Tips for Properly Seasoning Firewood

Keep these tips in mind while seasoning firewood to heat your home.

Want to heat your rural home without gas or coal? In Wood Heat (Firefly Books, 2014), author Andrew Jones provides a useful guide to using wood to heat your home. Jones dissects the environmental and economical upsides and downsides of heating with wood while providing advice and instructions that are necessary to help you successfully produce enough energy to keep your home warm during the winter. This excerpt, which discusses drying and seasoning firewood for use, is from Chapter 2,”Wood.”

You can buy this book from the MOTHER EARTH NEWS store: Wood Heat.

Tips for Properly Seasoning Firewood

Wood is essentially a mass of tiny long tubes, or cell cavities, that run the length of the tree. Moisture exists both as “free water” in these cavities and as molecular water that is locked in the cell walls. When a tree is felled, the slow process of drying begins, and the free water is the first to evaporate. Once the free water evaporates, the moisture content of the wood is around 30 percent. This is called the “fiber saturation point.” After this, water begins to leave the cell walls, and the wood starts to shrink and crack.

For optimal burning, firewood should be dried, or “seasoned,” until its moisture content is less than 20 percent. Firewood with a moisture content higher than that may eventually burn, but it is devilishly hard to light and just as hard to keep burning. Also, your new high-efficiency wood-burning stove or furnace is guaranteed to perform sluggishly as it struggles to burn freshly split, or “green,” firewood—much of the heat and energy content produced are wasted in drying the wood’s excess moisture. Just as important, the stove does not burn the tars and creosote in the smoke produced by the fire, and they end up lining the inside of your flue pipes and chimney. They also blacken the glass windows of your wood-burning appliances and produce a lot of blue-gray smoke, fouling your house and annoying your neighbors.

Seasoning wood has another important but less obvious benefit—when wood is properly cut and stacked right away, mold has less opportunity to establish itself. Throwing unseasoned firewood into a pile allows mold to spread throughout the logs, mold that you unwittingly release into your home’s environment when you bring the firewood inside throughout the heating season.

You can buy already seasoned firewood or buy it green and season it yourself. How can you tell whether wood is properly seasoned? It's possible to test the wood with a moisture meter, which measures resistance to a small current and converts it into a moisture-content reading, yet this reading can vary widely from one area of the log to another. With a little practice, however, you can use the following tips to judge accurately for yourself whether your wood is dry. Use as many as you can for the best results.

Human-powered DIY wood splitter

Ingmars klyv II, Human-powered DIY wood splitter

Yes, the splitting maul and axe also are human-powered but this is a machine that appears to be doing it with a lot less effort and much safer.

Human-powered DIY wood splitter

The machine does most of the work, but the operator is in total control, with no fuel, no noise (except the wood cracking), and pretty low budget, both on funds, and labor.

The wood splitter is entirely created from scrap that the maker seems too have had laying around his property and thus it has cost him very little to any in funds.

Managing your woodlot

by Michael Smith

In this current climate in Europe with the demand for firewood being at an all-time high anyone who has the slightest idea how to manage the woodlots on his property can make quite some money.

Many people in Britain and also elsewhere do have their own little or even not so little woodlots on their property but have no idea as to how to mange it for their own benefit and also for profit, as far as firewood and such are concerned.

In addition to that there are farms that have quite a bit of woodland, even to such an extent that those plots of woodland are being used for shooting and such like. Very often, however, the tress are left to their own devices, so to speak, and no real management is being undertaken.

The same, in a way, is true for wooded parks, municipal or otherwise, where trees that have fallen are, unless the pose a danger, left where they have fallen to just rot away.

In other cases, where trees are cut in countryside management and municipal and public parks the trees are often cut into lengths and then left as “habitat piles” laying about higgldy-piggledy piled up. This is lazy forestry practice in fact despite the claims that it is “for the wildlife”.

In years gone by when people has Estovers rights and such like and even when it was no longer used in such ways woods and forests – including parks – did not have any of such debris left laying about and neither were logs left, and still wildlife thrives. More at times, it would seem, that today with the “habitat piles”.

Many forestry authorities are now advising against such “habitat piles” and that for more than one reason. The main reason being that those higgledy-piggledy left piles cause diseases to spread amongst the trees and therefore the advice is no to build proper “habitat piles” where the logs are sunk into the ground some way. That, however, requires time and effort.

The other reason is that trees left to rot in the woods and forests are a CO2 hazard, do to speak, for int heir decaying process the wood that is left to rot releases the CO2 that it has absorbed during its growing process. Fart better, therefore, to use the wood, even if it is just for firewood. The release of CO2 if the same but the heating with wood is carbon-neutral.

