New: Free heat pump calculator


With our new heat pump calculator GeoT*SOL online at you can now easily simulate your heat pump system.

For the calculation, GeoT*SOL online only requires a few details about the location, system type and heat demand. When selecting the heat pump, tanks, boilers and collectors, you can choose your manufacturer and specific product from an extensive database. In the last step, the annual simulation is carried out based on current climate data. The result shows the seasonal performance factor (SPF) of the heat pump and, in a graphical representation, the energy produced by each component.

Are you looking for a simulation with more options such as profitability analysis, configurable diagrams, a photovoltaic system and a detailed project report? Try the 30-day trial version of GeoT*SOL, our planning and simulation software for heat pump systems.
