Operating principles
Our renewable energy is recovered from our servers working inside our digital boiler. All the calories dissipated by these servers are collected by a coolant oil in which they are immersed. These calories are then carried and stored in a water tank. When a user needs hot water, the pre-heated water is integrated in the water heating and distribution system. These free calories are replacing carboned energy calories.
