Where To Buy Iwatani Butane?

Is it possible to use different brands of butane in my Iwatani stove or torch? To ensure maximum performance and customer safety, all Iwatani butane products must be used with Iwatani brand fuel.

Where are Iwatani stoves made?

The ZA-3HP includes an aluminum burner, a removable drip tray (made of painted or anodized metal), and four aluminum tabs that form a grate to hold your pan slightly above the burner. A unique strip of metal connects the burner to the butane canister holder, allowing part of the heat from the flame to be channeled back to the canister. The notion is that as a depleting canister flows less and less gas, it will become colder and colder, thus you want to keep it warm by using waste heat. This ensures a constant flame regardless of how low the canister gets.

  • To reveal the canister holder, lift open the tiny metal gate on the right side.
  • Insert one 8-oz. (227g) butane canister/cassette, match the notch in the canister’s rim with the tab in the burner’s locking mechanism, then press the black lever on the front panel down to lock the canister into place.
  • Turn the black dial all the way to the left until the igniter “clicks.”
  • If you want less power, turn the black dial to the right; if you don’t want the flame to die out, follow the power guide painted next to the knob and stay at or above “simmer.”
  • Turn the black dial to “off,” open the canister holder’s lid, then push the front panel’s lever up to release the canister for disposal when you’re finished.
  • You can get a few hours or so out of each butane burner depending on how high you set it.

The flame circle’s diameter varies based on the form of the pan. I’d feel at ease cooking in anything up to a 12 inch frying pan or 11 inch saute–possibly even larger if you have a pan that heats evenly.

You can get a few hours or so out of each butane burner depending on how high you set it.

(If you live in a rental and can’t replace your electric coil stove, you may complement it with an Iwatani burner for brief cooking tasks and only pay a few dollars per month for butane.) To save money on butane, utilize the electric coil for long boils, simmers, and braises.)

Despite the fact that the unit is rated at 12,000 Btu/h, it turns out that this is contingent on a number of factors:


  • A new Iwatani butane canister was used. Over time, an aged canister will produce less. In addition, lower-quality butane canisters won’t produce as much heat.
  • I’m cooking on a brand new Iwatani ZA-3HP stove.
  • The butane stove’s piping will become slightly clogged with age, and output will drop by a few percent.
  • Although the burner produces 10,000 Btu/h, Iwatani states that the aluminum heating connector makes the system more efficient by preventing the can from dropping too low in temperature, resulting in the burner producing as if it were a 12,000 Btu/h burner.

If you’re interested in the Iwatani 35-FW, the big brother of the ZA-3HP butane stove, the 35-FW is built in Japan and has brass parts, a larger grate, 15,000 Btuh/h output (that’s 25% more heat than the ZA-3HP), and a small windshield, but it costs twice as much. The larger heat output and windshield make it ideal for car camping, and the better component quality ensures unit longevity. The 35-FW has a more advanced magnetic locking system, but the ZA-3HP lever locking method is quite adequate.

(Note: Most cheap natural gas stoves, such as those found in many apartment rental units, have a maximum output of 9,000 Btu/h on the largest burner.)

The largest burner on a high-end domestic stove can produce at least 17,000 Btu/h.

As a result, the ZA-3HP’s 12,000 Btu/h is comparable to a medium-priced household natural gas cooktop’s largest burner.)

This butane stove, the ZA-3HP, is almost ideal. The worst thing I can say about this unit is that there are times when you turn the dial too fast when starting it up and there isn’t enough gas for the igniter to fire, so you have to crank it back down and try again. So, every now and then, you squander an extra three seconds of fuel.

I heartily recommend the Iwatani ZA-3HP Portable Butane Stove Burner if you want a relatively inexpensive, portable gas burner that was designed and made by a Japanese firm (rather than some dubious Chinese company).

I trust it not to blow up in my face, and I’ve used it in a variety of situations.

