrated compute infrastructure

SINGAPORE, May 19, 2026 /PRNewswire/ -- Canaan Inc. (NASDAQ: CAN) ("Canaan" or the "Company"), an innovator in crypto mining, today announced that it has been selected to support a district heating network in the Nordic region.

The heating solution, developed in partnership with a leading Nordic heating provider (the "Customer"), utilizes Canaan's advanced Avalon A1566HA series hydro-cooled units with a combined capacity of approximately 8 MW. These units, engineered to deliver high-efficiency thermal output directly into local heating networks, will replace traditional heating solutions currently used by the Customer.

Canaan's proprietary semiconductor and system design technology, capable of producing high-grade hot water at temperatures of approximately 80 degrees Celsius, facilitates the direct integration of high-density compute infrastructure into existing district heating systems. Following an evaluation of competing solutions, the Customer selected Canaan's equipment for this second phase. Approximately 2 MW of heating capacity, comprising 228 A1566HA units, is currently operating in the region, reliably providing hot water to local residents. Building on this performance, the Customer placed a follow-on order in March 2026 for an additional 6MW of capacity, comprising 692 A1566HA units.

Canaan's A1566HA hydro-cooled miners, operated by the Customer's team, contribute thermal capacity while maintaining operational flexibility across varying demand profiles. Because the heating nodes consist of numerous parallel A1566HA units that support dynamic overclocking and underclocking, they deliver greater stability and reliability than traditional single-source heating systems such as boilers. This parallel architecture also makes maintenance easier and enables more consistent hot water supply along with optimized power-to-heat conversion efficiency.

Governments and municipalities often incentivize district heating solutions because they enable efficient hot water distribution across urban and regional networks. This approach helps address a long-standing challenge in hash-to-heat — delivering usable high-grade heat at scale — which has proven difficult for many players in the industry. With this challenge now being effectively addressed, Canaan believes hash-to-heat solutions will accelerate the replacement of legacy heating systems, including outdated fossil fuel-based solutions that are long overdue for an upgrade.

"This selection reflects both the strength of our technology and the depth of our engineering knowledge," said Nangeng Zhang, chairman and chief executive officer of Canaan. "Heat reuse is no longer an ancillary byproduct of compute.  It is central to building a more efficient, sustainable energy future, and a core part of how we think about system design at Canaan. I was closely involved in the research and development of this platform and personally led the design of its form factor, focusing on optimizing thermal performance and deployment efficiency. We developed this solution with the specific requirements of modern district heating infrastructure in mind, and we're encouraged to see that approach recognized through a highly competitive selection process."

The Nordic region is widely recognized as a global leader in district heating innovation, making it an ideal environment for deploying next-generation energy solutions. By combining high-density compute infrastructure with heat recovery at scale, this 8 MW project is expected to provide reliable heating to approximately 2,800 homes, representing a meaningful step toward more sustainable and economically efficient heating systems.
