Efficient heat pump design with GeoT*SOL
Are you looking for a professional and user-friendly software for the planning and design of heat pump systems? Then GeoT*SOL is the ideal tool for you.
GeoT*SOL offers you the choice between different heat sources (soil, air and groundwater), operating modes (monovalent, monoenergetic and bivalent) and numerous system configurations for your location. The program allows for bivalent systems with boiler as heat generator as well as the integration of solar thermal systems and photovoltaic systems.
Based on a dynamic minute simulation, electricity consumption, seasonal performance factors, operating costs and other system data can be calculated, taking into account blocking periods and tariffs. With these parameters, GeoT*SOL helps you to develop efficient and economical heat pump systems. Selected results can be conveniently incorporated into the project report for the client.
Product highlights
Heat pump simulation with precise forecasts, integration of further heat generators and PV system
With GeoT*SOL you can simulate the heat pump system to the minute in order to determine seasonal performance factors (SPFs) and contribution margins. Monovalent, monoenergetic and bivalent modes of operation are available for selection. Other heat generators such as gas condensing boilers and solar thermal systems can be added. The integration of a photovoltaic system is also possible.
The seasonal performance factor according to VDI 4650 is an important parameter for comparing systems according to their efficiency. It forms the basis for many funding measures and approval procedures.
Databases with heat pumps, collectors, boilers and storage tanks
GeoT*SOL is delivered with an extensive database. This contains more than
- 4,000 collectors (flat plate collectors, tube collectors, air collectors)
- 5,000 boilers (condensing boilers, wood boilers, pellet boilers, etc.)
- 4,000 heat pumps (brine/water, air/water, water/water)
- 600 storage tanks (combination and buffer storage, monovalent, bivalent, etc.)
In addition, manufacturers can have additional storage tanks, boilers, collectors and heat pumps added free of charge. Contact: database@valentin-software.com
Dynamic, configurable diagrams
The simulation of the heat pump and PV system provides dozens of simulation results (data series) on an hourly basis. In GeoT*SOL, these can be displayed and evaluated as dynamic, configurable diagrams.
The diagrams can be configured extensively: from the display range (1 day to 1 year) and the resolution (hours to months) of the diagram, to the color and shape (bars, lines, points) of the individual data series. Selected diagrams can be conveniently incorporated into the project report for the client.
More product features
Global climate data available
GeoT*SOL provides you with the latest TMY data of the DWD (current state 2017, averaging period 1995-2012) for Germany and more than 8,000 further climate locations for the whole world based on Meteonorm 8.1. You can use the interactive map to conveniently select the climate data. Locations not included are interpolated using satellite data and neighboring ground measuring stations. The import of your own measurement data takes place via files in DWD, Meteonorm or WBV format.
Tariffs and blocking periods
Up to three blocking times can be set using the usual rules (intervals and limited duration) in order to be able to precisely depict the supply situation. Furthermore, the electricity price for the heat pump can be divided into high tariff (HT) and low tariff (NT).
Profitability analysis
GeoT*SOL calculates the profitability according to the recommendation of the German Solar Association (BSW), taking subsidies into account: Cost comparison of the heat pump system with a reference system; Capital value and production costs (heat price); Modified internal rate of return (MIRR); Profit under consideration of reinvestment.
Configurable project report
Help clients and partners understand the specifics of their heat pump system with appealing reports. The content can range from a short report with seasonal performance factors to a detailed project report with diagrams and system components.

Release notes
The following new features and changes are included:
- The geothermal plant systems can now also be simulated with photovoltaics to determine how much PV energy can be used to cover the electrical loads (heat pump, heating rod, source-side pumps and solar circuit pump).
- Optimization of PV energy self-consumption by optionally increasing and/or decreasing the storage temperature.
- Creation of user-defined diagrams in different temporal resolutions. Up to eight data series can be selected in one diagram.
- The user-defined diagrams can be integrated into the project report.
- New online help
The following bugs have been fixed:
- In some cases energy was supplied by the heating rod although it was not needed.
- Circulation losses were no longer visible after reloading a project.
- Access violation when loading old projects with storage tank.
- The heating rod power of the heat pump was sometimes not automatically adopted on the Mode of Operation page.
The following bugs have been fixed:
- In some storage tanks, sensor heights were incorrect, so that they were not loaded (systems with buffer tanks for heating like HPS 7).
- In standard storage tanks, the heat exchanger was not scaled when the volume was changed.
- In the system HPS 8, the boiler delivered an incorrect supply temperature, so that the system ran in continuous DHW operation and the heating system was undersupplied.
The following new features and changes are included:
- Update of the heat pump and storage database.
- New climate data:
- Meteonorm 8.1
- PVGIS
- Solcast
The following bugs have been fixed:
- Error when updating the database.
- In some storage tanks the collector connection height was wrong.
- When using large heating buffer tanks, the hot water tank was not loaded correctly in system WPA 8.
- In the evaluation of the heat pump according to the GEG, the annual performance factor was incorrectly used as a criterion.
- Due to the mode of operation, the boiler in system WPA 7 did not run in summer.
The following new features and changes are included:
- Longer pre-processing of the heat pump in parallel operation. As a result, the boiler starts later and the fraction of the heat pump in the generated energy is larger.
- The window size of the program can be adjusted as desired. At the next start the program will be started with the last used dimensions.
- The system selection page was updated (filter).
- The database now includes over 600 tanks from well known manufactures. Tanks can now be configured or be selected from the database.
- Display of the "Solar Keymark" certification for collectors.
- Updated climate data based on Meteonorm 7.3.
The following bugs have been fixed:
- The network license cannot be registered again.
The following new features and changes are included:
- Calculation of heat pump performance factor updated due to new calculation guidelines (VDI guideline 4650, sheet 1, March 2019).
- New bivalent heat pump system (HPS 8) with hydraulic switch and separate buffer tanks for space heating and domestic hot water.
- Updated database with over 3,900 heat pumps (as of January 2020).
The following bugs have been fixed:
- Incorrect simulation results when simulating systems with geothermal collectors.
