Canaan just landed a contract that makes Bitcoin mining sound almost… wholesome. The ASIC manufacturer won a competitive bid to supply hash-to-heat equipment for an 8 MW district heating project in the Nordic region, partnering with an unnamed local heating provider to turn mining waste heat into something that keeps families warm during Scandinavian winters.
The company will deploy its Avalon A1566HA hydro-cooled mining units to capture waste heat and generate hot water at approximately 80 degrees Celsius, hot enough to integrate directly into district heating networks. The project is expected to provide heating services to around 2,800 homes.
From proof of concept to full-scale deployment
This isn’t a cold start. An initial 2 MW phase is already operational, running 228 of Canaan’s hydro-cooled units. A follow-on order for 692 additional units was placed back in March 2026, bringing the total deployment to 920 units across roughly 8 MW of thermal capacity.
Bitcoin mining hardware converts electricity into two things: hash power and heat. Traditionally, the heat is the unwanted byproduct, vented into the atmosphere. Hydro-cooled systems like Canaan’s Avalon A1566HA capture that thermal energy through liquid cooling loops, routing it into something useful instead of wasting it. In this case, that means hot water for district heating — the same kilowatt-hour does double duty, which changes the economics and the environmental calculus considerably.
