Oil Tanks
A healthy heating oil tank is an important part of your heating system. It doesn’t just store your heating oil; it protects the quality of your heating oil. Quality oil is essential to the dependability and efficiency of your heating system.
Aboveground Heating Oil Tanks
The majority of heating oil tanks in the Baltimore area are 275-gallon “aboveground” tanks. An aboveground oil tank may be located in a basement area or outside the house.
Oil Tank Inspection: Our service technicians will inspect your above ground oil tank as part of your annual system tune-up. Additionally, our oil drivers keep a watchful eye when making deliveries to outside oil tanks they can see. And while you can count on us to let you know if they see signs that your tank is weakening, it’s important to know that once that process begins, a tank can quickly become unusable.
Oil Tank Life Span: There are many factors that determine how long an aboveground heating oil tank will last. The average life of an aboveground heating oil tank is approximately 15 years. Outdoor oil tanks that are exposed to the elements may not last as long.

Oil Tank Maintenance
Your oil tank is part of your property and requires upkeep. These simple steps will help keep your above ground oil tank in good shape and prolong its life.
- Keep the area around your heating oil tank clear and as visible as possible. Do a visual inspection of your tank at the beginning and end of each heating season.
- Remove debris that could dent or puncture your oil tank.
- Look for loose or chipped paint on your tank. Brush any exposed metal lightly with steel wool before applying touch-up enamel.
- Look for oil stains on the underside of your tank. If you see any stains on the tank or floor, please call us immediately!
- Do not touch any part of a tank that appears to be rusted or damaged.
- Be mindful of fuel quality to help prevent the formation of tank sediment, which can shorten the life of your tank and cause system breakdowns.
- Call us if you have any concerns about your heating oil tank! We are happy to help.

Underground Heating Oil Tanks
One of the advantages of an underground heating oil tank is that it is hidden. Unfortunately, this is also its biggest disadvantage.
Not only can an underground oil tank not be seen, its age is often unknown. In these situations, the tank is presumed to be as old as the house it serves.
Telltale signs of a leaking underground oil tank include: increases in fuel consumption that are unrelated to household usage; frequent burner failures linked to water-contaminated fuel.
While there is no single factor to indicate the condition of an underground tank or how long it will last, we recommend replacing any underground oil tank that is more than 25 years old.