The burner can be used for a variety of purposes, including:

  • During a power outage, prepare meals, including warming infant formula. (Be careful holding small bottles or other items above the burner; even at low power, it gets incredibly hot even six inches above the burner’s surface.)
  • Cooking outside is a great idea.
  • Picnics, car camping, and so on. It’s significantly more powerful, steady, and wind-resistant than backpacking stoves like the Jetboil Flash, which I own and use exclusively for backpacking. The Iwatani ZA-3HP is a more affordable option for car camping and cooks similarly to a gas stove at home.
  • Prepare the pans by seasoning them.
  • It doesn’t matter if it’s made of carbon steel or copper.
  • It does not get hot enough to set oil on fire when used for short periods of time, but it does get hot enough to burn the oil on.
  • Seasoning pans, on the other hand, creates harmful smoke, so do so outside and hold your breath if you get too close to the burner.
  • Cook with cookware that isn’t induction compatible.
  • Its quick heat outperforms cheap electric coil stoves.
  • Prepare a “bug out bag” or a survivalist/earthquake/natural disaster pack in case of an emergency.
  • Boiling water kills disease-causing germs in addition to allowing you to cook food.
  • When exposed to high temperatures, such as those found on the bottom of a frying pan during frying, most microorganisms die.

Note: Although Iwatani recommends using only Iwatani-branded butane canisters to ensure the 12,000 Btu rating and clean gas that won’t clog the pipework, any reputable brand of compatible 8-ounce (227 gram net weight) canisters, such as GasOne’s butane canisters, will suffice. You are not locked in and have the option to swap canister brands at any time.

Consider acquiring the grill adapter, which works with both the 12,000 and 15,000 Btu Iwatani burners if you wish to grill. Iwatani also offers a rectangular portable gas grill, however because the shapes don’t match, it doesn’t work well with circular pots and pans.

Can butane canisters explode?

Butane gas canisters are a fantastic way to fuel a stove or heating equipment while camping because they are inexpensive, easy to use, and lightweight. Gas canisters can build up pressure and explode if handled or stored incorrectly.

How long does a backpacking stove canister last?

When employing a range of heat settings, an 8 ounce canister of fuel can burn for around three hours, according to Eastern Slopes. If you plan on boiling water on high all of the time, the fuel canister will not last nearly as long. This might give you an indication of how long your canister fuel will last as a camp cook, depending on how long you expect to cook each day each meal.

Do butane canisters expire?

I discovered a can of stove fuel while rummaging through my cellar. Is this the same as conventional gasoline in terms of deterioration? —Don Turcotte of Dayville, Connecticut

They won’t go bad if you’re talking about sealed butane-mix canisters. It’s a different matter if you’re talking about a jug of white gas. White gas should be used within a few months of being opened.

We need to talk about chemistry to understand why. (Don’t worry; we’ll keep things straightforward.) White gas, like the gasoline you put in your automobile, is mostly made up of a variety of hydrocarbons—compounds made up of the atoms carbon and hydrogen. Because these hydrocarbons are so combustible, they’re perfect for fueling your stove. Unfortunately, many of them rapidly react with oxygen when exposed to air, leaving behind stale, thicker fuel that might block your stove’s lines and burners. So, while an unopened can of gasoline can be stored for years, once the seal is broken, its shelf life is drastically reduced.

On more than one occasion, I’ve used the extremely old dregs of rusty cans left in my garage. It works, but it clogs up your stove considerably more quickly, necessitating more frequent cleaning and upkeep. Bottom line: if you respect your stove and your time (since dissecting and cleaning your stove takes time), get rid of the old bottle and invest in a new one (you can get a gallon for about 5 bucks at discount chains).

However, it raises the question of what to do with the old items. It’s very combustible and hazardous, and it’s not something you want to pour down your drains, into your bed of pansies, or into the Grand Canyon. I know a lot of people who just pour it into their car’s gasoline tank. It shouldn’t cause any problems as long as there’s plenty of gas in the tank to mix it with. (I’m not advising you to do this, so don’t blame me if your car breaks down.) Bring it to a gas station or your local department of public works, both of which should have tanks into which you can empty your can.

It’s much easier to get rid of a number of old, almost-empty canisters—the green Coleman ones or the lightweight ones made for us on hiking trips—if your problem is that you have a bunch of them. Simply repurpose them: The majority of fuel canisters are made of steel and can be recycled alongside Dr. Pepper cans. Before recycling, burn up any remaining fuel (now is a great time to test that difficult camp recipe you’ve been dying to try) and puncture the empty canisters. (We use a heavy rock to crush the spent canisters.) You may just dump empty, punctured canisters into your recycle bin in Boulder, Burlington, and other environmentally concerned cities. Inquire about the rules in your area by calling your local Public Works Department.

