Around 20 flats in a building on rue Beaubourg in the 4th arrondissement have seen their heating bills drop by about €70 a year after a heat pump was installed to capture and filter hot air generated by trains on the underground network.

The scheme is being rolled out to other buildings along the Metro’s Ligne 11.
