Tender Details

New Rebstockbad building, here: conversion of a research borehole into a geothermal coaxial probe Bäderbetriebe Frankfurt GmbH plans to cover part of the heat requirements for the new building of the Rebstockbad Frankfurt using geothermal energy. There is a multi-layered one for this System planned. A flat 100 m geothermal probe (EWS) array of 16 probes in the northern part of the property was constructed for cooling in the summer months. Furthermore, two 399 m deep probe fields are currently being built, around a third of the to provide annual heat requirements. These are 9 EWS in the north field and 11 further EWS in the south field. Each field is connected to a heat pump to bring the extracted geothermal energy to the required flow temperature level. This The tender deals with the backfilling of the existing, 1, 060 m deep research borehole on the site down to 850 m, and the subsequent conversion to an 850 m deep coaxial probe. The heat gained is then used to regenerate the 399 m deep southern field.
