Heating oil sludge is the leading culprit of many heating system problems. That thick, black mixture of dirt, rust, and oxidized fuel can clog filters and force your equipment to work harder to provide heat, reducing efficiency. Left unchecked, it can cause heating system breakdowns. And if you have an older tank, that gunk can corrode your tank from the inside out and lead to a tank failure, which can be very costly to remediate.
If your heating oil tank sits empty in the warm summer months, condensation forms on the interior walls of the tank. Because water is denser than heating oil, it drips down and sinks to the bottom of the tank, where it becomes an ideal environment for bacteria and other microorganisms to turn it into sediment or sludge that corrodes your tank.
The line that draws oil to your furnace is located several inches above the bottom of the tank to avoid pulling sludge into the supply line. However, when you get a fuel delivery, it can stir up the sludge from the bottom of the tank and it can get drawn into your system.
While it’s possible to get rid of sludge, it’s far easier to prevent it. Here are three measures to stop or slow the formation of sludge in your tank.
Over time, some sludge will accumulate in your tank. If enough sludge accumulates, you’ll need to get rid of it. Your best option is working with a waste-oil contractor. They can drain your tank quickly and safely, saving you money on repairs, improving performance and preventing bigger problems.
If your tank is very old, you may want to consider replacing it. Older tanks are made of steel and have varying thicknesses, some with only single-wall construction. They are much more susceptible to corrosion. Newer tanks are made from plastic and fiberglass and are designed to last 50 years or more.
