A Guide to Home Heating Oil Tanks

What is the Primary Cause of Home-heating Oil Tank Leaks or Spills?

• Microbial Inﬂuenced Corrosion (MIC) is the internal corrosion of the steel in a home-

heating oil tank by bacteria present in water that accumulates in the tank

• MIC is caused by bacteria that produce an acidic environment which accelerates the

corrosion of the steel, and creates sludge which can plug oil lines and ﬁlters.

• Corrosion occurs primarily on the tank bottom where condensate water gathers

• Damage caused by MIC is easy to miss, as it occurs from the inside-out, in the form of

pinhole leaks or tiny holes

Are There Any Other Causes of Leaks and Spills

Yes:

• Unprotected tanks and fuel lines

• Insufﬁcient support and restraints

• Careless ﬁlling

• Lack of preventative maintenance

What You Should Know About Home-heating Oil Tanks:

Modern home-heating oil tanks are available in a variety of materials. Polyethylene and

ﬁbreglass models are more corrosion-resistant than steel, and are also UV-resistant.

Steel tanks can be ﬁtted with a seamless polyethylene lining, to reduce the risk of internal corrosion

by separating the steel from potentially corrosive tank contents.

These options are more expensive than a basic steel tank, but will greatly reduce the risk of spills.

What Can I Do?

• Follow the Home-heating Oil Tank Checklist provided at the end of this guide

• Enlist the services of a certiﬁed oil burner mechanic to do an inspection, provide expert

advice and make repairs
