The design and simulation software for heat pump systems


Efficient heat pump design with GeoT*SOL

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.

GeoT*SOL is available in English 🇬🇧, French 🇫🇷 and German 🇩🇪. Download your free 30-day trial now!

 

Product highlights

More product features

GeoTSOL_climate data_EN

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 8.2. 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.

GeoTSOL_tariffs offperiods_EN

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).

GeoTSOL_financial analysis_EN

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.

Different project report configurations can be created for different requirements. Changes are immediately displayed in the live preview. The report can be exported as a Word file for further editing or directly as a PDF.

Release notes

May 7th 2024GeoT*SOL 2024 Release 1

The following new features and changes are included:

  • Calculation of the heating load via building type, year of construction and renovation status or via the annual consumption by entering the energy source, heat generator and consumption. The underlying data is based on the IEE project TABULA.
  • Heat pump database based on Keymark test reports and EN 14825. The extensive data covers different climatic conditions and flow temperatures, which enables a more accurate simulation.
  • Boiler control in bivalent systems improved.
  • Updated calculation of the seasonal performance factor (SPF) in accordance with VDI 4650 Sheet 1 from February 2024.
  • Display of full load hours and switch-on processes of the heat pump, these provide indications of oversizing or undersizing of the heat pump.
  • Climate data updated, based on Meteonorm 8.2 (climate data period 2001 - 2020).
  • Adaptation to the GEG (German Buildings Energy Act) of January 1, 2024 and display of the shares of heat generation according to § 71 for heat pumps and solar thermal systems.
  • Adaptation to the EWärmeG (Baden-Württemberg) from February 10, 2023.

The following bugs have been fixed:

  • Incorrect supply and return temperatures of the boiler in the results graphs.
  • Project data of the heat source and the heating element were not loaded.
  • Energy generated by the photovoltaic system was not included in CO2 emissions.
  • Orientation of the collectors in the southern hemisphere was incorrect.
  • Sensor heights of heating buffer tank with heat exchanger corrected.
  • In some cases, the heating element was in operation even though it was not needed.
  • Creation of locations via MeteoSyn sometimes not possible.
  • Selection of the printer sometimes did not work.
July 20th 2023GeoT*SOL 2023 Release 3

The following new features and changes are included:

  • Database updated.

The following bugs have been fixed:

  • The load profile of the electrical consumptions of the heat pump system was partially not exported completely.
  • Download dialog during software update was not visible.
  • Error when exporting the electrical consumption of the heat pump system if the file to be exported to was open in another program.
June 5th 2023GeoT*SOL 2023 Release 2

The following new features and changes are included:

  • Project report:
    • Live preview of the project report.
    • Create your own configurations of the project report.
    • Project report can be exported as a Word file.
  • Photovoltaic simulation results are displayed in more detail.
  • Heat pump simulation model adapted to DIN EN 14825.
  • MeteoSyn:
    • New climate data for Germany (Valentin Software TMY procedure with DWD data as basis, 1995 – 2012).
    • SolarAnywhere as additional climate data provider.
    • Revised Meteosyn interface in the "Generate climate data for new location" dialog.
    • Improvement of the location search in Meteosyn.
    • Check of the MeteoSyn database in four phases:
      • Checking the files and database entries for invalid data or data with reduced quality.
      • Search for duplicates in WBV files.
      • Search for duplicates in database entries.
      • Search for imports and updates.

The following bugs have been fixed:

  • Negative energies in energy generated and power consumption.
  • Negative tank temperatures.
  • Selection of PV consumers was not saved in the project.
  • Folders without data series were visible in the result graphics.
  • Different data series were partially displayed in the same color in the result graphics.

February 6th 2023GeoT*SOL 2023 Release 1

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.
