21ENERGY Logo grün transparent Sustainable Heating Solutions

We are just getting started...

In September, the presentation of the 21ENERGY Bitcoin Heater took shape at the BTC22 conference in Innsbruck.

Since then, we have been working at full speed on the development of the product according to the motto ‘move fast and break things’.
This webshop was also built according to this motto and is constantly being refined.

Heizen mit Bitcoin Mining... in Europa? Ist das möglich?!?
