Why It’s Important to Keep Your Oil Tank Full During the Off-Season

Now that we’re finally hitting a stretch of warm weather, the last thing you probably have on your mind is your oil tank. But it’s important to prepare your heating oil tank for the summer months – and the best way to do that is to make sure you go into summer with a full tank of heating oil.

Here’s why. In warm weather, condensation can easily form inside a near-empty heating oil tank because it has more air than fuel. Because water is denser than heating oil, it will settle to the bottom of your tank. This will attract micro-organisms that live in water. These organisms will eventually die off, but their presence will create sediment at the bottom of your tank. This sludge can get into your fuel line and clog it, resulting in a heating system breakdown.

Need a second reason to keep heating oil in your tank in the months to come? How about tank failure? The same condensation that results in sludge can also corrode your tank from the inside out – a big problem that could be difficult to see coming and extremely costly to remediate.

The bottom line: condensation is damaging to your heating oil tank and keeping your tank full during the offseason is a smart way to prevent problems.
