Canaan to supply 8 MW hydro-cooled miners to heat 2,800 homes

Canaan Inc. will install 920 hydro-cooled Avalon A1566HA mining units to provide about 8 megawatts of hot water to a Nordic district heating network that serves roughly 2,800 homes. The units are designed to feed high-temperature water directly into the existing municipal system.

An initial 2 MW phase of 228 A1566HA machines is already in operation 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 692 units, adding about 6 MW and bringing the total to roughly 8 MW at full capacity. The project replaces previously used fossil fuel-based heat in the portion of the network served.

The A1566HA units use liquid cooling and are designed to produce water temperatures near 80 degrees Celsius, matching common district heating requirements in the region. Canaan describes the system as a parallel architecture in which multiple miners operate together as a single heating node with support for dynamic overclocking and underclocking. That design spreads thermal generation across many machines, which the company says delivers steadier output than single-source boilers and lowers interruption risk.

In a company release, Nangeng Zhang, Canaan’s chief executive, wrote: ‘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.’

Nordic countries have extensive district heating networks and regulatory frameworks that support integrated thermal solutions. Project developers and utilities in the region have pursued ways to convert waste heat from computing equipment into usable district energy, and regulators in some countries have encouraged such initiatives.

Canaan, which trades on Nasdaq under the ticker CAN, framed the contract as part of its effort to provide computing equipment that can deliver usable thermal output. The deployment is an example of bitcoin mining infrastructure used to produce both computing power and district-scale heat for residential customers.
