Gérard Barré heating system
In December 2001, Gérard Barré’s heating system, installed just one year previously, was shutting down randomly, constantly switching the boiler to “safety mode.” The temperature in his apartment varied between 12 and 15°C!
After numerous call-outs, the boiler mechanic maintaining the system decided to check the state of the fuel oil in the polypropylene tank (1,500 litres). On inspection, he noticed black oily deposits stuck to the wall of the tank. This pollution had been altering the quality of the fuel oil for quite some time.
The management board of the company Auchan, who supplied the fuel, appointed an expert from Pétrovex to find a solution. After performing an on-site inspection and evaluation, and after taking some fuel samples at the start of January 2002, the expert told Mr. Barré that the quality of the fuel sample was not good, and that, as a result, the supplier agreed to thoroughly clean the tank or to provide a standard exchange and a full tank of fuel in order to settle the disagreement. Finally, in January 2002, the tank was exchanged, and 1,000 litres of oil were provided at the expense of the two companies.
In November 2004, the heating system once again began to stop at random, switching the boiler to “safety mode”. The boiler had been inspected in March 2003, and cleaning and annual inspections were therefore up-to-date. But the boiler was no longer working!
Therefore, Gérard Barré got back in touch with the mechanic who had installed the boiler, who discovered the same strange findings that he had made in December 2001: the state of the tank that had been replaced in 2002 was now exactly the same as the old tank. He also noticed that the jet nozzle and the heating system filter were abnormally and excessively clogged.
In January 2005, when representatives from the fuel oil supplier doubted his statements and failed to propose a solution, Gérard Barré decided to test the abilities of Xbee biotechnology on his tank, without any prior cleaning.
In September 2005, the level of fuel was lower, and Mr. Barré could see that the signs of pollution had already disappeared by 80%. Treatment continued until the start of March 2006, when the tank was almost empty, and the walls were clean. The only trace was a small amount of residue, and this was fully eliminated with the next treatment. In addition, thanks to improved combustion, annual fuel consumption decreased by approximately 15 to 17%.
“The natural action of the Xbee enzyme reduced traces of pollution by 90% over the course of one year and with two full tanks of fuel oil. Just one treatment of 450ml for a first full tank of 1,500 litres of fuel in January 2005, and a maintenance dose of half a bottle (225ml) in the second full tank in September 2005 were enough to guarantee the result as shown by the photograph from March 2006” - Gérard Barré
