Overview
Heating costs continue to rise, while certain industrial processes generate large amounts of heat that are usually dispersed and lost. Bitcoin mining is one of them. For AquaTherma, this represented an opportunity to rethink how that excess heat could be put to practical use.
We developed a heat recovery solution that integrates Bitcoin mining with existing heating infrastructure, reusing otherwise wasted energy to support everyday heating needs. The result is a system that lowers operating costs, improves overall efficiency, and moves toward a more sustainable energy setup.
Solution
The system is designed to work alongside any conventional heating plant, such as gas boilers or heat pumps from any manufacturer, enhancing its performance rather than replacing it. Heat produced by ASIC miners is captured and redirected to the heating system to:
-
Maintain stable temperatures during low-demand periods, reducing heat loss and inefficient on-off cycles
-
Preheat incoming cold water, allowing the main heating plant to operate with significantly lower energy input
The system runs fully automatically. Temperature sensors continuously monitor the installation and a local controller adjusts everything in real time. A custom web dashboard lets users check system status, set target temperatures, and fine-tune behavior. After the initial setup, the system takes care of itself.
