Frequently asked questions
How do I know how much propane I have left?
Read the dial gauge on top of the tank — it shows the percentage of the tank that is liquid propane. Because tanks are only filled to about 80%, a full tank reads roughly 80%. Multiply your tank’s water capacity by the gauge percentage to estimate gallons remaining (a 500-gallon tank at 30% holds about 150 gallons).
At what percentage should I refill my propane tank?
A common rule is to order when the gauge reaches 25–30%. That leaves enough buffer to cover delivery lead times and a cold snap, so you’re never running on fumes. If you’re on will-call (you order yourself), set your reorder point a little higher in winter.
How much propane does a house use per day in winter?
A home heated with propane typically burns 2–5 gallons per day in cold weather, depending on home size, insulation, and temperature. Milder days use less; an extended cold snap can push usage well above average — which is why a flat estimate often runs out sooner than expected.
How long will a 500-gallon propane tank last in winter?
A 500-gallon tank holds about 400 usable gallons. At 3–4 gallons per day for whole-home heat, that’s roughly 3–4 months — but a hard winter or a larger home can cut that significantly. Tracking your actual daily usage gives a far more reliable refill date than the average.
Does cold weather make propane run out faster?
Yes. Propane heating usage is driven almost entirely by how cold it is outside (measured as heating degree-days). A week of below-average temperatures can dramatically increase your daily burn, which is why a weather-aware forecast beats a fixed gallons-per-day estimate.
