What You'll Learn
Heating oil usage varies with the seasons
During winter, heating systems work harder to maintain a comfortable indoor temperature, resulting in higher oil usage. The colder it gets, the more oil is needed. For instance, when temperatures drop to 20°Fahrenheit, a typical household may consume around 7 gallons of heating oil per day. With such demand, a standard 275-gallon tank would be depleted in approximately 39 days. However, winter temperatures often fluctuate, and when they average around 30°Fahrenheit, daily oil usage decreases to approximately 5.3 gallons, making a full tank last about 52 days.
In contrast, during warmer seasons like spring and summer, heating systems are used less frequently, reducing oil consumption. When outdoor temperatures reach 50°Fahrenheit, a household may only use a couple of gallons of oil per day.
The energy efficiency of a heating system also impacts oil usage. More energy-efficient systems have higher Annual Fuel Utilization Efficiency (AFUE) ratings and consume less oil, even during colder periods. Additionally, factors such as home insulation, window quality, and thermostat settings influence oil usage. Well-insulated homes with energy-efficient windows and controlled indoor temperatures can conserve heating oil, while drafty homes with single-pane windows and higher temperature settings will use more oil.
To estimate heating oil usage, homeowners can review previous heating bills, track yearly fuel consumption, and consult neighbours with similar-sized homes. These steps provide a baseline for understanding and planning future heating oil needs, which fluctuate with seasonal temperature variations.

The size of your home matters
The number of people in a household also plays a role in fuel oil consumption. A larger household with more people taking hot showers will use more heating oil to heat the water. Similarly, if the residents prefer to keep the temperature higher, the house will consume more fuel.
The energy efficiency of your heating system is another crucial factor. A more energy-efficient system will use less oil, even during colder days. The efficiency of a heating system can be measured using the annual fuel utilization efficiency (AFUE) rating. A very efficient heating system will have an AFUE rating above 90%, while less efficient models will have ratings below 80%.
Additionally, the quality of your home's insulation can impact fuel oil usage. A well-insulated home will retain heat better, reducing the amount of fuel needed. Upgrading to energy-efficient windows, sealing drafts, and improving insulation can significantly decrease heating oil consumption by retaining indoor warmth and reducing the demand on your heating system.
To estimate your daily fuel oil usage, you can review previous heating bills and track your yearly fuel consumption. Additionally, you can consult your neighbors with similar-sized homes or your local heating oil supplier to get valuable insights and estimates tailored to your home's needs.

The number of people in your home matters
The number of people in your home is an important factor in determining how much fuel oil you will need to heat your home. A larger household will typically use more fuel oil than a smaller one. This is because there are more people carrying out activities that require hot water, such as taking hot showers. The more people in the house, the more hot water will be used, and the more fuel oil will be needed to heat it.
The temperature you keep your home at will also affect how much fuel oil you use. A household that prefers to keep the temperature at 70 degrees will use more fuel than one that is happy with a cooler temperature of 50 degrees. The difference in temperature preference can result in a difference of up to six gallons of oil used daily.
The size of your home will also impact your fuel oil usage. A larger home will need to use more fuel than a smaller one to reach the desired temperature. The median size of a new, single-family home built in 2018 was 2,386 square feet, and this home would use about 0.21 gallons of oil per square foot in the fall and winter.
To conserve fuel oil, you can improve your home's insulation. This will help keep the warm air in and the cold air out. Sealing drafty windows and upgrading to energy-efficient double-pane windows can significantly decrease your heating oil consumption by retaining indoor warmth.
The efficiency of your heating system will also impact your fuel oil usage. A very efficient heating system will have an AFUE rating above 90%, while the least efficient models will have a rating below 80%. A more efficient system will use fewer gallons of oil on a daily basis as it will not be losing" as much heat as a less efficient system.
By taking into account the number of people in your home, your desired temperature, the size of your home, your insulation, and the efficiency of your heating system, you can estimate how much fuel oil you will need to heat your home.

The energy efficiency of your heating system
The efficiency of a heating system, such as a furnace or boiler, is typically measured using the Annual Fuel Utilization Efficiency (AFUE). This rating indicates the percentage of heat the system is able to generate from the fuel it consumes. A very efficient heating system will have an AFUE rating above 90%, while less efficient models tend to fall below 80%. For example, the minimum AFUE rating for a non-condensing fossil-fuelled furnace is 78%.
It's important to note that the type, age, and initial efficiency of your heating system all play a role in its overall efficiency. Older furnaces and boilers were often manufactured with lower efficiency standards and tend to lose efficiency over time. Systems that run on oil, propane, or natural gas typically have maximum efficiencies of about 90-98%. In contrast, heat pumps, including air-source and ground-source types, can exceed 100% efficiency because they transfer heat rather than generate it directly.
When considering an upgrade to your heating system, efficiency should be a key factor in your decision-making process. A newer, more efficient system may pay for itself over time through energy savings. Additionally, you can improve the efficiency of your existing system through proper maintenance and upgrades, such as regular cleaning or replacement of filters, ensuring furniture or drapes don't block heat sources, and sealing air leaks.
The size of your home and the number of occupants also impact the efficiency of your heating system. Larger homes and those with more occupants generally require more fuel to maintain a comfortable temperature. Additionally, individual preferences, such as keeping the temperature higher, will influence fuel consumption.

Insulation and windows
There are several ways to improve the insulation in your home. Firstly, address any cracks, gaps, and insulation deficiencies. Caulking around outlets and light switches can help seal these areas and prevent heat from escaping. Additionally, consider insulating your basement, as it is often a major entryway for cold air. Add insulation to the walls and ceiling to reduce the amount of incoming air, and don't forget to seal around the sill plate.
Another way to improve insulation is by hanging heavy drapes or shades on your windows. This provides an extra layer of insulation and helps keep the warm air inside. If you have drafty windows, try to seal them as best you can. You can use thin plastic sheets and double-stick tape to adhere the sheet to the window frame. Using a hairdryer on the sheet will remove any wrinkles, making it nearly invisible. This creates an air pocket that acts as insulation, keeping the cold air out and the warm air in.
Upgrading your furnace or boiler can also improve insulation and reduce fuel oil consumption. Newer heating systems are designed to be more energy-efficient, with higher AFUE ratings and features that improve efficiency. Additionally, consider getting a Smart Oil Gauge to monitor your hourly usage and determine how improvements to your insulation impact your oil usage.
By investing in proper insulation and addressing drafty windows, you can significantly reduce the amount of fuel oil needed to heat your home, leading to both cost savings and a more comfortable living environment.
