Heating Oil Tank Condensation: How To Prevent It

The seasons are changing here in Connecticut, and soon it will be time to give your heating system a well-earned rest of the summer. But before you do that, we suggest doing two things, if you haven’t already: schedule your annual heating maintenance and contact us for a heating oil delivery.

The first of these suggestions probably makes sense, since regular maintenance helps you keep on top of small issues before they become bigger problems for your furnace or boiler. But why top off your tank when you’re not going to use your heating system for another few months?

To prevent water build-up in your heating oil tank.

You see, a heating oil tank that is less than half full tends to develop a build-up of condensation (water) on its inner walls (the way a cold glass builds up water on its sides during the summer). That’s bad news for two reasons: first, the bacteria that already live in your heating oil thrive in damp places, and when they multiply, they turn your heating oil into a thick sludge that clogs your fuel lines and burner nozzle.

Condensation can also rot your tank, creating a second problem. Water, which is heavier than oil, will sink to the bottom of the tank, rotting it from the inside out. That’s a big problem that could be difficult to see coming and costly to remediate.

The bottom line is that a build-up of condensation is not good for your heating oil tank, and keeping oil in your tank during the offseason is one of the best ways to prevent it. Topping off your tank now could also be a good way to save some money, since heating oil prices are often at their lowest during the offseason.
