About GeoTSOL 2026

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.

Inkscape

Inkscape 1.4.4

Inkscape is an open-source vector graphics editor similar to Adobe Illustrator, Corel Draw, Freehand, or Xara X. What sets Inkscape apart is its use of Scalable Vector Graphics (SVG), an open XML-based W3C standard, as the native format. In contrast to raster (bitmap) graphics editors such as Photoshop or Gimp, Inkscape stores its graphics in a vector format. Vector graphics is a resolution-independent description of the actual shapes and objects that you see in the image. A rasterization engine uses this information to determine how to plot each line and curve at any resolution or zoom level. Contrast that to bitmap (raster) graphics which is always bound to a specific resolution and stores an image as a grid of pixels. Inkscape can import and display bitmap images, too. An imported bitmap becomes yet another object in your vector graphics, and you can do with it everything you can do to other kinds of objects (move, transform, clip, etc.) While Inkscape does not have all the features of the leading vector editors, the latest versions provide for a large portion of basic vector graphics editing capabilities. People report successfully using Inkscape in a lot of very different projects (web graphics, technical diagrams, icons, creative art, logos, maps).
