The Birth of an Idea

Obwexer’s idea took root when he noticed the computers used for Bitcoin mining generated massive amounts of heat. The intense heat not only warmed his living space but also spurred the notion of utilizing this energy to replace traditional heating. Initially, the mining operation turned his home into a makeshift furnace, significantly reducing his reliance on traditional heating methods. After to thoughtfully weighing the pros and cons, Obwexer concluded, “This form of heating was 4,000 euros cheaper than the previous oil heating, ” he said.

Noise Reduction and Profitability

Initially, the noise from the Bitcoin mining equipment—comparable to the roar of a motorcycle—was a significant drawback. However, the development team successfully reduced it to the hum of a refrigerator. The company founder had this to say, *

“We did it very well.” remarking how his company has improved the devices irreversibly.

Heating with Bitcoin mining is more cost-effective and sustainable than traditional methods. Although electric heating is generally more expensive, the additional revenue from the mining activity can offset these costs. Obwexer explained, ”Heating with electricity is usually more expensive, but with the miner, you make 40 trillion calculations per second and get money back.

“Then, in most cases, it is the cheapest and most sustainable heating method,”

Cost-Effectiveness and Investment

The profitability of Bitcoin heating also hinges on the fluctuating prices of electricity and Bitcoin. For maximum benefit, many users opt to integrate their expensive heating solutions with solar panels.

Using self-generated electricity from a photovoltaic system can significantly reduce costs, though it’s not guaranteed. “It’s also quite possible that the electricity price is significantly higher than the possible proceeds from Bitcoin,” acknowledges Obwexer.

The Company’s Growth and Market Presence

Founded just two years ago, 21energy quickly ascended to the top of the market, recording annual sales in the millions. In 2023, the company posted sales of $2 million, expanded to employ 16 people, and sell their innovative heating solutions in place across 35 countries, including the EU, Switzerland, and Norway.

Product Safety and Comfort

The Bitcoin heaters, easy to install and requiring only a standard electric socket and a WLAN connection, are designed with safety and comfort in mind. They feature a surface temperature between 40 to 50 degrees Celsius, ensuring they are safe for both children and pets. In an open quote Obwexer confidently stated, “No toddler can burn.” And we regularly get photos
of their cats from our customers who have made themselves comfortable in the heating.

Market Dominance and Future Innovations

With its current global leadership position, 21energy is prepared for potential competitors. As Obwexer notes,
There are only two or three other companies worldwide, and we are currently simply at the forefront. But of course, there will be more competitors in the future if our thesis is correct that this will be one of the main heating methods in decades.
Obwexer hints at upcoming innovations, including a flat wall module that will be both quieter and more powerful.

The journey of 21energy underscores how innovative thinking can transform everyday necessities like home heating into opportunities for economic and environmental sustainability. By merging cryptocurrency mining with heating, the company has opened a path to a greener future.