Also to be considered is that during he decaying process of the wood left laying about not only CO2 is set free but also a much more dangerous greenhouse gas, namely methane. This does not occur when the wood is burned.

So, instead of leaving the wood to die out there in the bush it is time to bring it in and turn it into an income, even if it be just a small one, whether for a farm or a municipal and public park or those that manage the countryside areas.

With the current demand for firewood for homes and – it could soon be – power stations we cannot afford to leave wood too rot out there.

If the right methods be applied some of the country's heating needs and those of power stations could be met by that wood which no one wants for anything else or which has no other market.

The issue of the Dutch Elm Disease in Britain could also be solved – to a great extent if not entirely – by removing all dead and dying elm trees and burning the wood in homes or better still power stations. The reason I recommend power stations here is because the wood then is not going to sit on someone's porch or in someone's yard at home for the beetle to mature and swarm and infect further trees with the pathogen that the, inadvertently, carry about.

Within less than a generation, if done correctly, the Dutch Elm Disease could, I am convinced, be overcome, if the above be employed. Other diseases too could be dealt with in this way, e.g. felling the diseased trees and burning the wood.

This is a case of killing two birds with one stone: removing – hopefully – the disease and providing carbon-neutral energy.

From the woodland owner's side this, obviously, does require some more work than just leaving things to fall and then in situ as they are. It requires the active cutting and bringing in of the wood and then preparing and selling it. The reward, however, could and should be grater here than the outlay, in finances and time.

It can be done because it used to be done. We have but become lazy in our management of woods over the years as, to some extent, the market for firewood was not there and the demand was rather low, and also as we were told in woodland management by certain people with little knowledge who thought that they knew it all to leave the wood as “habitat piles”. This, however, has caused more problems than that it did good; something that anyone with just half and ounce of brain could and should have seen coming.

If you leave diseased wood out there to rot down then you will spread the disease to other trees. This is so obvious but those misguided environmentalists who thought that they knew it all did not care about the trees and the possible income from those; all they cared about was invertebrates and such like needing a place to be.

What did they think those creatures did before when all woods and forests were managed properly, including for firewood and very little debris was lost? They lived quite well on the forest floor without human interference of giving them piles of wood to chew.

We cannot afford this practice, and in fact never could, for it caused disease to spread. Today, however, we can afford this even less for it is not beneficial for anyone, not at least the environment, that we import firewood from as far field as Poland to satisfy the need in Britain, especially as we here waste such wood.

It is most urgent that we manage our own woodlots, whether on farms or elsewhere, in such a way that they benefit us all.

The use of firewood is, as I have said before, carbon neutral as the wood only releases the amount of carbon that it accumulated during its growth. The same carbon is also released while the wood is a “habitat pile”. So not all that good for the environment, is it now.

Much better, therefore, to burn the wood and to have carbon neutral energy rather that to waste it by letting it rot in the woods.

Managing woodlots for firewood, especially if only dealing with dying and fallen timber, is not rocket science and the market is out there, at least presently, for firewood, and if we keep on at the right people the market may even get bigger as time goes by, especially when everyone realizes the facts about carbon neutrality of firewood.

This does only, though, really work, as to locally harvested firewood and not too that that has been imported from nearly as far afield as Russia. That is not a sustainable way to go. Using homegrown wood, on the other hand, is.

While I have been addressing here the British market, the lesson applies also for other countries. I do know that in other countries this seems too be understood far better than in Britain, such as in those of Europe and especially in the USA and Canada, but still there are some people who have little idea of how to get people to buy firewood because some see the smoke as an issue, as far as being “green” is concerned. However, the carbon neutrality of firewood is what should be considered by all of us; the smoke is something that is secondary and negligible, especially as far as untreated natural wood is concerned.

So, let's hear it for local firewood.

Home fires are burning again

With wood stove sales and use up in UK logs having to be imported from as far as Eastern Europe in order to satisfy demand

by Michael Smith

Considering the global recession and, more recently, conflict over natural gas flowing into Europe from Russia, this was probably something that should have been expected.

Sales of wood-burning stoves in the UK, as well as the use of existing wood-burning stoves, have risen recently, which in turn is causing shortages of firewood. This is forcing some suppliers to go so far as Eastern Europe to find good seasoned wood.

In medieval England, peasants were allowed to collect as much deadwood as they wanted from the royal forests - just so long as they could reach it "by hook or by crook". But the rapidly rising number of households now turning back to the forest for fuel, to protect the environment, or to simply make a lifestyle statement are finding a supply chain of this renewable, carbon-neutral fuel far more complex. Others may not try to make a lifestyle statement at all but are returning to wood out of bare necessity as heating fuels had become rather expensive and many rural households reply on heating oil rather than gas for hating home and farm.

