Gas burners are devices that differ in design and in areas of applicability, but they have one thing in common - they operate on gas. Gas canister burners with piezo ignition are compact products that provide adjustment of the shape, power and temperature of the flame. These portable, refillable designs, powered by a small-volume tube filled with a gas composition, should not be confused with larger, industrial welding machines powered by bulk cylinders of natural gas.
Using a small burner, you can quickly light a barbecue, heat metal construction elements in the cold, or melt plastic parts.
The fire temperature (up to +1300°C) is quite enough for soldering metal structures.
A burner flame is often required at home, during hikes, and for light installation operations. In this context, their tourist use is especially popular, for example, for starting a fire or heating canned food.
The burners are designed so that they do not clog, do not require heating, and do not accumulate odors. Possessing extensive functionality, they have a very wide range of applications.
Structurally, these devices are different - from elementary products to complex mechanisms equipped with special air ducts and piezoelements. There are several types:
- portable stoves;
- tabletop stoves;
- burners.
The first are devices that include a cartridge with a gas composition, a special nozzle attached directly to the gas container or using adapter hoses.
The peculiarity of the top of the device is that containers of certain sizes can be installed on it.
The second are units with a spacious, horizontally located cooking part. The can is installed in the housing, where it is secured with a collet grip. Such products also provide for connection to conventional cylinders using special adapters and adapters.
The third type of product is produced in the form of nozzles put on a can, or mini-burners with built-in small gas containers.
The simplest design can be described as follows: a gas jet divider with a power regulator is attached to a gas cartridge, which also acts as a stand. At the same time, the device is compact, lightweight and inexpensive.
There are also sophisticated products that include folding supports and hoses with valves. They are larger in size and weight, but more stable.
Most of the models produced are equipped with piezo ignition, which ensures automatic ignition of the fuel. The function is convenient and practical, but to a certain extent it is quite vulnerable, requiring proper operation of the device.
Therefore, the ignition function should be duplicated.
Most household products belong to the category of injection devices, in which air is naturally sucked into the burner to maintain the fire. Inside the device, in a special chamber, fuel is mixed with air, and after a spark appears, the mixture ignites. Such injectors help increase productivity and reduce fuel consumption. Nozzles can be ring, slot or tubular.
The advantages of burners include:
- reliability and design simplicity;
- efficiency;
- ease of carrying;
- long service life;
- environmental friendliness;
- possibility of cooking food where making fires is prohibited.
Flaws:
- difficulties with disposal of cylinders;
- unreliable work in winter.
What are they?
Burners are distinguished by purpose, design, and types of fuel used. The intended purpose of burners largely determines the variety of their types and the conditions in which they are used. So, they distinguish:
- mini-burners (small);
- manual;
- portable travel;
- household;
- "pencils";
- for soldering;
- with gas control;
- infrared;
- alcohol
For example, portable units are used for:
- processing of wood products;
- devices with a “pistol” type directed flame are often used in installation types of work;
- processing of steel parts using solders;
- for making fires;
- for heating and cutting metal fragments;
- for thawing frozen pipelines.
Burners are a useful tool in auto repair shops, during the construction of greenhouses and other household structures. They are also divided according to the methods of attaching the cylinders. Several such types are known:
- on thread;
- collet - put on and turn a little;
- valves - on clamps;
- pierceable - connection with soft pressure.
Most often, threaded connections are used - they are reliable. Punctureable - do not turn off until the gas in the cartridge runs out.
The disadvantage of collet connections is that the fastener quickly becomes loose, leading to gas leaks. Valve types are more reliable.
Manufacturers use various types of flammable substances to inflate cartridges. The final selection of flammable substance is based on the intended use of the products, the required fire temperature, and power. To improve the composition parameters, several types of fuel are often mixed. The most commonly used combinations are:
- propane-butane (70: 30) - mainly for use in summer;
- propane, butane and isobutane in various combinations;
- MAPP – methyl acetylene propadiene (for welding).
Cartridges are often produced that are filled with some homogeneous substance. Fuel selection is especially important when work is planned in extreme weather conditions.
Tips for choosing the best burner
People buy compact hand burners with pleasure, as they have many advantages over liquid fuel, more “serious” devices. They light quickly, hardly get dirty, and require a minimum of care.
Using a manual model is easy: the flame power can be adjusted and the torch can be directed at any angle, which is important when working in cramped conditions

The best petrol camping burners
Optimus Nova+
The old Swedish company traditionally does not upset us (well, if you don’t look at the price tag, of course) - the famous Nova expeditionary burner is convenient, powerful (2.85 kW), reliable and capable of operating on any fuel: even aviation kerosene and diesel fuel. No, really, the manufacturer writes directly about this. The trick is in the absence of an evaporator as such, that is, it simply physically cannot become clogged with soot from low-quality fuel. And if the nozzle gets clogged, you can clean it without even interrupting cooking, just open the fire to maximum and use the magnet built into the included multitool to move the needle inside the nozzle.
