An apartment building in Vienna was successfully converted from a gas heating system to an iDM heat pump.
The heating system in an existing apartment building near Vienna’s Westbahnhof station was successfully converted from gas to a sustainable heat pump solution. The building comprises 12 old apartments and 3 attic apartments with a total usable living space of 970 m².
Refurbishment and modernization: As part of the refurbishment, some of the apartments were equipped with modern underfloor heating and fan coils to ensure maximum comfort. The apartments that have not yet been refurbished will continue to be heated by conventional radiators, but there are plans to gradually convert these to underfloor heating as well.
Innovative drilling solution in the inner courtyard and sidewalk: The limited space for the deep drillings in the inner courtyard posed a particular challenge. Of the seven deep boreholes required, only four could be accommodated on the grounds of the building. Thanks to an innovative solution and a new approval process by the City of Vienna, the remaining deep boreholes were placed under the sidewalk in the public space to ensure the full heating capacity of the heat pump.
Additional advantages: In addition to the heating function, the system can also be used to cool the building. Furthermore, an installed photovoltaic system contributes to the sustainable energy supply of the building and enables a particularly environmentally friendly use of resources.
This retrofit impressively demonstrates how iDM heat pump technology paves the way to a sustainable future while offering maximum comfort – another example of our pioneering work in the use of renewable energy sources.
