Are propane or butane torches best? 

Gas torches, both propane and butane, are important tools for people from all walks of life and in various industries. Chefs and tradesmen will find a use for these tools at some point, but non-professionals and homemakers are unlikely to know the differences between the two. Propane and butane torches have their pros and cons and only one of them is the best choice for everyday use.

General similarities and differences

From a usability standpoint, the primary difference between propane and butane torches is their size. Propane torches are much larger to compensate for higher and faster heat, while butane torches are less bulky. Propane tanks often require the use of both hands, one to direct the torch head and the other to hold the cylinder, while a butane torch is a single-hand tool.

If you’re concerned about the environment, you should know that both propane and butane torches are non-toxic and have a relatively clean burn. They have no long-term negative effects on the environment and are safe to use, as long as they are used correctly.

Butane torch

Butane torches are ideal for simple home improvement and cooking projects. They can meld metals and wiring, loosen stuck mechanical fasteners and fix plumbing issues. This torch burns at approximately 2,610 degrees. These torches usually cost between $15-$20 at Amazon.

Butane torch pros

Butane torches give off less carbon monoxide when they burn, having a smaller flame in comparison to a propane torch. A butane torch has a high enough temperature to melt most common metals, such as aluminum and copper, making it a great tool for home repairs. 

The compact and portable shape of the bottle makes it most useful for cooking endeavors. A butane torch can be used to caramelize sugar, brown toppings, char entrees and create flaming cocktails. Tobacco enthusiasts use pocket butane torches as a convenient tool for lighting larger cigars. 

Butane torch cons

While they may give off less harmful gases and be useful in everyday ventures, butane cannot be used in freezing temperatures (30 degrees and below). Butane’s slow burn is nowhere near as high and powerful as a propane torch.

Propane torch

Propane torches are best for home improvement projects of a larger scale. These are popular tools in construction, manufacturing, and metalworking industries, being best utilized for welding and soldering metals. Although they can be used in large-scale industry projects, propane torches are also tools that can be used in the kitchen, much like butane, but with ventilation restrictions.

Depending on the type of propane torch, it may be able to reach temperatures of over 3,600 degrees. Propane torches cost the same as butane, between $15-$20 at Amazon and Home Depot.

Propane torch pros

With the higher heat and faster burn, propane torches work much faster than butane torches. They can do basic plumbing jobs and are inexpensive options compared to higher-heat alternatives.  Propane has a boiling point of -43 degrees which means that it can work in below-freezing temperatures, unlike butane.

While butane is typically preferred as an indoor cooking torch, propane is the better choice for outdoor grilling. In the winter, butane will not be operable under certain conditions, making propane the obvious choice.

Propane torch cons

Propane burns hotter than butane, with the price of giving off more carbon monoxide. You should never use a propane torch inside unless there is proper ventilation.  Propane torches have a bigger tank, making them less portable than butane torches.

Should you get a butane or propane torch?

Considering the two torches and their use, a butane torch is a more reasonable purchase for basic home projects. It is a more compact device and can be used for both cooking and plumbing. Unless you live in a very cold area year-round or are searching for an outdoor grilling tool, a butane torch is a more practical purchase.
