Portable gas stove with a canister box: design, pros and cons, and who should use one

Most familiar portable gas stoves have a canister compartment right at the side, next to the burner. A portable gas stove with a canister box is different: the canister sits in a separate box, connected to the cooktop by a hose. Below are its design, pros and cons, who it suits and the specific points to check.

What is a portable gas stove with a canister box?

The stove has three parts: the cooktop (burner, pot support, flame control knob and, depending on the model, an igniter), the canister box (where the canister is fitted, with a coupling to the canister valve) and the hose connecting the box to the cooktop. When cooking, the cooktop sits in the middle of the table, while the canister box is placed off to one side, a hose length away from the burner. Two VietnhatGas models of this type are the VNG001 portable gas stove and the VNG/BG003.

How does it differ from a side-loading stove?

On a side-loading stove, the canister sits next to the burner, separated only by a heat shield, so oversized pots or trays can easily reflect heat down onto the canister — a risk discussed in our article on how to use a portable gas stove safely. The canister box design changes precisely where the canister sits.

Advantages of the canister box design

• The canister is further from the heat: the pot area is not next to the canister, reducing the risk of the canister being warmed during long cooking. Even so, do not use grill trays that cover the whole cooktop.
• Flexible layout: the canister box goes on the staff side of the table, away from where guests sit; the small cooktop fits neatly in the middle of the table.
• Convenient canister changes: after turning the stove off, staff open the box and change the canister without lifting the hotpot.

Disadvantages to know before buying

• More points where gas could leak: the hose and its two joints.
• The hose is easily affected: it can be kinked, crushed, caught by passers-by’s feet or pulled taut when the stove is moved.
• Bulkier: two units plus a length of hose need more storage space.
• Dedicated parts: the hose and seals must be the manufacturer’s correct type, so buy from a seller that supports replacements.

Who should choose this type of stove?

• Hotpot and table-grill restaurants: stoves run for many hours and canisters are changed often. To work out the number of stoves and canisters, see our article on butane for hotpot restaurants.
• Less suitable for trips where you need to travel as light as possible — see portable gas stoves for picnics and camping.

General criteria such as output, flame control and materials are covered in our guide to choosing a portable gas stove.

Specific checks for the hose and canister box

1. Look along the hose before each use: no kinks, twists, flattening, scorching or cracks. Signs of a damaged hose are similar to those on a gas cylinder hose — see when to replace a gas hose.
2. Check both joints: firm, not loose. Do not remove the hose yourself, extend it or replace it with a different type of hose.
3. Check the canister box: no dents and no foreign objects inside; fit the canister into the correct notch as instructed.
4. Lay the hose with a little slack, not across walkways, not under the base of a pot or near other heat sources.
5. Suspected leak at a joint: turn the knob off, remove the canister and test with soapy water; never use a flame. If you smell gas: ventilate, do not switch electrical equipment on or off and stop using the stove.
6. After cooking: turn the stove off, wait for it to cool, remove the canister from the box and coil the hose loosely before putting it away.
