How Hot Does Propane Burn?
Some Helpful Information About the Fuel
Propane has an adiabatic flame temperature of roughly 3,560°F under ideal conditions. That high combustion temperature helps make propane a useful fuel for applications such as home heating, water heating, cooking, and commercial equipment.
Propane’s energy content can also be measured in British thermal units, or Btus. One Btu is the amount of energy required to raise the temperature of one pound of water by 1°F.
One gallon of propane contains about 91,500 Btus of energy. Electricity is measured differently: one kilowatt-hour of electricity is equivalent to about 3,412 Btus. Because the units are different, these figures should not be compared as though one gallon of propane and one kilowatt-hour of electricity were equal quantities.

More Helpful Facts About Propane
- A properly operating propane burner usually has a blue flame: A persistent yellow or orange flame can indicate a combustion problem and should be checked by a qualified professional. Incomplete combustion can increase the risk of carbon monoxide production.
- Propane comes from natural gas processing and petroleum refining: It is commonly classified as liquefied petroleum gas, or LPG.
- Propane does not spoil: Unlike some fuels, propane does not degrade over time when it is properly stored in a suitable tank.
- Propane does not contaminate soil or groundwater like a liquid fuel spill can: Propane is stored as a liquid under pressure but vaporizes when released into the atmosphere.
- Propane is naturally colorless and odorless: An odorant is added so leaks can be detected by their distinctive rotten-egg smell. If you smell propane, leave the area and contact your propane provider or emergency services from a safe location.
- Propane is widely produced in the United States: Domestic production helps make it readily available for residential, commercial, agricultural, and industrial use.
- Propane is highly versatile: It can be used for water heating, home heating, pool and spa heating, cooking, fireplaces, forklifts, outdoor equipment, and standby generators.
- Propane contains substantial energy in a compact volume: Compared with natural gas on a volume basis, propane contains considerably more energy per cubic foot. Actual appliance performance depends on equipment design and efficiency.
- Propane expands as its temperature rises: For this reason, propane tanks are not filled completely. Leaving vapor space in the tank allows the liquid propane room to expand safely as temperatures change.