Gas supplies have become a little – now this is an understatement – uncertain with Russia every now and again throwing a wobbly and a tantrum and oil seems to be going on a high every few minutes and when the prices do fall again to quite a low, as happened recently, the oil companies are in no hurry whatsoever to pass the reductions on to the consumer.

Sales of wood burning stoves in the UK are up 50% in the last three months of 2008 compared to 2007 and, according to forestry consultant Vince Thurkettle, demand for wood is currently increasing 25-30% a year. This on an island that is a bit more than 10% wooded and produces about 1 million tonnes of firewood a year, according to the Forestry Commission.

This proves, yet again, that we must bring the old coppice woodlands back into production – this has to happen anyway if we do not want the coppice stools to fall apart – for the production of small lumber and especially the production also of firewood. About time too.

This rising demand is causing a shortage of good logs, which combined with prices as high as £95 ($139) per load of wood in the north and west of the Britain is causing some wood sellers to import wood from hundreds of miles away; from inside the UK from countries as far away as Kent, Surrey and Sussex. Those are listed as “favorite hunting grounds” for wood sellers but they even (have to) go as far as Eastern Europe in order to get wood for resale.

So, some people are apparently driving wood, presumably in diesel-powered trucks, across all of Europe, to be burned in wood stoves and fireplaces in Britain.

Is importing logs from the other side, the far side, of Europe really a good idea? Personally I do not think so. And would it really be necessary? It would not if Britain had kept up with the demand that was coming – and it was obvious that it was coming – for wood.

Even though the information officer at the Forestry Commission’s Biomass Energy Centre described the effects on the environment of burning wood, compared to oil or natural gas, as “negligible”, even if that wood has been transported by road or sea, that is really something that I do not buy – as yet – and would have to see the numbers for that first. I have a very hard time believing that trucking in wood from Poland or even further afield to the British Isles to burn for heat makes environmental sense.

The good thing about burning wood for hear though is that it is – theoretically – carbon neutral, in comparison to so-called fossil fuel, which includes the likes of coal, oil and even natural gas, as wood only releases that much carbon as it has taken up during it lifetime as a tree. Nice one there. Just something that some environmentalists have problems understanding because of the fact that wood releases visible smoke and, depending in how well the wood has been seasoned, or not, as the case may be, the smoke can be quite dense.

There are two woods, however, that are best burned unseasoned on a base of other wood that has started the fire and that is beech and birch. Those two initially release a gas when burned in their green state that makes for a very hot fire.

"The dramatic upturn in demand for firewood is fantastic news in many senses because, in theory, we have so much of this resource that it is hard to see it ever running out," Thurkettle says. "Yet after so many years of relying on coal and gas to provide most of our energy needs, we have lost the art of effective woodland management. Until we relearn how to assess, manage, cut, store and burn exclusively local wood, we will continue to squander the potential of our woodlands."

The problem is that he is so very correct with that statement and speaks about just the issue that I keep mentioning as well.

We must get back to proper woodland and forest management, also as regards to firewood, and get away from the wasteful practice of the habitat pile. The habitat does very nicely without them things too, thank you. It has done so in the times of the use of the Estovers rights and will do so still today.

I have seen well managed woodlands where little if any debris was left where there was more wildlife – including invertebrates and fungi – than in many of those places that are full of those habitat piles. On the other hand those places that have clean forest floors have fewer diseased trees, especially as to fungal and pathogen problems.

On the other hand all that wood that is used – misguidedly too often – in habitat piles (while some are a good idea to leave all wood lying about or that purposes causes problems) could find a much better use to heat homes or even power turbines. The wood that is left too rot also releases the came carbon that the one that is being burned releases; so why waste the material and allow it to rot away.

Bringing in firewood from as far afield as Poland and elsewhere should not be necessary and certainly is not a practice that should be encouraged. It should be discouraged, in fact, for this can lead to destruction of woodlands and forests in Poland and other such countries to fill the UK demand.

While it is said to be still better for the environment to burn wood that has been trucked or otherwise shipped to the UK it is not ethically the right thing to do.

Time we got back to proper woodland management and relearned the old skills of how to manage woods and forests, aside from all the other reasons, for firewood. The trees that need to be removed every now and then, and presently, because of the bleeding canker infections of Horse Chestnut and similar diseases in other species of trees, those are quite a few, have to be removed from municipal parks and especially the country parks and such like, should also be entering this “food chain” of firewood instead of being allowed to be left on site to rot away.

