JANSEN hipress

The most powerful ground source heat loop in the world

JANSEN hipress reaches new dimensions in geothermal energy. As the most powerful ground source heat loop in the world, it has the lowest hydraulic resistance in relation to the installation diameter required.

The Earth is an immense energy store. Jansen is an expert in making this store accessible for heating or cooling. Because the Earth's temperature increases with increasing depth, the energy requirement of large buildings can be covered using deep ground source heat loops even if space is limited.
