Case Study – Neue Heimat Tirol | Student Housing with Shower Heat Recovery in Innsbruck, Austria
One of Austria’s most advanced student housing projects integrates 40 Recoup ShowerPipes to recover shower wastewater heat and reduce domestic hot water energy demand
Project Details
Project type: Residential project for young people and students.
Project location: Innsbruck – Austria
Completion: 2026
Product: 40 VX 2100 showerpipes
Partner: Robin Heat
Project Back ground
As part of this new residential development in Innsbruck, Recoup ShowerPipe systems have been integrated to recover heat from shower wastewater. The solution is expected to significantly reduce domestic hot water energy demand while improving the overall energy performance of the building.
Key Results
>50% | 20-25% | 40 |
System Concept
The system is based on a decentralized wastewater heat recovery solution integrated into a high-efficiency domestic hot water installation. Wastewater heat is recovered directly from the showers and reused to improve overall system efficiency.
Hydraulic Concept (Scheme A)
- Preheating of the cold-water supply to the thermostatic mixing valve and the
freshwaterstation.
- Highly efficient overall system configuration.
Project Status & Monitoring
Following completion, detailed performance monitoring will be carried out in cooperation with the Passive House Institute and the University of Innsbruck to validate system efficiency, energy savings, and long-term operational performance.
Expected Performance
- More than 50% heat savings during shower operation.
- Approximately 22–25% reduction in total energy demand for domestic hot water preparation, including additional hot water consumers and system-related losses (e.g. circulation losses).
Funding
The project has been submitted under the Tyrol State Housing Subsidy Program (Wohnbauförderung Tirol).
