Regardless of the quality of the heating oil, it inevitably undergoes a natural aging process over time, even without external influence. Due to heat, exposure to light, contact with oxygen, microorganisms, the catalytic effect of metals, and chemical compounds, certain residues form during the storage of heating oil. These accumulate along with condensation water at the bottom of the tank and turn into sludge. A tank revision ensures that all residues are removed.

What Does a Tank Revision Include?

The first step in a tank revision is to pump out the remaining heating oil from the tank. Then, all the contaminants that have settled on the inside of the tank are removed.

All removable residues, water, and sludge are eliminated. This ensures that no dirty heating oil is drawn in and supplied to the oil burner. To prevent pitting corrosion, the inner walls of the tank are thoroughly inspected.>

Once the cleaning is complete, a professional visual inspection of the tank is carried out. During this inspection, the heating oil tank is checked for cracks or other corrosion damage.

The proper disposal of waste produced during the tank revision and the return of the remaining oil to your tank are included in the revision service.

How Often Should a Tank Revision be Done?

The frequency of cleaning a heating oil tank depends particularly on the current condition of the tank system. In general, it is advisable to carry out a thorough tank revision on steel tanks every 5 to 7 years and on plastic tanks every 7 to 10 years.

Tank Revisions with Midland Partner “Erismann AG”

Since January 1, 2007, tank system owners (depending on the water protection zone) are no longer required by the cantonal authority to have a tank revision. Nonetheless, it is crucial to have the tank inspected by a specialist at your own responsibility.

Midland has been successfully cooperating with the company “Erismann AG,” based in Meisterschwanden, for many years in the area of tank revisions.