Unlike the well-known Nova, Nova+ is now regulated by a valve located at the remote reservoir itself, rather than by a regulator on the burner. This is definitely more convenient, although the burner was already as close to ideal as possible. If you use additional wind protection, there will be no difficulties with adjustment, because nothing will interfere with access to the regulator. The burner itself has become more compact and lighter, although not by much.
The equipment is also enviable - in addition to the burner itself, there is not only a set of spare parts and a multi-tool for maintenance, but even a tube of lubricant for the pump. All this is laid out in the pockets of the branded case. Attaching the hose to the fuel tank is a quick release; you don’t have to screw the thread back and forth.
Unfortunately, some online stores indicate that it can also work on gas, although this is not at all true: obviously, someone translated white gas crookedly from the instructions. This, naturally, is not gas at all, but pure straight-run gasoline (gas - short for gasoline) without additives, which is used as a solvent and just as fuel for burners - a kind of English-language analogue of our “Galoshes”. Take this point into account when choosing, so as not to rack your brains later about how to screw a gas cylinder here.
Main advantages:
- Reference Reliability
- Excellent equipment
- Unpretentiousness to fuel
- Easy to clean the nozzle with light contamination - you don’t even have to extinguish it
Minuses:
- High price
9.9 / 10Rating Reviews One of the most famous tourist burners in the world, whatever one may say: expensive, but really high quality and reliable. Read more Read more
Coleman Feather 442-700E
The American company Coleman, which began producing table lamps more than a hundred years ago, has now become one of the most famous manufacturers of tourism products - from folding furniture and tents to, in fact, burners. Their Feather gasoline burner is simple and reliable - the pump is protected from pumping, is easy to maintain, the tank does not heat up during long-term operation of the burner (and this is precisely why the most dangerous problems usually begin with gasoline stoves of the classical design).
Precautions for use
A hot water burner, like any tool that produces a flame during operation, is a high-risk tool.
Therefore, when using it, you must follow a number of rules that will help protect yourself and others, as well as carry out the planned processes efficiently:
- regularly carry out a preliminary inspection of the structure, make sure that the equipment is in good condition and that there is no risk of gas leakage due to a damaged hose or connections;
- when igniting gas, do not stand in front of the nozzle, do not direct the fire towards the gas cylinder, hoses, or people;
- in the process of fusing various materials, carefully control the flame, avoid excessive heating and accidental fires;
- do not go beyond the working area with the device;
- Do not work near gas cylinders or gas pipelines - the safe distance is at least 10 meters.
Fire extinguishers and sandboxes should be present at the workplace to help suppress a fire in the event of a fire. If the connecting hose or glass is clogged, the device cannot be used. This may be indicated by popping noises, kickbacks, or overheating of the equipment.
Having identified such problems, you should turn off the device by shutting off the fuel supply. Do not use wire or other sharp objects to clean the mouthpiece.
To protect your eyes from the harmful effects of infrared and ultraviolet radiation, it is advisable to use special glasses with light filters. You need to work in clean, oil-free workwear and non-slip shoes
In addition, the device must be extinguished correctly. First of all, the fuel supply is shut off, and then the lever is released.
It is not recommended to leave the tool turned on during breaks in work: it is better to extinguish the flame. If a significant break is planned, you need to shut off the gas supply to the cylinder by tightening the reducer valve.
How to choose a torch for connecting copper pipes is described in detail in the following article. We recommend that you read the useful information material. The torch soldering technology is given here, the process is outlined in great detail.
The best gas burners with piezo ignition
Kemper 1060
The Italian company has specialized in “everything that heats” since 1953, and its burners are worth a look. “One thousand sixtieth” is a lightweight and ergonomic gas burner, designed for a threaded cylinder (7/16”) and, according to the manufacturer, capable of developing a flame temperature of up to 2200 degrees. Its flame is thin, “pencil-like,” so it is ideal for work that requires precision (for example, when soldering copper pipes).
We note the build quality, a reliable piezoelectric element and good performance of the gas supply regulator. What is especially good is that there is preheating of the gas entering the burner, due to which it does not suffer from high sensitivity to the orientation of the cylinder in space. In general, it can definitely be recommended for soldering work, and the same bolts and nuts, due to the thin flame, it is very convenient - there is less chance of burning something that was not necessary. The burner is sold in two versions - on its own and with a small cylinder (Kemper 1060 Kit). It’s better to take it “naked” and buy a larger cylinder: the complete one is still too small.
