Description & Project Overview

Description of services - subject of procurement workshop planning, delivery, assembly, installation for the complete hydraulic integration including heat pumps and the complete integration point. In addition to the delivery and installation of the complete heating system, the contractor supports and coordinates the installation of the system and accompanies the commissioning. Text, what does the entrepreneur have to bring? Project description The plan is to dismantle the existing fossil energy generators at the Riedhofstrasse 62 property in order to replace them with two air-water heat pumps. The proposed solution envisages designing the heat pumps in such a way that the entire energy requirement can be covered by renewable sources in the future. The existing heating center at Riedhofstrasse 62 will remain as a distribution center. For reasons of space, the current tank room on the first basement floor of Riedhofstrasse 62 will be used for energy generation. The converter station and the energy storage are to be installed in this newly created technical room. The other two tank systems will be shut down in a second step. The existing exhaust systems will be taken out of operation and professionally sealed to avoid possible structural damage. However, it remains in place so that it can be used as a climbing zone in the future, for example. In the existing heating circuit distributor in the central office, only the pumps and the valves are replaced.
