The average propane consumption per year for whole-house heating is estimated to be between 1200 and 1500 gallons per year for a 2,200 square foot home. However, the amount of propane a household uses varies depending on its specific uses in the household.
Households that use propane for specific tasks use much less propane per year than those that heat their entire house with a propane heating system. Typical use for households with a propane hot water heater is between 300 and 400 gallons per year. Cooking with propane uses approximately 50 gallons per year, while cooking and using a propane clothes dryer consumes between 100 and 150 gallons per year.
