Points of Focus

• A Manitoba pilot tests whether Bitcoin mining heat can replace part of greenhouse heating demand.
• Liquid-cooled mining systems aim to capture most of the energy normally lost as heat.
• The project probes if mining infrastructure can fit cold-climate agriculture at scale.

A Bitcoin mining project in central Canada is testing a simple idea with practical stakes. Instead of venting heat into the air, mining equipment is being used to warm commercial greenhouses through winter. The trial puts numbers behind a claim long made by the industry: that mining’s byproduct heat can serve real-world uses beyond hashing.

The 3-megawatt pilot is running in Manitoba through a partnership between Canaan and Bitforest Investment, according to a company announcement released on January 6, 2026. It is designed as a proof-of-concept, not a marketing demo, with performance tracked over a planned 24-month period.

Bitcoin mining heat reuse in Manitoba greenhouses

The setup routes heat from liquid-cooled Bitcoin mining servers into a closed-loop system that preheats water feeding the greenhouse boilers. This reduces how much additional energy is needed to maintain growing temperatures during harsh winters in Manitoba.

Canaan says the system uses hundreds of liquid-cooled machines housed in containerized modules. Liquid cooling matters here. It allows the operation to produce consistently hot water, rather than low-grade warm air, making the heat usable for agriculture instead of a marginal add-on.

Measuring economics, not just sustainability claims

What separates this project from earlier experiments is how tightly it tracks cost and uptime. The target is near-continuous operation, with heat capture expected to cover most of the electricity consumed by the mining equipment. If those assumptions hold, the greenhouse can reduce reliance on fossil-fuel boilers without installing a separate heating system. According to project estimates, most of the electricity consumed by the mining servers is expected to be recoverable as usable heat under normal operating conditions. From a capital standpoint, the design also removes the need for large industrial cooling towers often required in liquid-cooled data centers. That changes the cost profile. Instead of paying to dump heat, the operator treats it as a secondary output.

The companies involved frame the project as data-driven. Performance metrics such as heat recovery rates, system stability, and maintenance load are being logged to assess whether this model works beyond a single site.The pilot also lands amid growing research challenging common assumptions about how Bitcoin mining interacts with energy systems.

Why cold-climate agriculture is the real test

Greenhouses in Canada face a clear constraint. Heating is a fixed cost, not a seasonal choice. By tying compute infrastructure directly into existing boiler loops, this pilot tests whether Bitcoin mining can integrate into agricultural energy systems rather than sit alongside them.

Bitforest’s Manitoba operations focus on year-round tomato production, where temperature swings directly affect yields. That makes the site a useful stress test. If the system underperforms, the impact shows quickly.

The outcome will matter beyond one province. If mining heat can offset fuel use in agriculture without adding operational risk, it reshapes how energy-intensive computing fits into cold regions. This project is small by grid standards. Its implications are not.