How do I turn on my Iwatani stove?

1. Remove the cartridge’s red cap. Right next to the stove, open the flap. Align the cartridge with the BIG ARROW and notch it to the flat steel on the stove. Turn the left lever to the ON position. The cartridge will travel forward into the rod.

2. Make a U-turn firmly switch to the left all the way down until you hear a CLICK. The flame is ignited and started as a result of this. When you’re done cooking, close the flap.

3. Preheat your wok on high heat, but use this switch to adjust the flame height. When you’ve finished cooking,

Is butane a gas?

Butane is a highly flammable, colorless, odourless, and easily liquefied hydrocarbon. It is commonly used as a fuel for cigarette lighters and portable stoves, as well as a propellant in aerosols, a heating fuel, a refrigerant, and in the manufacturing of a variety of items. Liquefied Petroleum Gas (LPG) also contains butane (LPG).

Hydrocarbons have been utilized to replace chlorofluorocarbons (CFCs) as the propellant in most aerosols since 1987. Butane is a common propellant in home and industrial aerosols, therefore it can be found in a wide range of aerosol products. However, many aerosol goods’ packaging will list the propellant as ‘hydrocarbon,’ rather than directly mentioning butane.

Where is the best place to store butane?

We provide emergency preparedness training to a wide range of people. “Where is the safest place to keep gasoline (or diesel, kerosene, Coleman fuel, butane, propane, or alcohol) for an emergency?” is one of the most often requested questions. The answer is… it is debatable. The answer varies depending on the type of fuel used and where you live.

You have a lot more possibilities if you live on a 10-acre farm than if you live in a one-bedroom apartment. The issue is that gasoline is essential for everyone’s survival. You’ll need it to boil water, cook your food, maintain communications, and avoid dying from frostbite. Let’s take each of these sources of energy one by one.

When it comes to carefully storing fuel, don’t believe everything you read on the internet. Make sure you do your own research to make sure your knowledge is correct. Improper fuel storage could lead to poor fuel performance at best, and death and property loss at worst. Don’t take a chance!

Safety Data Sheets Provide Accurate Information

Studying the Safety Data Sheet for each fuel is one of the greatest ways to find correct information on it. This is the most up-to-date information available, as it comes directly from the manufacturer. For each of the fuels we discuss, I’ve included a link to an SDS sheet.

A detached shed is the safest place to store gasoline in general. Let’s look at the exact storage needs and circumstances for each of these fuels, as well as some potential storage places.

Best Way to Store Gasoline

The safest location to keep fuel is in your car’s tank. We recommend that you keep your tank at least halfway full at all times. One-half tank of gasoline should be enough to get you out of immediate danger if you need to flee.

Gasoline is a hazardous fuel to keep on hand. It should be kept in an appropriate red container in a cold, well-ventilated environment. Unapproved containers may disintegrate, releasing volatile gasoline liquid and fumes. It is critical to utilize only certified gasoline canisters. Make sure the containers are securely closed and labeled.

Our prepper friend allowed us to look into his fuel storage system and has given us permission to share it with you as long as we don’t expose his name or location. It’s simple to accomplish. Let’s refer to him as Bob.

Bob wishes to stockpile enough gasoline to be able to flee to a location 800 miles away in the event of a disaster. He has a gasoline generator that must be capable of running for at least 48 hours. His goal is to always keep 50 gallons of gasoline on hand.

Bob is well aware that storing this much gasoline in his garage or anyplace near his house is exceedingly hazardous. He makes the conscious decision not to do stupid things. When gasoline is not exposed to extremes of temperature, it stores well. He found a secondhand chest freezer and buried it in a shady spot distant from his house to solve his gasoline storage problem.

The next issue that needed to be solved was ventilation. To enable cross ventilation through the freezer, he drilled two holes to fit 2-inch vent pipes (lower front on one end and upper back on the other). To keep the vents dry and prevent vermin from getting in, they are screened and elbowed down.

The gas cans are kept off the freezer floor on custom pallets, which allows for better ventilation. The gasoline is kept in certified 5-gallon gas cans in an underground freezer. To assist insulate the contents from temperature variations and provide some operational security, the freezer is maintained covered.

An above-ground gasoline storage tank is a safe choice for storing bigger amounts of gasoline. These tanks are used to refill equipment on-site in farming and commercial operations. If this alternative appeals to you, look into the rules and laws in your area.

