A Stockholm data center's heat exchangers are being linked up to the city's heating network.
Nordic data-center operator Digiplex and Stockholm Exergi, the Swedish capital's leading energy supplier, are going to be using excess heat from servers to warm the equivalent of 10,000 households.
The two companies say their large-scale heat reuse agreement is the world's first where an operational data center with indirect evaporative air-to-air heat exchangers is being retrofitted to transfer excess heat to a city's district heating grid.