If this means training municipal park gardeners, foresters, wardens and rangers in the appropriate chainsaw skills and allocating one or two members of staff to the logging up of any such trees into firewood then so be it. This could be a way for such places to create a little source of income. And while this may not be a very regular income of the same amount year in year out it nevertheless should be something that should be pursued.

Now let's hear it for local firewood.

I rest my case...

East Tennesseeans switching to firewood to save money

In order to save money this winter, some residents of East Tennessee are switching to firewood for their heating

by Michael Smith

One resident of the State who decided last year to switch solely to firewood instead of using propane gas to heat his home says that it cost him about $350 for the wood to warm his three-bedroom, two-bath house and with energy prices even higher this year, it is something he certainly will continue. He reckons that with the rate then it has saved him $600 and with the ever increasing prices it will be even more so. Others are looking into the old-world energy source as well.

Aside from the fact that it is, more than likely and especially if one has access to a cheap source of wood, a cheaper way to heat a home (and whatever else) than using gas or oil and even coal, it is also much more environmentally friendly. Burning wood is, basically, carbon neutral for the only carbon released is that that the wood used in order to grow and mature.

Many, like the Tennessee resident mentioned, in that State and elsewhere, and not in the USA alone, made and are making the switch to heating and even cooking with wood because of the
skyrocketing prices for gas and other sources of heat and cooking source.

Having said before that the saving that was made by this particular resident was $600 and that with the increasing costs of gas and oil it may be even more in the future we can, though, of that I am sure, be certain that the price of firewood is going to go us as well as demand increases.

Soaring energy costs and threatened scarcity of some fuels like home heating oil this year have led more homeowners to seek alternative sources for heat, and as a result, both seasoned firewood and some supplies of wood-burning stoves are expected to be in short supply.

The demand for wood-and-pellet burning stoves has caused local sales to increase this year, and already firewood sales have taken off about a month early.

The owner of Ben's Firewood in Knoxville said that while they normally start the winter season around October this year it has already started. People are apparently so worried that things are going to get worse, so they are lining up before it gets too bad.

The push for alternative home heat has largely been driven by the Northeast, where the price of heating oil, still the primary method for home heating, has soared. The average household is projected to spend more than $2,500 this winter, according to the Energy Information Administration, a 30 percent increase from last year. And even with crude oil prices - which factor largely into the price of heating oil - falling to a six-month low recently, the price of heating oil was still just under $3 a gallon, its lowest price since early March. Prices once were projected to hit as high as $4 a gallon.

The Knoxville wood- and coal-burning cook stove company already is backlogged on its most popular item, the Torridaire coal heater, a stove that requires no electricity. Stove sales are typically higher after natural disasters, such as Hurricane Katrina, and when economic times are a little rough.

Sales also are up for many firewood dealers - business is up 40 percent in many cases - and the true firewood season has not even begun yet.

But the seasoned wood, or wood that has been dried naturally for about eight or nine months, is quickly becoming in short supply, since it has to be cut around March in order to be ready for winter months.

Kiln wood, or wood that is accelerated through the drying process by sitting four or five days in a 190-degree oven, also is limited based on how much that kiln can produce.

There are, on the other hand, woods that can also be burned green and some burn better and hotter green than seasoned and those are beech and birch. Where they are in ample supply things should not be too bad.

A full cord of seasoned wood will replace about 300 gallons of diesel fuel for heating a home while green wood would only replace about 225 gallons. The difference is water content - the more water that's in the wood, the more water you have to burn off before you get any heat. But even burning green wood is still cheaper than any other energy source.

The most important part in all of this is, however, and this must be observed, that the wood comes from well managed and renewable sources and that it is replanted.

In the UK, if would go back to firewood, and in many places we certainly could and even should, nay, let me rephrase that, must, the coppice woodlands could, once again, come into their own and new ones can and must be planted.

Coppicing, I am certain, could also be done in other countries and environments, such as in the United States.

Wood shortages will, no doubt, occur, especially in the places where it is more used such as in the rural areas of the USA and elsewhere, especially shortages of seasoned wood. Another source of firewood that should not and must not be overlooked for those that need to watch pennies is waste lumber from building sites. The only worrying aspect here could be the release of certain chemicals that were used in the wood, as some building lumber, even if only used for shoring up, is treated.

There is a lot to consider when deciding to switch to alternative heating, such as buying a wood- or coal-burning stove, but many of them do burn more efficiently and cleanly than they did in the 1980s. While there will be more cost up front for a stove, most mid- to lower-level priced stoves should pay for themselves in about two or two and a half years.

