Gas canister stoves are a popular choice for backpackers and campers due to their convenience, efficiency, and ease of use[1].

These stoves typically use canisters filled with a mix of propane, n-butane, and/or isobutane gas, selling in common sizes like 450g, 227g, and 110g[1]. The fuel blend matters when camping in cold conditions: for temperatures below 10°C, avoid pure butane blends as they do not vaporize well; propane blends are better for cold weather performance[1].

Gas in these canisters is stored in a liquid state due to pressure. When the stove valve is opened, the pressure drops, causing the liquid to vaporize and form a flammable gas mixture at the burner[1]. This process relies on the outside temperature being higher than the boiling point of the liquid gas, which can cause performance issues in extremely cold conditions[1].

There are several types of gas canister stoves:

  • Upright canister stoves – The lightest and simplest, ranging from 35g-190g. They screw directly onto the canister, have fold-out supports for pots, and are favored for their compact design. Brands include MSR, Soto, Optimus, BRS, and Kovea[1].
  • Integrated canister systems – Feature a burner screwed onto the canister, paired with a dedicated pot and lid. These systems excel at boiling water quickly and usually include built-in windscreens and pressure regulators for consistent performance in cold and high-altitude conditions. However, they are heavier and more prone to tipping over[3].
  • Remote canister stoves – Sit separately from the canister, connected by a hose. They offer increased stability, especially for larger pots, and cold weather performance can be improved by inverting the canister. They are generally lightweight but bulkier than upright stoves[3].

Safety considerations are crucial when using gas canister stoves:

  • Always ensure both the stove and canister carry the proper safety certification (e.g., SAFETY Mark)[2].
  • Use in a well-ventilated area and do not trap heat around the stove[2].
  • Never use oversized pans that can direct heat back to the canister; this can cause overheating and explosions[2].
  • Follow manufacturer recommendations for operating time and maintenance[2].
  • Remove the canister after use, cap the valve, and store in a cool place away from fires, even if empty[2].
  • Do not attempt to repair the stove yourself or use a damaged stove[2].
  • Be vigilant for gas leaks; if detected, extinguish all flames and shut off all valves immediately[2].

Major risks include:

  • Burns (from hot water, food, stove, or flame), especially if the setup is unstable or the area is cluttered[4].
  • Canister explosions, typically caused by overheating, incorrect attachment, or using cheap/faulty appliances[4].
  • Carbon monoxide poisoning, commonly due to improper stove usage in enclosed or poorly ventilated areas[4].

Popular gas canister stove models praised for their reliability and value include the MSR Pocket Rocket and the budget-friendly BRS-3000T[5].
