Choosing between propane tank sizes comes down to how many appliances you run, your climate, and how often you want to refill. The 500 gallon is the most popular residential size because it balances upfront cost with enough working capacity to last through a full heating season in most moderate climates without a refill.
If you live in a cold climate or run multiple high-consumption appliances furnace, generator, pool heater size up to 1000 gallon. If you only need propane for a water heater, cooking, or a fireplace on a smaller property, the 250 or 325 gallon propane tank sizes are appropriate. See how long each size lasts.
