Prototyping Intern

Are you passionate about technology and the environment? Our start-up in the green tech industry (heat pumps) is seeking enthusiastic individuals eager to gain hands-on experience and make a difference in the world of sustainable technology.


At GEHECO we believe real physical tools are what we need in the energy transition. One of the big sources of CO2 is the heating of homes, and currently many home owners search for solutions how to electrify the heating of their homes. Today, the most efficient solution, the water- water heat pump is available only to a (rich) few. Our mission is to enable all home owners to heat their home with the superior water- water heat pumps, by solving it’s Achilles’ heel, which is the drilling of the well.

GEHECO is a start-up which focusses on laying the wells for water-water heat pumps in existing houses. In order to do so, we are designing a revolutionary new drill tool that is able to place the well, ultimately from within the home. GEHECO likes to actively contribute to the energy transition by helping our future clients in efficiently CO2 neutral heat their houses.

GEHECO is a young and forward-thinking company at the forefront of the heat pump technological innovation. At GEHECO, we value creativity, collaboration, and a commitment to pushing the boundaries of the status quo.
