Geothermal maisonette in a central area of Heraklion

Here was a complete application for the ideal heating and cooling of a house with minimal operating costs, using a geothermal heat pump in combination with roof cooling in the concrete core and underfloor heating.
Maisonette in a densely populated area, where we placed in a limited area a closed geothermal field, as we took advantage of both the horizontal and vertical sides of the excavation for cleaning concrete.
