Valentin Software GeoTSOL 2026 R2

Are you looking for a user-friendly special tool for the planning and design of heat pump systems? Then our GeoT*SOL program is the perfect project partner for your design work.

You can choose between different heat sources (soil, air and groundwater) and modes of operation (monovalent, monoenergetic and bivalent) for your location. The integration of solar thermal systems and bivalent systems with boiler as heat generators should be emphasized. Requirements, losses and consumption are determined as a result of a dynamic minute simulation. Based on this, electricity consumption, seasonal heat performance factor and costs are calculated taking into account off-periods and tariffs. With these parameters, GeoT*SOL evaluates the economic efficiency of the system. The heat price and return are shown for the heat pump system and a comparison system.

Simulation of the contribution margin of the heat pump and other heat generators
With GeoT*SOL you can simulate the heat pump system to the minute in order to determine annual performance figures (COP) and contribution margins. The systems can have other heat generators such as gas condensing boilers and solar systems. Movovalent, monoenergetic and bivalent modes of operation can be selected for operation.
Determination of the annual performance factor according to VDI 4650

The annual performance factor according to VDI 4650 is an important factor for comparing plants according to their efficiency. It forms the basis for many funding measures and approval procedures.
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.)

In addition, manufacturers can have additional storage tanks, boilers, collectors and heat pumps added free of charge