Main advantages:
- Overall high quality
- Gas preheating
- Reliable gas supply regulator
Minuses:
- No adapter for collet cylinders included
- The air supply adjustment ring gets very hot during operation; you can’t turn it “on the go” without an asbestos glove
9.7 / 10 Rating Reviews Lightweight and convenient gas burner, I had already used other “Campers” before purchasing – the feelings were strictly positive.
Kovea Master KT-2211
Often in online stores this gas burner is called a “gas cutter”. Gentlemen, can you tell me where to connect her oxygen tank? However, if we talk about the burner itself, it is very good: convenient shape, economical gas consumption. Of course, for work that requires constantly turning the burner at different angles, we do not recommend it - due to the lack of gas preheating, it may begin to “spit” when liquefied butane, which does not have time to evaporate, flies out of it, but in general it is an interesting purchase option .
The flame is thin, with a good jet length. The declared temperature is up to 1300 degrees. It is designed for a collet cylinder, which can be easily and quickly replaced if necessary. Although the threaded fastening is more reliable, of course.
Main advantages:
- Good build quality
- Ease of use
- Economical consumption
Minuses:
- No gas preheating
9.5 / 10Rating Reviews Not a bad burner, I tried soldering and heating rusty fasteners - it worked fine.
MATRIX 91427
The burner is designed for inexpensive collet cylinders and produces a wide flame with an appropriate flow rate. The air supply is not adjustable, that is, we have the option of “burning with all your money”, without fine adjustment of the flame - not the most universal, but quite suitable for a number of jobs.
Another thing is that it has some problems with the reliability of the piezo element - yes, “piezos” are not particularly reliable from a purely structural point of view due to the design itself, and you can always set it on fire with a lighter... but there are more interesting options for comparable money, is not it?
Main advantages:
- Fast heating of massive parts
- Good reliability of the gas regulator
Minuses:
- Not the best piezo element resource
- No air regulator
9.2 / 10Rating Reviews I had a chance to warm up the pipes somehow, it worked without problems and quickly, so I wasn’t upset by the purchase.
Sturm! 5015-KL-01
450
But this cheap gas burner is not particularly suitable for delicate work - its flame is too “solid” for this. Accordingly, the gas in the cylinder (buy collet ones) will run out rather quickly. For ignition and heating of massive metal parts and pipes, it will be better than for “jewelry” soldering. And, in the end, the burner is quite inexpensive - this is exactly the option for one-time work that we mentioned at the very beginning. For regular use, naturally, it is worth buying a burner that is more expensive and of better quality.
Its weak point is the ignition unit, which is controlled by the same handle with the valve itself: to adjust, we turn, to ignite, we press. Separate control without such complications is more reliable and generally more convenient.
Main advantages:
- Low price
- Fairly stable flame after warming up
Minuses:
- Reliability – “for the money”
9.0 / 10Rating Reviews I bought it once, and have used it several times since then – I think it has long since paid off its penny price.
Do-it-yourself refilling of mini-burner cans
Before starting the refilling process, make sure that the cylinder does not have any remaining gas mixture. It is turned over so that the valve is at the bottom and shaken.
Refilling process for mini burner:
- Take ordinary scales and weigh the empty cylinder so that after the process is completed you can determine the exact amount of fuel mixture filled.
- Connect the container to be filled with a propane cylinder using an adapter.
- Close the valve on the adapter.
- Open the valve on the can.
- Gradually open the valve on the adapter, at this moment gas enters, squeezing the air out of the hose.
- Monitor the filling process and, after completion, disassemble the circuit in the reverse order.
- Disconnect the tourist cylinder.
- Using the shaking method, the presence of gas is determined; the liquid in the vessel should flutter, which indicates the presence of a mandatory free space, which experts call a gas cap.
- Check the valve for leaks with a soap solution. Verification by fire is strictly prohibited.
The best miniature gas burners
Dayrex 20
But they didn’t guess right! This time, the winner in the ranking of the best gas burners was not Kemper, but another manufacturer. Dayrex is more interesting in several ways – let’s start in order. Firstly, it is, albeit slightly, more capacious, and for such “pencils” this can already be felt in the operating time at one gas station. The regulator with a grooved ring is more convenient to use, and it is equipped with an additional rotary lock - “child protection”. And finally, the nozzle for soldering tips is cheaper, and in some configurations it is included directly with the torch.
Main advantages:
- Good reliability
- Ease of adjustment
Minuses:
- The regulator and fill valve will probably start to leak faster than a comparable priced Kemper - but that's far from certain.
