Should you be worried if you smell heating oil?
Oil-burning heating systems are safe as long as you know how to use them correctly. However, some of you may be wondering if an odor of heating oil in your home is cause for concern.
Although the problem is usually one that’s easy to fix, you should never wait to take action because, if the situation persists, the consequences could be serious.
Possible reasons for an odor of heating oil in the home
A fuel oil spill
An odor of fuel oil may be an indication that there’s been an oil spill in your home. If your heating equipment is a portable system, it may have tipped over, spilling the oil contained inside.
In the case of stationary heating equipment, the tanks or pipes that pump the oil can leak, resulting in that troubling odor. When the spilled oil comes into contact with wood, fiber or concrete, it can penetrate deep into the material, causing serious damage. That’s why it’s important to act quickly so you don’t end up having to pay for additional repairs and cleanup.
An empty tank
Since propane is odorless, manufacturers add a chemical called ethanethiol (commonly known as ethyl mercaptan), which mimics the odor of rotten eggs, thus making the gas easier to detect. It’s a clever safety measure that enables you to react more quickly in the event of a leak or spill.
When the tank is empty, the ethyl mercaptan tends to remain at the bottom, thus magnifying the strong odor.
Turn the valve clockwise to close it and immediately contact your supplier to come and refill the tank. While you’re waiting, open the windows to air out the house and get rid of as much of the odor as possible.
A crack in the fuel oil burner
The smell of oil can also be the result of cracks in the fuel oil burner. Since igniting oil exerts pressure on the compartment, cracks can form, allowing the oil to escape, inevitably causing an odor. If you fail to address the problem, the cracks can enlarge over time, resulting in damage that’s more significant.
A poorly vented heating system
A defective or clogged ventilation system can allow fumes to escape and flow back into the home.
The situation isn’t dramatic if your home avails of a good ventilation system. But if it doesn’t, the unvented fumes can present a health hazard. In general, the odor of gas is easy to detect; however, carbon monoxide, which is odorless, can pose a serious problem in an enclosed space.
It’s ideal to have your equipment inspected before the arrival of cooler weather. Experts recommend having fuel oil furnaces inspected and serviced annually, and gas furnaces, every two years. If your equipment includes a humidifier, this module needs cleaning every year.
Beware of a persistent odor of oil
If you smell oil in your home, it isn’t dangerous if you address the problem quickly. However, if the odor persists, the risks to your health and that of your family are very real. Symptoms may include dizziness, headaches, nausea and irritation to the eyes, nose and throat.
