Clever heating for Parisian pools

28 February 2017

Paris’ innovation has reached a new level with the introduction of a clever way to heat local swimming pools.

To keep swimming fanatics happy all year round and energy bills low, the city turned to two unconventional energy sources: sewage and computer servers.

Hot flush

Sinks, toilets and washing machines pour waste into the Paris sewage system at a toasty 12 – 20 degrees Celsius. In an effort to capture this natural source of warmth, metal plates are installed on the pipes that run under the local pool. A heat-pump system then transfers the warm water directly into the pool (filtered and cleaned, of course!).

Data furnace

With our online world ever expanding, computer servers are built with a lot more grunt and cost a fortune to keep cool. To harness the excess heat, start-up company, Stimergy, invented a new system called “data furnace”.

Stimergy plans to install hundreds of computer servers in the basement of another local pool. Heat thrown off by the servers will be channelled to the boiler, which in turn heats the water for the pool and showers.

Paris’ deputy manager in charge of sports, Jean-François Martins, said it is all part of a plan to make the Paris’ swimming pools more “eco-responsible” in preparation for the 2024 Olympic Games, which Paris is in the running to host.

“We wish to reduce the environmental impact and ecological footprint of these facilities, while reducing chemical product use,” said Mr Martins.

Next time your computer over-heats or you flush the toilet, think about the innovative ways you could harness the excess heat to make Australia cleaner, greener and more economical.
