Valentin Software GeoT*SOL 2021 R1

The software developer Valentin Software GmbH announced the launch of GeoT*SOL 2021 R1 is a dynamic simulation program for professional planning, calculation and design of geothermal solar systems.

New Features

Evidence for Germany’s Building Energy Act (GEG)
The new Building Energy Act (GEG), which includes the EnEV and EEWärmeG, has been in force since November 1, 2020. GeoT*SOL has been adapted so that the degree of fulfillment of the heat pump and solar system will continue to be calculated and included in the project report. In bivalent systems, boilers that use biomass are also taken into account.
Storage tanks can be selected from the database
The extensive and revised T*SOL storage tank database is now available in GeoT*SOL. There are currently over 600 products from leading manufacturers to choose from. Standard storage tanks can of course be used for your own optimization and calculations, the volume and heat losses of which can be edited. As with heat pumps, collectors and boilers, certain storage tanks can also be marked as favorites and can therefore be selected quickly and easily.
Program interface
The window size of the program can be adjusted as required. The dimensions last used will be restored at the next start. In addition, the filter for the system selection has been simplified.
Climate data
Update of the climate data based on test reference data sets of the DWD for Germany and Meteonorm 7.3 worldwide.
Optimization of heat pumps
In the simulation in parallel operation mode, the heat pumps cover a larger proportion of the heat generation than in earlier program versions. This is due to the operation that has been extended for the heat pumps and means that the boiler starts up later.


Are you looking for a user-friendly special tool for the planning and design of heat pump systems? Then our GeoT*SOL program is the perfect project partner for your design work.

You can choose between different heat sources (soil, air and groundwater) and modes of operation (monovalent, monoenergetic and bivalent) for your location. The integration of solar thermal systems and bivalent systems with boiler as heat generators should be emphasized. Requirements, losses and consumption are determined as a result of a dynamic minute simulation. Based on this, electricity consumption, seasonal heat performance factor and costs are calculated taking into account off-periods and tariffs. With these parameters, GeoT*SOL evaluates the economic efficiency of the system. The heat price and return are shown for the heat pump system and a comparison system.

GeoT*SOL 2021 has been expanded to include a storage tank database with over 600 products from leading manufacturers. This means that storage tanks from different manufacturers can be simulated and compared.

The systems were optimized for the heat pump in parallel operation mode. This means that the heat pumps can cover a larger proportion of the heat generation.

The program interface is now even more user-friendly. The window size can be adjusted as required and the settings are restored the next time the program is started.

Valentin Software develops modern software solutions for design, dynamic simulation and yield calculation. We offer a range of design tools for photovoltaic (PV*SOL), solar thermal (T*SOL) and heat pump (GeoT*SOL) systems.
