Why us

With 25 years of experience exclusively in the field of geothermal energy, Nikolaos Psarras Geothermal Engineering has established itself as a trusted consultant.

Depth of geothermal systems
We offer appropriate equipment for the installation of geothermal systems, up to 320 metres in depth, in order to take advantage of the high and stable temperature of the rock beds as well as the high degree of efficiency throughout the year. At the same time, we reduce the number of boreholes, and the size of surrounding space occupied due to geothermal energy activity.

Saving Wastewater

We implement systems that conserve natural resources throughout the construction of any geothermal project, thus striving to protect the environment and save costs at the same time. In this way we emphasize our corporate social responsibility while also aligning ourselves with LEED & BREEAM green building certifications.

Easy transfer of heat

We use materials that lead to high thermal conductivity, i.e. the easy transfer of heat to and from the ground maintaining the highest degree of efficiency. With this method less metres of geoexchange piping are required.

Purity of quartz sand

We use pure quartz sand for easy and continuous transfer of heat, without any thermal entrapment. These materials result in trouble-free diffusion, uniform heat transference, and a high degree of efficiency for the system.

Particle size to avoid sedimentation
We use materials with very small particle size in order to avoid sedimentation, stratification and heat entrapment, while at the same time reducing the permeability of the geothermal system from its surrounding environment.

Antifreeze Solution
Our systems don’t use antifreeze solution because we study soil unaffected by temperatures, aiming for the highest possible degree of efficiency and conservation that geothermal energy promises. In this way, we achieve minimal maintenance and a long life-span. The use of antifreeze solution serves low ground temperatures, i.e. in geothermal systems of lower efficiency.

Thermal Response Test Capabilities

Each project, a new philosophy…

We have the appropriate tools (thermal response test) with which to measure the capacity of heat transference from and to the ground, for geothermal exchangers located at a depth of up to 320 metres.
