Introduction
Energy piles are presented as the most efficient and economical way to utilize geothermal energy. They offer low additional costs and are considered the most economical geothermal heat exchangers.

Advantages
- Thermal activation of foundation piles is possible for all drilling depths and diameters.
- Spiral design ensures maximum functionality with minimal cost.
- Quick installation of pipelines in the reinforcement cage prevents construction disruptions.
- Optimal exploitation of geothermal resources makes it the most energy-efficient solution.
- Extremely low investment costs compared to other geothermal heat exchangers ensure maximum profitability.

System Components
The modular system includes energy piles, connecting lines, building ducts, and distributor units, providing integrated geothermal system solutions that eliminate interface problems and simplify planning and construction processes.

Available Designs
- Spiral Shape: Most profitable design with high functionality and low costs.
- Meander Shape: Frequently used but considered outdated.
- Single Loops: Low pressure losses but high costs and no controlled volume flows.

Experience and Expertise
GWE pumpenboese GmbH is a technological leader in geothermal energy within specialist foundation engineering. They have successfully implemented thermal activation in various foundation engineering processes, including cast-in-situ concrete piles, CFA piles, pressure-grouted piles, ductile piles, MIP walls, and excavation pit retaining walls.

Case Study
"The Circle" project in Switzerland involved the geothermal activation of over 700 foundation piles, showcasing the practical application and success of energy piles in large construction projects.
