Sump water heating for in-house use

Utilising direct heat from sump water

Forum :terra nova

  • Forum :terra nova, on the northern edge of the Hambach open-cast mine, is a tourist attraction, restaurant and exhibition venue, and is unusual and innovative at both an architectural and a technical level.
  • Heat recovery uses sump water from the Hambach open-cast mine for air-conditioning and heating, while electricity is supplied from its semi-transparent solar roof. 

Elsdorf pump workshop

  • The workshop near Elsdorf maintains and repairs 1,600 pumps a year using the latest technology, including a 37-metre-deep test reservoir.
  • The building’s energy system is also state-of-the-art: About 7,000 square metres of hall space and 1,200 square metres of office and social areas were fitted with underfloor heating capable of accommodating heavy goods vehicles and operated using sump water. It has been shown that the heat exchangers are enough even in periods of frost, which means the heat pumps are rarely used.
