Summary
Heat pumps are energy-efficient techniques for heating buildings and their use has been increasing for years. A greater variety of possible heat sources and suitable heat exchangers are also developing. Among the possible heat sources and systems are:
-air-to-water heat pumps,
- geothermal probes,
- groundwater wells,
- geothermal heat collectors,
- energy piles,
- geothermal baskets,
- ice storage,
- air absorber and
- heat exchangers for waste water and running water.
The Excel-based information tool developed in the project is available online and contains plant data, literature and market research. This is to provide an overview of cost-benefit efficiency, general conditions, space requirements, investment and operating costs and construction and installation effort. In addition, suitable heat sources are to be identified for specific buildings with defined heating and cooling requirements.
For the online tool, thirteen different buildings and their installation technology were evaluated and a comprehensive simulation study was carried out.
The tool is available here for free (only available in German language).
