The efficiency of a geothermal loop system will depend on whether it continues to perform as it was first designed.  If the system becomes blocked with residues or as is sometimes the case, with iron related bacteria contamination, then the systems can become inefficient and sometimes even stop working.

Recently treatments have been carried out on large industrial heating systems in Italy.  3 deepwells running 9 systems totalling 150,000 ltrs with over 20km or pipework from 250mm to 8mm diameter were cleaned using nearly 4 tonnes of product.  Specific procedures and methodologies were developed to ensure the correct amount of product was distributed throughout the whole sytem.

The treatment was carried out whilst maintaining  all the pumping plant within the well, down time reduced, while still achieving an effective clean.  By achieving a successful treatment the system now runs efficiently and as initially intended.  In addition no major maintenance work or replacement of key components has been required saving many thousands of Euros
