Building a Firewood Shed and Other Wood Stove Accessories

You may not think of a firewood shed as a wood stove accessory, but, in the big picture, it is one of most important. You might have the best gas chain saw, extra chains, sharpening tools, and fireplace tools, but if your wood is wet it will not burn.

The shed need not be fancy or expensive, neither does it have to be a messy pile of boards and tarps. You can buy ready made firewood racks, but they tend to be rather small and expensive. If you only use wood for taking the chill off or for the occasional atmosphere fire, then a small ready made one will work just fine.

Building your own shed can be a very satisfying project that can include other family members. Because it is a shed, not a kitchen cabinet, there is plenty of room for error and it will still work well. When small children are allowed to help Dad with such projects, the memories can last a lifetime. Hammering and sawing boards can be a great learning experience, and a firewood shed is the perfect kind of project to work on together.

It is important to decide on the size of the shed, which will be determined by how much wood you expect to use for the winter. In Vermont a typical house uses 5 cords of wood for the season. This is a lot of firewood, and it might be more than you are willing or able to build a shed for.

A full cord of wood is 4 ft. x 4 ft. x 8 ft., or 128 cubic ft. From this, you can calculate the size of shed you need. You can also use the basement, a garage, several sheds or one shed and several covered piles.

The wood needs to dry at least 6 months before burning. If the prevailing winds and weather tend to make the wood wet, you should consider adding at least a partial wall to the shed to protect the wood. The more air exposure the wood has, the better it will dry.

Other wood stove accessories you will need, if you are going to use a new or used cast iron wood stove or fireplace insert, would include a metal ash pan, shovel, floor protector, and stove top water steamer.

The dangers of using green wood are real and can result in a chimney fire. The moisture in the wood cause it to burn incompletely, which makes the wood smolder, rather than ignite. The gases emitted condense on the walls of the stove pipe or chimney and solidify as a coating of condensed fuel, just waiting to ignite.

If the chimney is coated with creosote and you have a very hot fire, or a lot of sparks and flames, the creosote may ignite into a torch like fire. This fire sounds like a rushing wind as it explodes in the chimney, and the temperatures can be high enough to actually melt stove pipe or adjacent combustible materials.

Alcohol Camping Stoves Are the Smallest, Lightest and Easiest Backpacking Stoves Around

Alcohol camping stoves are the perfect choice for the backpacker looking for a small, lightweight, easy-to-use and inexpensive stove.

The alcohol camping stoves are very simple, they have very little moving parts, no jets or orifices to clog and clean. Alcohol is a renewable resource and is a non-petroleum based product. If you have a spill in your backpack, it will evaporate quickly, leaving no tell-tale odor. It's the perfect "green" fuel.

Ok, let's look at the pros and cons for the alcohol camping stoves...

PRO

1. Simple - No Pumping, Pressurizing, Priming or Pre-lighting.
2. Fuel - Renewable, Evaporates quickly, Burns clean (no soot), Not oily or smelly.
3. Lightweight - Can weigh as little as a few ounces.
4. Reliable - They light first time every time, as long as you guard your match against the wind.
5. Safety - Fuel evaporates quickly and will not explode (non-inflammable).
6. Fuel Transport - Easy; can be carried in a plastic bottle. Do not use an untreated aluminum bottle. If you're not sure, don't use it. See the note at the bottom of the page.
7. Fuel Availability - Everywhere; can be found in drug stores to hardware stores.
8. Noise - Very quiet and generally cannot be heard. This can also be a con.

CON

1. Noise - As I said above, being quiet can be a pro or a con. Pro in that it is quiet, but a Con because you sometimes cannot tell if you have a flame or not.
2. Flame - Alcohol burns clear (slightly bluish) and this makes it very difficult to see. Especially in the daylight.
3. Heat Output - Alcohol camping stoves put out about half of the heat per ounce other liquid fuel stoves produce, i.e. white gas, kerosene, Coleman style fuels, and butane or propane.
4. Group Size - A small group of 1 or 2, maybe 3, is best, because of the slower cooking time. This isn't really a con, but it is something to consider.
5. Cooking Time - Is slower because of the reduced heat output, but for 1 or 2 people it is just fine.
6. Safety - NEVER, NEVER fill the stove with more fuel while it is still burning or hot. This actually goes for ALL stove types.
7. Cold - Alcohol camping stoves are not very reliable in freezing weather. As the temperature drops, the evaporation rate of the alcohol drops. This makes them very hard to start. A work-around for this is to pre-heat the stove with a candle.
8. Durability - Since they are so small and lightweight, they can be fragile. They can be bent, crushed or destroyed easily without the proper care.

Do-It-Yourself (DIY): Alcohol camping stoves are perfect for the DIY crowd. The internet is full of instructions on how to make an alcohol camping stove.