To preserve quality, gasoline should be rotated or stabilized every 9-12 months. To extend the life of the gasoline for several years, a good fuel stabilizer should be used at least once a year. Gasoline accounts for a significant portion of the energy we consume in our daily lives. For many people, storing a fair supply of gasoline makes sense.

Best Way to Store Diesel

Many of the same storage requirements apply to diesel as they do to unleaded gasoline. It’s a flammable liquid, so keep it away from open flames, heat, ignition sources, and direct sunlight. Static discharge protection is required. Diesel can build up a static charge, which can cause a spark and serve as an ignition source.

Diesel must be kept in a cool environment. The pressure in sealed containers rises when diesel is stored in a heated atmosphere. Make sure you only keep it in certified containers, the majority of which are yellow. Close the container tightly and store it in a well-ventilated area.

When used for construction or farming, diesel is usually stored in above-ground tanks. When storing in lesser quantities, keep it in the same places you’d keep gasoline, but make sure it’s in containers that are certified for diesel fuel.

Best Way to Store Kerosene

K-1, K-2, and Klean Heat kerosene are available for purchase. Some kinds can be purchased in containers or poured similarly to gasoline.

Kerosene should be kept in a cool, well-ventilated area when not in use. It should be kept in its original containers or in blue, vented containers that have been certified. Store away from strong oxidizers. It is less fickle when it comes to storage than gasoline and diesel.

Best Way to Store Coleman Fuel or White Gas

Coleman fuel should be stored similarly to unleaded gasoline, with the exception that it should be kept in the original bottle. Keep the original containers away from heat, sparks, open flames, and oxidizing materials in a cool, well-ventilated environment.

Best Way to Store Butane Cartridges

Preppers often use butane cartridges as a source of fuel. Compressed fuel in a can could be hazardous to keep in big quantities. Over time, the can will degrade and the butane may escape. We recommend keeping the amount of canisters you have on hand to a minimum and rotating them.

The can must be kept cool and not exposed to temperatures more than 50°C/122°F. Heat, sparks, an open flame, oxidizers, and direct sunshine should all be avoided. It’s best to keep the container in a well-ventilated environment. Because butane is heavier than air, it should never be kept in basements, cellars, or other low-lying areas where vapors can collect. Do not keep in automobiles or other similar settings where excessive heat could result in an explosion.

Following one of our seminars, a woman contacted us and revealed that she had a large number of these canisters sealed in 5-gallon buckets in her garage. According to the manufacturer’s safety guidelines in the Safety Data Sheet, this strategy has two major flaws.

  • The butane canisters are not well ventilated in sealed 5-gallon buckets.
  • The temperature in most garages may fluctuate significantly, and it may go dangerously close to 50°C/122°F.

Butane canisters are similar to little bombs that are waiting for the ideal conditions to detonate. I’d keep the amount of canisters I store to no more than 8-12 and keep them in my pantry where the temperature can be controlled. While not ideal, a limited number of people in this regulated area would not make me feel uneasy.

Remember that butane canisters are not suitable for storage in basements, therefore don’t keep them in a basement food storage room.

I fell in love with our little butane stove during our 90-day Grid Down Cooking Challenge. You can learn more about these useful stoves by visiting Butane Stove: Cooking for Power Outages in a Portable and Convenient Way

Best Way to Store Propane

One of my favorite fuels for emergency preparedness is propane. We make a concerted effort to keep all of our gas tanks topped off. Propane tanks are much safer to store than liquid fuels, which is a big plus.

One-pound disposable propane containers are convenient for emergency situations, but they are not as safe to store for longer periods of time as bigger propane tanks. I would not recommend storing big quantities of disposable propane bottles. The container’s seal may deteriorate with time, allowing propane to escape into the atmosphere.

Leaks in these containers should be examined on a regular basis. Propane, like butane, will not evaporate but will concentrate in a low-lying location, posing an explosive threat.

Propane should be kept away from flames, sparks, heat, strong oxidizers, and extreme temperatures in a well-ventilated environment. When chlorine dioxide is present near propane, it can cause an explosion. Only store in approved containers, and keep the valve closed. Explosive vapors may be present in empty propane containers. Whether your propane containers are full or empty, be careful where you keep them.

