Heating oil is widely used across the country, making it the primary heating source for nearly 6 million households. Since it’s so vital for everyday use, monitoring your oil tank is key. Sludge buildup is a common occurrence, and if too much accumulates, your entire heating system could break down. So, how does that sludge get into your oil tank in the first place? Take a look at some contributing factors below and helpful solutions. 

How Sludge Develops in Your Heating Oil Tank

Temperature Changes

As exterior temperatures fluctuate from hot to cold and back again, condensation accumulates within your tank. Water is heavier than your home heating oil, causing it to spread out and settle at the tank’s bottom. As moisture builds up further, it creates a breeding ground for bacteria and fungi, which form a thick layer of sludge. 

Overloaded Filter

Your furnace’s pick-up line is positioned a few inches above the oil tank’s bottom to reduce the chances of picking up sludge instead of oil. But sometimes—especially during heavy rain and snow—sludge can slip past this pick-up line into the filter, the basket-like component that captures it before it reaches the furnace. This filter is cleaned out during every tuneup appointment, but rough weather can cause the sludge inside to accumulate quickly and overflow out of the filter into your oil tank.

Preventing Sludge Buildup

Since temperature changes are impossible to avoid, regular maintenance will help your tank stay inaccessible to condensation. A full home heating oil tank, regardless of season, can prevent that extra sludge from accumulating.

The more heating oil that’s inside, the more difficult it is for water to reach the bottom and form sludge. An annual inspection and tuneup will inform you of current sludge levels and your tank’s overall condition, so make this a priority before the cold weather kicks in. A professional will tackle your maintenance needs quickly and efficiently, including cleaning out the tank.
