Do heating oil tanks corrode from the inside out?
According to a 2-year study done in the State of Maine, of the 498 spill incidents that were reported, 17% of oil spills resulted from internal tank corrosion. Not every tank will have internal corrosion because the amount of moisture that sits on the bottom of the tank will vary depending on volume of use. A good practice for homeowners is to keep their heating tank full during the summer. Less space in the tank means less humidity allowed inside of the tank, which means less water accumulation over time.
