The Difference Between Butane and Propane

Use Scenarios for Propane

Propane torches are highly versatile and can be used in a wide range of settings at various levels of heat.

• Plumbing and Soldering: Propane’s high heat makes it ideal for joining pipes or repairing metal surfaces in basic plumbing repairs.
• Outdoor Cooking and Grilling: Propane performs well in colder temperatures and can be used for outdoor cooking projects like grills or camp stoves.
• Automotive Repairs: It’s often used to loosen rusted bolts or parts in car repairs.
• Metalwork and Welding: The intense flame temperature is suitable for brazing, welding, and other heavy-duty metalwork.
• Roofing and Asphalt Work: Propane torches are used in large-scale roofing projects to melt tar or asphalt.

Use Scenarios for Butane

Butane models are better suited for precision tasks where a smaller, controlled flame is needed.

• Culinary Use: The clean burn makes it popular for catering trays or table-side cooking. Butane mini torches are a convenient tool for creating a caramelized sugar crust or is often the preferred choice for caramelizing sugar on crème brûlée or searing delicate foods.
• Jewelry Making: Its manageable flame is great for soldering small common metal pieces without overheating.
• Laboratory Applications: Butane torches are often used in labs for heating small items or performing scientific experiments.
• Portable Camping Stoves: Butane’s compact canisters make it ideal for lightweight camping trips, particularly in mild weather.
• Lighters: Butane lighters are frequently used in all sorts of hobbies like lighting incense, arts and crafts, or recreational use.

Which torch is safer for indoor use?

Many indoor stoves use propane as it can be stored outdoors in large volumes at cold temperatures. But, butane models are generally safer for indoor use because produces less carbon monoxide. Either way, it's important to have good ventilation to disperse the emissions (carbon dioxide, carbon monoxide) even when using something small like a heat gun or mini butane torch.

Can I put propane in a butane blow torch?

No, absolutely not. Propane and butane require different torch mechanisms due to their differing pressure and combustion properties. A butane torch model is not designed to hold the amount of pressure that propane exerts. Attempting to use propane in a butane model could damage the torch head or even cause an explosion.

Conversely, you shouldn't put butane fluid in a propane tank either. The pressure of butane gas won't release from a propane torch head at the proper velocity and the slow leak can cause an unpredictable flame size and fire risk.

What torch burns hotter, propane or butane?

Both of these gases produce blue flames, but propane has a much hotter flame up to 3,600°F (1,982°C). Butane has a direct heat output of approximately 2,400°F (1,316°C). This makes propane more suitable for tasks like welding and metalwork. Butane's lower flame temperature is better for precision tasks like culinary applications or jewelry-making.
