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

Canaan Deploys 920 Avalon A1566HA Miners to Heat 2,800 Homes in Nordic District Network

The project uses Canaan‘s (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.

Canaan’s CEO Nangeng Zhang said he was personally involved in designing the system’s form factor and led its thermal and deployment optimization. “Heat reuse is no longer an ancillary byproduct of compute,” Zhang remarked in the release. “It is central to building a more efficient, sustainable energy future, and a core part of how we think about system design at Canaan.”

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.

The Nordic region has long led Europe in district heating adoption, where centralized hot water networks serve large portions of urban and rural populations. Governments there regularly incentivize district heating projects because they distribute thermal energy efficiently across wide areas.

Delivering usable high-temperature heat at scale has been a persistent technical problem in the hash-to-heat space. Most compute waste heat tops out at temperatures too low for direct integration into district systems. In the release, Canaan stated that its semiconductor and system design technology addresses that gap, producing output at temperatures that meet district heating standards.

Canaan views the competitive selection as a broader validation of its push into energy-integrated compute infrastructure. The company framed the win as evidence that hash-to-heat solutions are positioned to displace aging fossil fuel-based heating systems, particularly in regions with favorable regulatory conditions.

The Nordic hash-to-heat project marks one of the more concrete examples of bitcoin mining infrastructure being deployed for dual-purpose use, producing both compute output and district-scale thermal energy for residential customers.
