Visit us at the ISH in Frankfurt am Main from 17 to 21 March 2025! At the world’s leading trade fair for HVAC over 2,000 exhibitors from 55 countries have signed up to present future-oriented solutions in the HVAC sector. 

We will be presenting our user-friendly design software for heat pump and solar thermal systems at our booth A23 in hall 8.

GeoT*SOL is the professional software for planning and designing heat pump systems, both in existing and new buildings. The program allows you to choose from various heat sources, operating modes, and system configurations for each location. A standout feature is the ability to integrate photovoltaic and solar thermal systems. Based on a dynamic minute simulation, electricity consumption, seasonal performance factors and operating costs can be calculated, taking into account blocking periods and tariffs. Selected results can easily be included in the project report for the client.

T*SOL is a dynamic simulation program for designing and calculating solar thermal systems. With T*SOL, systems can be optimally designed, collector arrays and storage tanks dimensioned, and the economic efficiency calculated. T*SOL offers over 200 pre-configured systems and extensive design aids. After the simulation, you receive a comprehensive project report with all system data and detailed simulation and economic efficiency results.

Our expert team will be available on all days of the trade fair to provide product advice and practical insights into the design process. Exclusively for ISH 2025, we are offering all trade fair visitors a special discount on one-year licenses and 3-month licenses for GeoT*SOL, T*SOL, PV*SOL and PV*SOL premium.

We look forward to your visit!