As for firewood, it is recommended buyers check references of dealers and be sure to have their chimneys swept at least once a year.

If you have got any amount of land or access to land, and a chain saw, you have basically an inexpensive fuel. A lot less expensive than fuel or gas or electricity.

Phase out coal and burn trees instead, a leading scientist urges

by Michael Smith

Now, what a good idea. This could put forestry really back on the map.

The world and the human race, in short all of us, must urgently embark on a massive program to power civilization from wood to stave off catastrophic climate change, one of the world's top scientists said recently.

Twenty years ago, Professor James Hansen was the first leading scientist to announce that global warming was taking place. Now he has issued a warning that a back-to-the-future return to one of the oldest fuels is imperative because the world has exceeded the danger level for carbon dioxide in the atmosphere. Current targets on emissions are 'a recipe for global disaster, not salvation' he said.

We have recently only made mention of this, that is to say, that the burning of wood is much better than the burning of anything else for heating and, so I am sure, powering electricity generation. Here especially via CHP plants.

Growing trees, which absorb the gas from the air as they grow, burning them instead of fossil fuels to generate electricity, and capturing and storing the carbon produced in the process is needed to get the greenhouse effect down to safe levels, he says.

The dear professor talks about storing the carbon produced from the burning. May I ask what for? If we grow trees for burning then all we release is the carbon that the trees absorbed over their lifetime and the carbon released will “feed” other trees which, in turn, will be going the same way, e.g. into the furnaces.

We must not, however, grow special woods for this but should and must use the wood from the current forests and woodlands that are being managed. No, dearest misguided eco warriors, we must not leave the woods and forests unmanaged. On the contrary, they will only thrive if they are managed and especially if they are managed as a means to reduce our impact on the global climate. Forests and woodlands, properly managed and cared for, are our best insurance policy.

We also must plant new forests and woodlands urgently, but those must, as I said before, made up of a mixture of woods and not be mono-cultures.

The level of carbon dioxide stands at 385 parts per million (ppm), about 100ppm above what it was at the start of the Industrial Revolution. It is rising by about 2ppm a year. The most ambitious international efforts focus on stabilizing it at 450 ppm, though few see this as achievable.

One can but wonder as to whether anybody has ever though of linking the fact that the carbon dioxide level has risen that much with the fact that ever since the Industrial Revolution we have been cutting down trees as if there is no tomorrow and where we do not cut them down now we let them rot. The process of wood rotting also releases carbon dioxide, namely that which the tree, over its lifetime, stored.

Aside from the fact that climate change is a natural cycle of the Earth, the increase in CO2 is more than likely due to the fact that the world's carbon sinks, the forests, have been shrinking ever since the Industrial Revolution because of our insatiable hunger for wood (later to a degree to be replaced by coal and then oil) and when it comes to the large forests in Canada that are cut down to be made into paper tissues and paper towels (whatever is wrong with a cloth handkerchief and a cloth towel?) by the likes of Kimberley Clark, the producers of Kleenex and other brands, and the wholesale slaughter of trees in the Rainforests of the world, now even in the pursuit of a green goal, that of bio-diesel, are still shrinking at an alarming rate today.

There is but one answer: stop cutting down all the forests willy-nilly and turn them into sustainable management, to be managed for all our needs, be this furniture and building wood, firewood and others products. We also must get away from the notion of the “habitat piles” of wood to be left rotting in the woodlands and forests. They release CO2 back into the atmosphere without benefiting anyone and in addition to that much of the wood that is left “as habitat”, which would years ago have gone to homes as firewood, is in fact creating a danger for the woods and forests, in the form of fire hazards as well as a haven for tree diseases.

But Professor Hansen says that he is convinced that 350 ppm is the absolute maximum that will avoid the loss of the polar ice sheets and other disasters. He says that all coal power stations must be phased out by 2030, unless they are equipped with special "carbon capture and storage" equipment that stops the gas escaping into the atmosphere. If that was done, the level could be stabilized at 400 ppm. After that, a vigorous program of planting trees to suck up carbon dioxide – coupled with the use of carbon capture equipment when the trees are burnt, and improvements in agricultural practices – could get levels down to 350 ppm "within a century".

As I stated above, there is no need to capture the carbon from the burning of the trees as the CO2 thus released will be absorbed again by the new trees that are being planted and those that are still growing normally. Carbon is the natural food of the trees and therefore there is no real need to use any carbon capture when wood is being burned.

However, we need more trees and more other green plants, plants which will absorb CO2 as food.