9.8 / 10Rating Reviews Convenient and very compact burner, holds refills and is precisely adjustable.
Features of choosing a compact device
Before buying a gas burner, you need to decide on its purpose - for repairs, soldering parts, tourism, cooking. The choice of model depends on the tasks that the device will have to cope with. And here it is important to understand the differences between burner types.
Varieties of popular devices
There are 4 main designs: “lighters” screwed onto a cylinder, with a fuel hose, blowtorches. There are also integrated cooking systems, but they are difficult to classify as mini. These devices are large in size and weight, expensive, and can only be used with original cookware.
Type #1 - portable torch lighter
The smallest “lighters” are convenient for household purposes and minor repairs. Some models produce more power and can be used for soldering.
A miniature gas burner similar to a lighter, depending on the model, can have very impressive indicators in terms of power and temperature of the flame produced
Type #2 - balloon type mini-burner
Compact cylinder burners are convenient and light in weight - most devices fit in your hand and fall in the weight range of 70-90 g. They are easy to use, inexpensive, and relatively reliable.
It is not recommended to install a continuous wind shield around the cylinder so that the reflected heat does not lead to an explosion of the fuel mixture
The cylinder itself cannot be forcibly heated, so such burners are not entirely suitable for use in difficult weather conditions.
Another nuance is that the lightness of the design does not allow you to place large-capacity dishes (from 3 liters) on it. But for some models branded adapters are sold: hoses, additional legs.
The rating of the best gas burners for a can is presented in this review.
Type #3 - device with remote hose
But devices with a hose perform well in bad weather conditions. You can place bulky or heavy dishes on them. Fuel consumption in such burners is minimal.
The cylinder can be warmed up with your hands, placed in a container with warm water, wrapped, or put in a sleeping bag or tent vestibule.
A continuous wind shield can be installed around the burner with a hose, which will increase work efficiency. The design itself is distinguished by the wide setting of the legs and squatness. The permissible volume of dishes is up to 8 liters.
Often in such devices the nozzle itself is larger than that of the bulbs. Due to this, the dishes are heated evenly, and the flame power is conveniently regulated. The burner allows you not only to heat water, but also to fry and stew food.
Devices with a hose also have their disadvantages. They are heavier and larger in size. The hose requires careful operation; the part may break and lead to a gas leak.
Type #4 - blowtorch
Portable blowtorches are designed for the application of machining connections made of ferrous and non-ferrous metals. They are found in piping systems, electrical appliances, cables, and car parts. These also include torches for soldering copper pipes.
The characteristics indicate the flame temperature and power. A device whose flame heats up to 1200-1500°C can cope with parts up to 3 mm thick. A power of 2-3 kW is enough to heat and bend reinforcement up to 14 mm.
Soldering torches are widely used for making and repairing jewelry. Designs with the ability to connect nozzles and a targeted, adjustable flame are selected
The scope of application of such devices is not limited to soldering. They do an excellent job of lighting a fire, working in a summer cottage (removing leaves, getting rid of insect colonies), wood burning, and culinary experiments.
Method of connection to the cylinder used
Most models on the market are adapted for threaded cylinders. But purchasing them in remote settlements is problematic.
If the hike will take place in such areas, you need to very accurately calculate the required amount of gas or additionally buy an adapter for a collet one.
In terms of consumption, a threaded cylinder lasts for a longer time due to the different composition of the gas mixture and the strength of the shell. More pressure gives more heat transfer
Collet cylinders are also called “dichlorphos”. They are sold at almost any hardware store. But the seam design is less reliable, and the gas mixture is sensitive to low temperatures.
Burners for threaded cylinders are cheaper, but the cylinder itself costs 3-4 times more than a collet one. But if you choose cylinders based on gas composition, the cost will be approximately the same
There is also a third type of cylinders on the Russian market - without threads with a bayonet mount. But they are represented only by the Campingaz and are not as widespread as abroad.
There are models adapted for use in conjunction with a threaded and bayonet standard.
Additional device options
The presence of piezo ignition is a useful addition, but it is still worth having a backup fire source with you. For some models, this element quickly becomes unusable.
Wind protection for the burner in the field can be built from available means: a depression in the ground, stones, improvised fence walls
If your camping burner is missing a grate, a protective cover on your computer fan can easily replace it. It is lightweight and does the job perfectly.
When choosing a device for delicate work, welding, soldering, you should pay attention to the ergonomics and balancing of the model. The shape of the body and the arrangement of the elements matter, because the burner will have to be turned on and off frequently. It is convenient if this can be done with one hand.
