Propane Usage in Hawaii (HI)
About Propane Usage in Hawaii
Hawaii is located in Climate Zone 1, which is characterized by a hot climate with minimal heating requirements. Propane usage is dominated by water heating, cooking, and pool or spa heating rather than space heating. With 0 Heating Degree Days per year, Hawaii's heating demand is well below the national average of 5,000 HDD. This means propane furnaces and heating appliances in Hawaii consume approximately 0% of what they would at the national baseline.
The average propane price in Hawaii is $4.50 per gallon, which is above the national average of approximately $2.50 per gallon. For a typical full-home propane setup (furnace, water heater, cooking range, and clothes dryer), Hawaii homeowners can expect to use approximately 542.9 gal per year at an estimated cost of $2,443.18. This is $2,107.85 less than the national average for the same appliance configuration.
With minimal heating demand, propane usage in Hawaii is primarily driven by water heating, cooking, pool or spa heating, and outdoor living appliances. Optimizing water heater settings and using propane-efficient appliances provides the most significant savings.

Saving on Propane in Hawaii
Reducing propane costs in Hawaii starts with understanding where your propane goes. For homes using propane as the primary heating fuel, space heating typically accounts for 60-75% of total propane consumption, making it the primary target for efficiency improvements. Water heating is usually the second largest use at 15-25%, followed by cooking and clothes drying at 5-10% combined.
With Hawaii's warm climate and minimal heating demand, focus on water heating efficiency and outdoor appliance management. A tankless propane water heater eliminates standby losses from keeping a tank of water hot 24/7. If you have a pool or spa, a quality cover reduces heat loss by 50-70% and significantly cuts propane usage for pool heating.
On the purchasing side, shop around among propane dealers in Hawaii. Prices can vary by $0.30-0.50 per gallon between competitors in the same area. Pre-buy contracts that lock in a summer price for winter delivery typically save 10-20% compared to market-rate pricing during peak season. If your usage is high enough, consider a larger tank (500 or 1,000 gallon) to take advantage of bulk delivery pricing, which is typically $0.10-0.20 per gallon cheaper than small-volume deliveries.
