Geothermal Training System

The Festo Geothermal Training System (46126) is a compact workstation to teach the fundamentals of residential geothermal heat pumps. This system allows students to develop knowledge in heat transfer and air conditioning. The exercises are designed learn the skills required during installation, operation, and troubleshooting of geothermal heat pumps.

From Our Partners at


Geothermal heat pumps are among the most energy efficient systems available today for heating and cooling residences. Like solar and wind energies, geothermal is among the renewable energy sources whose utilization increases each year, meaning that more qualified technicians need to be trained.

The Geothermal Learning System is designed to maximize learning capabilities by regrouping every subsystem in geothermal home energy installations. It consists of a geothermal heat pump, ground-loop heat exchanger, pumping station, domestic hot water system, circulation pump, control panel, and the instrumentation required to measure the operating parameters of the system.

Students learn the fundamentals of heat transfer, refrigeration, and air conditioning applied to geothermal heat pumps. It is suitable for varied educational requirements: future system designers and builders, maintenance technicians, and students learning the concept of energy efficiency in general.

With its courseware containing detailed theory and practical exercises, the Geothermal Learning System is the most efficient and effective way to gain the knowledge and skills that are put into practice every day in the geothermal industry.

Features & Benefits
