Stimergy recycles heat from data centers

The digital boiler produced by this young French company recovers heat from data centers to supply buildings with hot water.


Data flows continue to increase, and with them, the number of datacenters needed to store, process, and share them. Unfortunately, datacenters are very energy intensive: they consume large amounts of electricity both in operation and to constantly cool the servers which produce large amounts of heat. The upside is that because we need heat all year round – in particular for hot water in residential buildings, businesses and public facilities – it doesn’t have to be lost.

Christophe Perron, founder and president of Stimergy took the issue on board and devised a solution that enables builders and building operators to reduce their costs and their environmental impact. His idea? A "digital boiler". It’s a datacenter equipped with a system to recover the heat produced by computer servers . 

Installed in the boiler room of any building (residential or offices, student halls of residence, swimming pool, industrial site, etc.), it recovers the heat to produce a hot water supply. According to Stimergy, its digital boiler will cover up to 60% of a building's hot water needs.

The energy is used twice: once by the server farm (which hosts Stimergy customers’ data) and a second time to heat water. And because the heat is recovered, there’s no need to cool the servers -further reducing energy consumption. 

 

Smart city

Digital boilers were installed in a social housing building in Nantes, in a student residence in Grenoble and, in May 2017, in the Butte-aux-Cailles swimming pool in Paris’ 13th arrondissement. Conducted in collaboration with the City of Paris, the Butte-aux-Cailles project is a smart city benchmark project.

Stimergy offers an environmentally friendly, economical solution for hosting digital data that also improves the energy performance of urban infrastructure. This excellent idea has won several awards, including the 2016 Circular Enterprise Trophy.
