Winter fill calculator

Worked example

200 gallons at $5.54/gal on will-call: $1108.00. Auto-delivery adds $0.05/gal: $1118.00. Cap programme adds a $0.30/gal cap fee non-refundable: $1168.00 ceiling exposure. Cold winter (+15% HDD): 230 gallons at $5.54 = $1274.20.

Gallons from sqft, rough estimate

• 1,500 sqft, average insulation, climate band 5 (NY/MA): ~650 gallons/season.
• 2,000 sqft, average insulation, climate band 5: ~825 gallons/season.
• 2,500 sqft, average insulation, climate band 6 (ME/NH): ~1,150 gallons/season.
• 3,500 sqft, average insulation, climate band 6: ~1,600 gallons/season.

Use last winter's invoices if you have them. The sqft estimate is ±20%.
