How Much Heating Oil Does a House Use in CT?

Most Connecticut homes use very different amounts of oil depending on home size, insulation quality, and how cold the winter gets.

Quick planning ranges

  • Smaller efficient homes: often around 400 to 700 gallons per heating season.
  • Mid-size older homes: often around 700 to 1,000 gallons.
  • Larger or draftier homes: often 1,000+ gallons.

What changes your usage most

  • Square footage and layout.
  • Insulation and air sealing quality.
  • Thermostat settings and occupancy schedule.
  • Boiler/furnace efficiency and maintenance history.
  • Outdoor temperatures and wind conditions.

Simple refill planning formula

Track how many gallons you used between two fills, then divide by days elapsed to get your average gallons per day. As temperatures drop, increase your safety margin and reorder earlier.

How to avoid run-outs

  • Reorder before the tank drops below about 1/4 in colder months.
  • Set a recurring reminder once per week during peak winter.
  • Keep your fill pipe and driveway clear for delivery access.
