Canaan Wins Nordic Heating Bid, Turns Bitcoin Mining Waste Heat Into Residential Hot Water

Canaan Inc. won a bid to deploy 8 MW of hydro-cooled Avalon A1566HA units to a Nordic district heating network. The system is expected to heat about 2,800 homes by producing high-grade hot water near 80°C and feeding it directly into existing district heating infrastructure. A 2 MW phase is already operating with 228 units supplying local residents. After performance, a follow-on order in March 2026 adds 6 MW and 692 more units, bringing total capacity to 8 MW. The parallel architecture uses multiple miners per heating node with dynamic overclocking and underclocking to deliver consistent output, simplify maintenance, and reduce supply interruption risk.

"Canaan Inc. won a competitive bid to deploy 8 MW of Avalon A1566HA units to a Nordic district heating network. The 8 MW project is expected to heat approximately 2,800 homes, replacing legacy fossil fuel-based heating systems. Canaan placed a 6 MW follow-on order in March 2026, signaling customer confidence and expansion potential."

"The project uses Canaans (Nasdaq: CAN) hydro-cooled Avalon A1566HA series units, which produce high-grade hot water at temperatures near 80 degrees Celsius. That heat feeds directly into the customer's existing district heating infrastructure, replacing traditional heating solutions the provider had previously relied on. The total deployment spans approximately 8 MW of capacity."

"An initial 2 MW phase, comprising 228 A1566HA units, is already operating in the region and supplying hot water to local residents. Following that performance, the unnamed Nordic heating provider placed a follow-on order in March 2026 for an additional 6 MW, adding 692 units to the network. At full capacity, the 8 MW installation is expected to provide reliable heating to roughly 2,800 homes."

"One technical advantage Canaan highlights is the parallel architecture of the A1566HA units. Because each heating node consists of multiple miners operating side by side with dynamic overclocking and underclocking support, the system delivers more consistent output than single-source heating equipment like boilers. That architecture also simplifies maintenance and reduces the risk of supply interruption."
