What is a common aftermath of not treating the oil tank for sludge when the filter is dirty?

When an oil tank is not treated for sludge, it can lead to poor heating performance. Sludge is a by-product of the oil combustion process that can accumulate at the bottom of the tank. When this sludge is not addressed, it can clog filters and impede the flow of oil to the burner.

As the filter becomes dirty and obstructed, less fuel reaches the burner, causing inadequate combustion. This can result in lower heat output, longer heating cycles, and inconsistent temperature control within the space being heated. Additionally, the presence of sludge can cause the burner to malfunction or fail, further exacerbating heating issues.

In summary, neglecting sludge in the oil tank directly impacts the system's heating performance, leading to inefficiencies and potential breakdowns in operation. Effective treatment and maintenance of the tank are essential for optimal performance and reliability of the heating system.
