You can choose from different heat sources and system configurations for your location.

A key feature is the integration of solar thermal systems for domestic hot water or space heating. The requirements, losses and consumption are determined as a result of the dynamic simulation of minutes. These form the basis on which electricity consumption, annual performance ratio and costs are calculated, taking into account periods out of service and tariffs. With these parameters, GeoT*SOL® evaluates the efficiency of the system.

Price and heat performance are given for the heat pump and a comparison system.

Databases with heat pumps, collectors, boilers and storage tanks

GeoT*SOL is delivered with an extensive database. This contains more than

  • 4,000 collectors (flat plate collectors, tube collectors, air collectors)

  • 5,000 boilers (condensing boilers, wood boilers, pellet boilers, etc.)

  • 4,000 heat pumps (brine/water, air/water, water/water)

  • 600 storage tanks (combination and buffer storage, monovalent, bivalent, etc.)
