Therefore, it is important that each and every homeowner who uses heating oil knows what the signs of a heating oil leak are.
Warning Signs of a Heating Oil Leak
Here are some common indicators of a heating oil leak to be on the lookout for:
- Your heating bills are suddenly more expensive: If you are suddenly spending more on your heating bills than you previously were and haven’t had your heat on more than usual or set your thermostat to a higher temperature, your tank may be leaking. Oftentimes, an oil leak will cause your heating system to lose fuel. This causes your heating system to use more energy, and this will end up being reflected on your energy bills.
- You smell oil inside your home: Heating oil leaks smell like diesel fuel. This is because certain compounds in the fuel evaporate into the air and turn into a vapor. If you smell something similar to diesel fuel, you may have an oil leak.
- Dead vegetation and plants near your storage tank: Leaking oil can soak into soil and contaminate it. As a result, vegetation and plants can die.
- There is an oily sheen in your home’s water: An oily sheen on the surface of your home’s water is a common sign of a heating oil leak. If this is happening to your home’s water, you should act immediately.
Why You Should Avoid Running Out of Heating Oil
Heating oil leaks aren’t the only problem that you can run into with a heating oil tank. Running out of fuel is also a major potential issue.
Not only does running out of heating oil mean that your home won’t have any heat, but this can also cause a whole bunch of problems for your heating system, such as:
- Strange noises in your lines, oil pumps, or filters.
- Clogged oil filters and nozzles that can negatively impact the efficiency of a heating system.
- Condensation, which can lead to bacterial growth. Bacterial growth can turn any leftover fuel in a tank into sludge.
- Filters that get clogged from feed lines that were filled with sediment and impurities.