FUEL

1. Isopropyl - NOT Recommended. This can be purchased from any drug store, but it will always have too much water mixed with it. It's never just pure alcohol.
2. Denatured - This fuel comes mixed with other poisonous chemicals. Many times the label will say that it is suitable for marine stoves. I would go with that brand. Another way to tell if the denatured that you have will be any good, is to burn some of it in a metal dish and check for any residue left behind. Do not use it if there is any residue.
3. Grain - Alcohol works well, but can be expensive. Stay away from the colored grain alcohols and go for the clear such as the Everclear brand. Keep in mind that you brought it to use in the stove and not to keep your belly warm. P.S. This is the only fuel than can be consumed by humans. ALL the others are poisonous.
4. Methyl - Other names are methanol, wood alcohol, methyl hydrate, liquid fondue fuel, gasoline line antifreeze. This is a highly poisonous fuel. However, methanol evaporates faster than ethanol at all temperatures and you would have a better chance of starting your stove in cold weather. Store this fuel and the stove that uses it from your food and pots.
5. Gelled Alcohol - Such as Sterno, Canned Heat, Jelled Alcohol. This is good for keeping food warm, but not for cooking. Not enough heat output.
6. Diethylene Glycol - Extremely poisonous and is Not Recommended.

Types of Alcohol Camping Stoves

1. Open Flame - This is the simplest of all the alcohol camping stoves. It's basically an open shallow metal container that you pour the alcohol in and you light it. The pot is sitting on a wire frame above the stove. They are simple to build and operate, but are not the most efficient with the fuel to heat ratio. However, they are a very reliable stove.
2. Chimney or Updraft - This style of stove utilizes the updraft created by the heat of the fire, up a chimney, to the top of the stove and heating the pot. It mixes the air with the fuel at the bottom of the stove to get a better controlled flame at the top. The pot sits on a stand above the stove. It has a good heat output and is very reliable.
3. Low Pressure Side Burner - This utilizes the low pressure draft created like the Chimney stove, but the pot sits directly on the stove. Same stove as the Chimney stove, just a different way of using it. It has good heat output and does not need a pot stand.
4. Open Jet - This stove works by vaporizing the fuel and shooting it out little jets. The fuel is poured in through the top center; it is very lightweight and will simmer, but is only good for small pots. You will need to have a pot stand to keep the pot off the stove.
5. Hybrid Side Burner Jet - This is like the Open Jet, but the vents are on the side. The pot sits right on the stove top so a pot stand is not needed.
6. Pressurized Jet - This is like the Open Jet stove, but the center is closed allowing the fuel gasses to build up pressure. It burns hot and does not allow for simmering. You will need a pot stand for this stove.

Points to Consider

1. Consider making an alcohol camping stove for yourself.
2. Are you going to be doing a lot of extreme cold weather cooking?
3. Burner style - You do not have to settle for just one style. You can have a different style depending on weather conditions and/or altitude.
4. Boil time to fuel usage ratio - This ratio is how long does it take to boil 1L of water to how much fuel is used. This is very important when you are determining how much fuel to carry with you.
5. Flame control - Do you want to be able to simmer or not?
6. Size of group - Remember that 1-2 people are best per stove.

Note: Aluminum: "SIGG, one of the oldest and largest manufacturers of reusable aluminum bottles, actually lines their aluminum with an FDA approved coating that prevent toxins from leaching." According to Elizabeth Borelli of Nubius Organics.

Camping Stoves - Come on Baby Light My Fire

Whoever invented camping stoves should be awarded a knighthood in my own humble opinion. On our first camping trip I almost lost my entire family to starvation after I insisted that camping was about getting back to nature, remarking on the fact that I had never seen or heard of camping stove trees in the wild.

Armed with enough matches to build an entire generation of matchstick men, we embarked on our journey with full stomachs and a cold bag full of uncooked food ready and waiting to be introduced to a roaring campfire.

I can safely say that there was a lot of roaring but can confirm that the only fire within our vicinity was the one in our empty bellies. After several hours of failing miserably to get the campfire lit the only thing that was smoked in our camp was us.

I am now a fervent advocate of camping stoves. Our stove has changed the way we feel about camping. We now enjoy tasty, healthy and cooked food around our campfire.

Camping stoves are very reasonably priced, and are easy to research and find online.
There are however some simple considerations to bear in mind when deciding which one is right for you.

Fuel Source:
Different makes and models use different fuels. Decide on the fuel that you are most comfortable with. What weight you are happy to carry around and how easy it will be to buy extra fuel in your camping vicinity if you run out. The most popular and convenient is white gas.

How many people will you want to cook up a storm for? You will need to decide how many burners you require, or what size grill will accommodate your needs if that is the route you are taking.

Weight and Size:
Take a moment to consider how far you will be transporting your camping stove off road. If you will be eating within a short distance of your auto then this will not be such a major consideration. However, of vital importance is the ability to actually fit your camping stove into your mode of transport. My first choice had to be returned for this very reason.
