Anergy grid /­ seasonal underground storage, Skating Rink – KEK, 8700 Küsnacht/­ZH

description:

‎
A new anergy grid has been built in the Zurich lakeside municipality, which uses the surplus waste heat from the staking rink via a seasonal underground storage. Synergies with surrounding buildings with a demand for heat were utilised.The waste heat generated during ice production is fed into the geothermal probe field and temporarily stored in the ground. As soon as the properties in the vicinity require heat energy, the heat can be extracted from the ground and transported to the customers via a heat network. 50 GEROtherm^® FLUX de 43 mm geothermal probes, each 310 metres long, were sunk into the ground
