Heating Oil Consumption Estimator

Estimate heating oil consumption for a winter season using home size, insulation level, climate severity, and heating days.

Estimate heating oil usage for a winter season using a simple model based on home size, insulation/efficiency, climate severity, and heating days. This is a planning estimate — your actual usage can vary by thermostat settings, heat loss, and weather.

Use conditioned (heated) square footage if possible.

Typical range: 120–200 days depending on location.

This adjusts consumption up/down relative to an average home.

Colder climates generally require more heating energy per day.

Default is 1.0. If you have past winter data, you can calibrate this to match your real-world usage.

Estimated gallons/day: 2.00 gal/day

Estimated season usage: 300 gallons

Approx season length: 5.0 months → 60 gallons/month (average)

Factors applied: insulation ×1.00, climate ×1.00. This is a planning estimate — real usage varies with weather, thermostat settings, and heating system efficiency.

How to use this heating oil consumption estimator

  1. Enter your home size (square feet).
  2. Choose insulation/efficiency level.
  3. Choose climate severity (mild/average/cold).
  4. Enter heating season length (days) or use a typical range.
  5. Review estimated gallons for the season and average gallons per month.

Example

For a 2,000 sq ft home, average insulation, cold climate, and 150 heating days:
