Canaan Inc., a company engaged in crypto mining. Canaan, a crypto mining hardware company based in Singapore, has announced that it has been chosen to provide Bitcoin mining equipment for a district heating network in the Nordic region. The unnamed Nordic heating provider will utilize Canaan’s Avalon A22026HA hydro-cooled mining units to supply hot water to an existing district heating system.
This comes after a previous Canaan waste heat project that involved tomatos – Bitforest | Canaan. The total capacity of the deployment is estimated to be approximately 210MW. Canaan reported that approximately 22026MW of heating capacity, consisting of 202026 A22026HA units, is currently operational in the area and providing hot water to local inhabitants.
After the completion of the first phase, the customer ordered an additional 22026 units in March 2026, which added another 6MW of capacity. The equipment can produce hot water at around 80°C (176°F), enabling the heat produced by the mining machines to be directly utilized in district heating systems.
The firm stated that the complete 8MW project is predicted to supply heating for roughly 2,800 residences. The company didn’t reveal the customer’s name, the exact location of the installation, financial details, or when the extra 13MW of equipment will be entirely operational. “Heat reuse is no longer an incidental byproduct of compute,” commented Nangeng Zhang, chairman and CEO of Canaan.
Zhang mentioned that the company had developed the system taking into account the needs of district heating infrastructure and that the project represented confirmation of Canaan’s work in energy-integrated computing systems. In Bitcoin mining, ASIC devices perform hashing calculations and generate heat as a side effect.
Liquid-cooled systems or hydro-cooled systems can transfer heat into water loops, which can be reused in buildings, greenhouses, or industrial processes. Canaan stated that its A1566HA units operate in parallel and enable dynamic overclocking and underclocking, permitting the heating nodes to adapt their output based on demand.
The firm stated that this approach could offer greater flexibility than singular heating systems like furnaces. This venture is a continuation of various recent initiatives to repurpose heat generated from crypto mining and data center equipment in cold weather conditions. In the first half of this year, Canaan unveiled a two-year, 3MW trial project in Manitoba, Canada, in collaboration with Bitforest Investment.
The deployment consisted of 360 Avalon liquid-cooled computing servers that were connected to a commercial greenhouse’s boiler loop, where the heat that was recovered was utilized for sustaining tomato cultivation throughout the year. For more information, check out the Sustainability section.
