All Home Heating Oil is Not the Same - Carlisle Petroleum

All Home Heating Oil is Not the Same

Jan 12, 2020 | Main Blog | 0 comments

People in this country rely on different sources of energy to heat their homes and keep themselves warm during the winter season. Although LPG, electricity, and other renewable sources are familiar, there is one that stands out: home heating oil. The most distinctive characteristic of heating oil is the fact that it is delivered by oil delivery companies and it is stored in a tank that is commonly placed or situated beneath the home.

But contrary to what most homeowners who use heating oil believe in, not all home heating oil is the same. Even if they all look alike and serve the same function, heating oil is actually distinguished into different types and grades. In this article, we look at those differences and compare each one.

Types of Heating Oil

Generally speaking, there are two types of heating oil intended for domestic or home heating. They are:

Gas Oil – This is also referred to as red diesel or the 35 second oil. It is distinguished by the fact that it is heavier and is primarily used in older generation of boilers, more specifically those once used in commercial and agricultural use.

Kerosene – Kerosene on the other hand is the second type. It is known as the typical heating oil and also called 28 second oil. Its main advantage is the fact that it is lighter and cleaner.

If you recently moved into a new house or property, the kind of oil you will be using primarily depends on the type of heating system that is already in place. In most instances, there is a clear label on the boiler or the tank, giving you the right instructions on what type of heating oil was used previously. If there is no indication, you have to ask a heating oil expert to be sure.


Heating Oil Costs

Furthermore, another manifestation that all home heating oil is not the same is the costs. Kerosene, for one, is considered as the more efficient compared to gas oil. But then again, there is also great emphasis placed on the area where you live and the availability of the type of heating oil in your state or city.

Heating Oil Grades

But aside from the two types, heating oil is also differentiated on grades. Traditionally speaking, there are three different grades along with three intermediary grades. Likewise, each has its own distinctive quality and characteristics. But just a preview of the quality of each grade, the common scenario is that when you choose a higher grade, it also means you will have to spend more on it. Although higher grade heating oil is more expensive, it also burns cleaner, more efficiently, and has lesser impact on the environment.

But just like the types we’ve mentioned earlier, you have to first understand your heating system and your furnace to be able to use the right oil required to keep your home warm during the winter. And for your information, heating oil, as of today, is the second most widely consumed petroleum product, obviously behind only to gasoline.

1 – Heating Oil (Grade) 1 and 2

Number 1 and 2 heating oil is considered as the two most common type used for residential heating. 1 is less expensive compared to 2. Actually, 2 has the same classification as diesel fuel in the United States so most people think they’re one in the same. However, they are not because number 2 is formed during the refining process by heating and then condensing raw crude oil. The best attribute of number 2 is that it is more efficient than other fuel sources for home heating like natural gas, propane, kerosene, or even electricity.

2 – Intermediary

Intermediary grade heating oil on the other hand is mostly blended mixtures of higher grades and lower grades. They are mostly used for industrial and commercial burners with better efficiency. However, they are expected to be more expensive.

3 – Number 6

The last grade is called heating oil number 6. This one is the least expensive of the three standard heating oil grades. However, as the price implies, it is also the dirtiest. Using this type of home heating oil will most likely correspond to more frequent maintenance and cleaning of your furnace and heating system. Because of the high concentration of pollutants and sulfur, it is gradually being phased out.

Indoor Air Quality

Health problems like allergies and asthma can be aggravated by poor indoor air quality. There are solutions to cleaning and improving the air in your home. Identify the sources of air pollutants and eliminate or reduce them. Although, it is almost impossible to remove every source that may emit pollutants, reducing them will contribute to a healthier environment. Frequent dusting and vacuuming can reduce the amount of dust particles in the air. Bacteria and volatile organic compounds are more difficult to remove. A Lennox Healthy Climate PureAir air purification system can help to remove irritants and purify your home’s air. To find out more about how a PureAir system can improve the quality of your indoor air call Carlisle Petroleum for a no cost in-home estimate and start breathing easier.

Ductless Heating and Cooling

Ductless HVAC systems can be a solution to heat and cool areas that are not easily accessible for duct installation. This application can be perfect for additions and older homes where the integrity of the structure needs to be maintained. Ductless heating and cooling systems offer higher efficiency and several indoor units can be installed with just one outdoor unit. Please call to schedule a free in-home estimate.


In the winter humidity is low and heating systems can make indoor air dry. Dry air can cause static electricity, dry itchy skin, nose bleeds and aggravates respiratory ailments like asthma, colds and sinus infections. When we humidify air it feels warmer and more comfortable and can save on heating costs. Portable units only humidify one room and are inconvenient to maintain. A Lennox Healthy Climate humidifier can release moisture and circulate it through your entire home when the heating system is in operation. To find out more about the best solution to improve your home’s indoor air quality call Carlisle Petroleum and speak to a Home Comfort Advisor.
