Under these conditions, a typical home uses about 5.3 gallons of
In general, we will see the temperatures fluctuate from the 20s to 40s during the cold season and average at 30 degrees Fahrenheit. Therefore, the average home utilizes around 5.3 gallons of heating oil per day. This means that a full tank will last about 52 days or one month and three weeks.
In the U.S., the average household that uses oil for heat uses about 500 gallons between October and March (182 days). If you divide the average amount of fuel used (500 gallons) by the number of days (182), the average home uses about 2.75 gallons of oil each day.
Calculating Oil Consumption
Annual Consumption: Homes ranging in size 2,000 sq ft might use between 800-1,000 gallons of heating oil per month. Daily Usage: During the winter season, daily oil consumption can vary. On average, it has been estimated that a 2,000 sq ft home might use around 7 to 9 gallons per day.
How long should 100 gallons of heating oil last? Using the calculation above, 1.7 gallons per hour x 10 hours a day (assuming the number of hours you spend at home is 10 hours) = 17 gallons a day. That means, 100 gallons of oil will last you about six days (100-gallon tank / 17 gallons per day = 5.8 days).
This can equate to anywhere around 200-250 hours. For a smaller property that requires little heating, or is assisted by another form of heating, 500 litres should be fine. For bigger properties, older properties, or for residents that prefer it toasty, tanks around 2,500 litres are much better suited.
If your 275-gallon tank is full at the start of a 40-degree weather spell, the oil will last for approximately 74 days, or 2.5 months. Granted, you would be lucky if the temperatures in your area drop no lower than 40 degrees during the winter months.
For every 1,000 square feet of living space, your heating oil needs can be estimated based on the average outdoor temperature as follows: 10°F: Approximately 3.27 gallons per day. 20°F: Approximately 2.67 gallons per day. 30°F: Approximately 2.07 gallons per day.
If you have a 275-gallon tank, which typically holds about 230 gallons of fuel (the rest is needed for air), a full tank should about five weeks in a 2,000 square foot home. Overall, you should expect to use somewhere between 700 and 900 gallons during an average heating season in our area.
The primary disadvantage of heating your house with oil is that it's generally the most expensive heating fuel. But that's not the only problem. Burning heating oil in your home isn't the healthiest. It can contribute to indoor air quality issues and carbon monoxide off-gassing.
If your house is totally average and it's the middle of winter then a full tank of heating oil will last approximately 3-4 weeks. Remember to always Order at a Quarter!
For a general estimate, you can figure that the average household uses about 0.8 to 1.7 gallons of oil per hour during cold weather. When the temperature is around 50 degrees, that might mean you only use a couple of gallons a day.
Considering all of these factors, it's difficult to get a definitive answer on how long heating oil should last. There is a standard rule that 1,000 litres should last 6 months, but everything discussed can play a part in this.
You Can Save Money on Fuel
If you ask homeowners if it is worth buying a house with oil heat, there's a good chance they'll say “yes.” This is due in part to the fact that oil heat is highly energy efficient. In today's day and age, oil-powered heating systems are known to have an efficiency rating of 95%.
Oil heater: Cost to run
According to Home Inspection Insider, running a 1,500-watt oil heater costs an average rate of 10 cents an hour. If you run your heater for eight hours a day, it would cost you around $25 a month.
The average monthly home heating oil bill is $154.92. Your average monthly propane bill will run about $134.86, again, with considerable variation by location, provider and the heating efficiency of your home.
For an “average size” home of 1,650 square feet, you can estimate that you'll use about 5 gallons of fuel oil per day to keep your home heated through Pennsylvania's cold months. If your home has an older heating oil system, it won't work as efficiently.
The figure on average is about 5.5 litres per day. This assumes that each day of usage will be the same, but seasonality is a significant factor here.
Based on the calculation provided, if you consume 1.7 gallons of oil per hour and spend approximately 10 hours at home each day, you would use around 17 gallons of oil daily. Consequently, a 100-gallon tank would last you approximately six days (100-gallon tank divided by 17 gallons per day equals 5.8 days).
Your oil tank
Equally, if you have an inefficient heating system, this can also burn through heating oil quickly and therefore increase your oil consumption. The size of your oil tank will also determine how often the heating oil in your tank needs to be topped up.
3 inches or 8cm from the bottom of a 1,200 litre tank means you have approximately 100 litres of oil left. That will last the average home between 5-10 days depending on usage.
Air in the Fuel Lines: Running out of oil can cause air to get into the fuel lines. If this happens, you'll need to bleed the fuel lines to remove the air before your system can operate properly again. This is best done by a professional.
How long does it take? It's important that you try to not rush the process of preparing oil, in order to avoid overheating it. The best way to heat the oil is by placing it on a burner at around medium heat, on this heat setting it should take around 5 to 10 minutes to reach the right starting temperature.
Tank size: 275 gallons (holds 250) Reorder point: 1/4 tank or 68 gallons. Usable gallons between fills: 250-68 = 182 gallons. Number of Days Between Fills: 182 gallons / 5.2 gallons/day = 35 days.
