Bulk delivery vs cylinder exchange
Two distinct supply models cover all US residential propane:
- Bulk delivery: truck delivers liquid propane to a permanent tank on your property. Standard for heating households (200+ gal/year usage).
- Cylinder exchange / refill: 20 lb or 100 lb portable cylinders swapped at retail (Blue Rhino, AmeriGas Cylinder Exchange) or refilled at local dispensaries. Standard for grills, RVs, small users.
When bulk makes sense
Bulk delivery to a permanent tank is the right choice when:
- You use propane for space heating (the dominant heating-household pattern)
- Annual consumption is over ~250 gallons (cylinder economics break down at this volume)
- You have outdoor space for an installed tank meeting NFPA 58 setbacks
- You're committed to a 1-year-plus relationship with a propane dealer
When cylinders make sense
Cylinder propane fits when:
- Use is limited to grills, patio heaters, or occasional applications
- You're in a rental or short-term housing situation
- Lot configuration doesn't accommodate a permanent tank
- Annual consumption is under ~100 gallons
Bulk delivery logistics
Standard bulk delivery: truck pulls up to the property, driver connects hose to your tank's fill valve, pumps propane to 80% level, records the volume, leaves a receipt. Typical delivery takes 10–20 minutes. See filling a propane tank.
FAQ
Can I refill my own 20-lb cylinder?
Some propane retailers and U-Haul locations offer cylinder refill at typically lower cost per gallon than exchange (you keep your own cylinder rather than swapping for one with less propane). DOT recertification rules still apply — your cylinder must be within its certification window.
What's the price difference between bulk and cylinder propane?
Cylinder exchange is much more expensive per gallon — typical 20 lb (4.7 gal) exchange runs $25–$35, equivalent to $5–$7 per gallon vs $2.40–$3.20 for bulk delivery. The exchange premium covers cylinder handling and retail convenience.
