How to Estimate Your Daily Heating Oil Use
Tevis Energy has options to prevent tank run-outs all year.
As you might imagine, there are a wide variety of factors that a company like Tevis Energy needs to consider when developing an automatic heating oil delivery schedule for our customers. Heating oil consumption is far from uniform throughout the year. In the middle of summer, for example, your home’s daily fuel consumption may be close to zero.
In this article, we’ll explain how we account for how quickly a home will consume heating oil.
What Affects How Much Heating Oil You Use?
Daily heating oil consumption can change significantly throughout the heating season, and even from one day to the next. The amount of fuel your home needs depends on a combination of factors. Here are three of the biggest ones:
- Outdoor temperatures: The colder it is outside, the more work your heating system must do to keep your home comfortable. Maintaining a thermostat setting of 68°F on a 10°F day requires considerably more heating than maintaining that same indoor temperature when it’s 40°F outside. That’s why a stretch of frigid weather can cause your daily oil consumption to climb quickly.
- Your home’s size and level of insulation: The amount of space you’re heating and how well your home holds onto that heat also affect fuel consumption. A big, drafty house will take more fuel to heat than something more compact. Improvements such as better insulation and air sealing can help reduce the amount of heat your home loses, potentially lowering the amount of fuel your heating system needs.
- The age and condition of your heating system: Your heating equipment plays an important role in determining how efficiently you use heating oil. Older systems may operate at efficiency levels of 65% to 70%, while newer high-efficiency equipment can reach 85% to 90%. Keeping your system properly maintained can also help it perform more efficiently, allowing you to get more heat from the oil you burn.
Quick Guidelines for Estimating Your Heating Oil Usage
Getting an exact figure requires close monitoring, but you can arrive at a solid estimate using a simple temperature-based rule of thumb. For a standard home, roughly 2,000 square feet with average insulation, usage generally breaks down like this based on outside temperature:
- Mild winter day, 50°F average: Approximately two gallons per day
- Average winter day, 30°F average: Approximately 3.5 to five gallons per day
- Cold winter day, 15°F average: Approximately six to eight gallons per day
- Deep freeze, 0°F or below: Typically nine or more gallons per day
Calculating Your Usage by Checking Your Gauge
For a more precise number, try this simple exercise over the course of a week:
- Check your gauge: Note where it stands. For example, a standard 275-gallon tank holds about 240 usable gallons, so a half-full tank is roughly 120 gallons.
- Wait a week: Go about your normal routine.
- Check the gauge again: If it’s dropped to 3/8, you have about 90 gallons remaining.
- Run the numbers: You used 30 gallons over seven days. Divide 30 by seven, and you get roughly 4.28 gallons per day.
