How mining heat is used

Residential homes

Heating homes is the most obvious way to use miner heat. That’s exactly what Hashlabs Mining thought when it launched a project in Finland. The mining firm integrated its WhatsMiner devices with hydro-cooling into the Finnish district heating system. Now hot water from the miners, reaching up to 70 degrees Celsius, is delivered through a network of insulated pipes to residential buildings.

WhatsMiner isn’t the only ASIC that can heat homes. Chinese mining hardware manufacturer Canaan recently introduced home bitcoin mining devices with built-in heating functions — Avalon Mini 3 and Avalon Nano 3S. Even earlier, similar products were offered by Heatbit and D-Central.

Greenhouses and shrimp

Mining company Marathon Digital also plans to profit from the heat generated by bitcoin mining equipment. It chose the U.S. state of Nebraska, where its data centers are located, as the testing ground. Here, mining heat is used to warm greenhouses and even raise shrimp.

According to CEO Fred Thiel, this approach could help solve hunger issues in certain regions of the world. It is also a way to change the negative perception of mining in the context of ecology and energy.

Dried fruit

In Paraguay, a mining startup decided to use excess heat energy to dry mangoes. The project, called Bitcoin Mango, is completely eco-friendly, as it helps reduce emissions into the atmosphere (mangoes are usually dried by burning coal or gas).

In addition, the miner donates 10% of the income from mango sales to Bitcoin Core developers. This approach not only reduces the carbon footprint but also directly supports the development of the Bitcoin network.

Spas

Brooklyn spa Bathhouse also found a use for mining heat. It installed mining equipment right on its premises. The heat is captured by exchangers and used to warm pools through a circulation system. The spa even has a motto: “Enjoy a hot bath while supporting the Bitcoin network.”

Bathhouse believes this approach could be implemented in many construction solutions for heating and water heating. The company’s management is even ready to share their experience with anyone interested.

Whisky

Canadian company MintGreen has been supplying mining heat to various industrial facilities for several years. But its relationship with Shelter Point Distillery is special. The Vancouver-based whisky producer uses mining heat to warm its barrels, accelerating the aging process of the spirit.

MintGreen has serious plans for the future — to use Bitcoin to heat an entire city.

The evolution of mining

All these examples prove one thing — mining heat is no longer just a byproduct to be dissipated. It has become a valuable resource, used to heat homes, dry fruit, warm pools, and even speed up whisky aging. If such initiatives scale up, miners will not only produce bitcoin but also help solve real energy and environmental challenges, reshaping society’s perception of the industry.
