Project Engineering

Development of the executive project for the renovation of the thermal production system at the Vall de Núria complex.

The project proposes the progressive decommissioning (5 phases) of the thermal production of the buildings with diesel boilers and expanding the current production with geothermal heat pumps, creating a network with two production plants.

The current production room at Sant Josep is expanded with 240 kW up to a total of 480 kW, and a new production room is created at Sant Antoni with 360 kW, reaching a total of 800 kW of geothermal production.

Installation of 10 geothermal heat pump units, 2 heat exchange fields with 27 and 54 100-meter deep wells, and a network of connections between production stations for distributing heat to ACS production stations and heat distribution to plants.
