Q: What is heating oil?

A: Heating oil, known as oil, fuel oil, home heating oil, and HHO, is a low-viscosity liquid petroleum fuel product that is refined and used as a heat source.


Q: Is home heating oil safe?

A: Yes, heating oil is a safe and nonexplosive fuel source. It is fire-resistant because of its high flash point of 140 degrees Fahrenheit. It also produces visible warning signs like smoke if a heating system malfunction were to occur, meaning oil users can benefit from home security.


Q: What are the main uses for heating oil?

A: Heating oil is primarily used for heating and water heating. It can be used in furnaces, boilers, and water heaters that are oil-fired.


Q: How can I monitor my home heating oil levels?

A: The simplest way is to read your oil tank gauge, which is like your car’s gas gauge. You should order a refill when your home heating oil tank gauge reaches ¼ capacity.


Q: I ran out of oil! Can you make an emergency delivery?

Unfortunately, we cannot make emergency deliveries. To reduce your risk of an oil runout, place an order when your tank gauge shows no lower than ¼ capacity remaining.


Q: How do you read an oil tank gauge?

A: Read a tank gauge just like your car’s gas gauge: Full, ¾, ½, ¼, and Empty. You can find the small circular glass or plastic gauge on the top or side of your oil tank. Be sure to check it frequently and place an oil order before the bottom of your gauge reaches the 1/4th marker.


Q: How does the weather affect heating oil usage?

A: The colder the temperatures are, the more heating oil a furnace or boiler will need to provide warmth. During the dead of winter, you will go through oil more quickly than in spring or fall. Other factors can affect heating oil usage too, such as personal heating preference, home size, and furnace or boiler efficiency—that’s why it’s so important to frequently check your oil tank gauge.


Q: What appliances can I use with heating oil?

A: The most common oil-fired appliances are furnaces, boilers, and water heaters.


Q: What are the advantages of using home heating oil?

A: Heating oil has long since been recognized as a safe heating fuel, since it is nonexplosive. It’s also abundant, burns efficiently, and is getting cleaner and cleaner with environmental advancement technologies such as ULS and biodiesel.