Our 20-pound propane tanks are kept in a popup tent trailer away from our house. This keeps them out of the sun and protects them from the elements. Not the best option, but we’re doing the best we can with what we’ve got.

One of our students proposed keeping the 20-pound propane bottles in a 150-gallon deck box, which is commonly used for garden equipment storage. The deck box should be kept out of direct sunlight in a shaded location. Cross ventilation would be required in the deck box (large holes drilled on both sides of the box). It may be a terrific method to keep 20-pound gas bottles out of the house and protected from the elements.

Propane, rather than gasoline or diesel fuel, is a superior alternative for garage storage. However, keeping huge volumes of fuel in a garage should always be avoided.

Best Way to Store Alcohol

Because it is not explosive like many other fuels, alcohol is an excellent storing fuel. Simple storage precautions are recommended. Keep the container well covered and away from sparks, open flames, and strong oxidizing agents. It’s best to keep alcohol in its original container.

The shelf life of alcohol is limitless. In our basement storage area with our food storage, we keep a reasonable amount of Everclear, SafeHeat, and denatured alcohol. That way, it’ll be ready to use whenever we need it. Only alcohol is a fuel I’d feel safe storing in my basement alongside food. When utilized as a prepper fuel, the fact that it never goes bad is a huge plus. Always keep the amount of fuel you store indoors or in your garage, including alcohol, to a minimum.

Unless you reside in a climate with extreme temperature variations, you may be able to securely keep denatured alcohol in your garage, according to the Safety Data Sheet. Storage requirements for alcohol are far more flexible than those for other fuels.

Because it creates very little, if any, carbon monoxide when burned, alcohol is an excellent choice for cooking and heating indoors. Learn more about alcohol as a fuel source in our piece, Best Alcohol Cooking Fuels for Campers and Preppers.

Best Storage Locations for Fuels

Any fuel should be stored in a detached, insulated shed that is sheltered from direct sunlight and temperature extremes on both ends. Stability of temperature is ideal. Never store gasoline in a structure you can’t afford to lose if it burns down.

Fuel is essential for survival, yet most of us must make do with what we have because we do not live in an optimum climate for fuel storage. When storing fuel, safety must be a major priority. If you store fuel incorrectly, your homeowner’s insurance policy may be voided if you have a fire. Check with your insurance agent to be sure you’re adhering to your policy’s restrictions.

In the event of a fire, a flammable storage cabinet is an excellent way to store fuel and keep it confined. The storage cabinets have self-closing hinges and are ventilated. These metal cabinets are costly, but they allow you to properly store fuels in your garage. To avoid static build-up, it’s critical to ground storage cabinets.

Always store fuel in containers intended particularly for that fuel and follow all storage recommendations on the Safety Data Sheet from the manufacturer.

Legal Restrictions and Common-Sense Practices

We highly advise you to observe all applicable legal standards and use common sense when storing your fuel. Depending on where you live, there will be different legal restrictions on gasoline storage. Your local fire department will be the finest source of factual information for your area. Our post Safe Emergency Fuel Storage Guidelines contains an example of legal guidelines.

Fuels are hazardous and must be treated with caution. Always keep in mind the people who may be affected by the fuels you store. Make them the most important thing in your life.

How Much Fuel Do I Need to Store for Emergencies?

How much fuel do you need to keep on hand in case of an emergency? That is debatable. What are you getting ready for? How long do you think you’ll be without access to public services?

The photo depicts a large backup generator for a local public utility, complete with diesel fuel tanks. In most cases, you won’t require something that outstanding to meet your demands in an emergency. If money isn’t an issue, you may put in fantastic backup solutions for your home. The majority of us are just concerned with stockpiling enough fuel to last till things return to normal.

Check out this Action Plan – Fuel Safety and Storage to get you started calculating how much food, water, and other supplies your family will require to get through a catastrophe. Spending a little effort and money now could go a long way toward ensuring that you have the fuel you need to cook your food and remain warm if you lose power or natural gas.


Water, food, air, and fuel are the four essential necessities for survival. This puts fuel at the top of the priority list. Storing fuels is far riskier than storing grains or water. Make sure you set up some extra time.

in learning about the fuels you keep on hand and the best procedures for keeping them securely. For more information on a variety of fuels, check see our post How to Safely Store Fuel for Emergencies.
