What is the Best Wood to Burn in a Fireplace? To Burn or Not to Burn

What is the best wood to burn in a fireplace?

Burning wood in a fireplace is an enjoyable and cozy experience, especially during the holidays. However, some wood is better to burn than others, and for a good reason.

To ensure safety, as well as the safety of family and neighbors, it’s important to familiarize oneself with what types of wood are best for burning in the Bay Area.

The density and moisture of wood all play a role in how hot and how long it will burn. The best woods will burn efficiently, leaving the fireplace or stove clean. On the other hand, some types of wood barely burn at all and just fill the home with smoke instead.

Hardwood V.S. Softwood: What’s the Difference?

Some people think hardwood is stronger than softwood because of its name, but this isn’t always the case. In fact, some types of softwoods are actually harder than hardwoods. So what’s the difference between these two kinds of wood, and which is the best for burning?

What is Hardwood?

The easiest way to identify hardwood trees is to look at their leaves. Hardwood trees typically have deciduous (broad) leaves and are usually found in temperate climates. Examples of hardwoods that are good for burning in the fireplace include oak, hickory, maple, poplar, and ash.

Hardwood burns hotter and longer than softwood because it has a higher density. It also produces less smoke, making it a good choice for those living in urban areas.

What is Softwood?

Softwoods typically have evergreen (needle-like) leaves and are often found in colder climates. Examples of softwoods suitable for burning in the fireplace include pine, cedar, spruce, and fir. Softwoods have a lower density than hardwoods, so they burn faster and produce more smoke.

Additionally, they tend to have higher sap levels and more air within their cell structure, which results in a hot, fast burn with a lot of sparks. It is generally not recommended to burn softwood for cooking because the sap can affect the flavor of food.

The Verdict: Hardwood is Better For Burning

Overall, hardwood is the best type of wood to burn in the fireplace and should be used whenever possible. It has a longer burn time than softwood and produces significantly less smoke.

Seasoned Wood is Best

Wood should be seasoned before burning it in the fireplace. Seasoning wood means that it has been allowed to dry out, usually over a period of six months to a year.

Wood that has been recently cut, or unseasoned wood, contains a lot of water – around half its weight. Burning this type of wood to burn can be tricky as it produces more smoke than dry wood and doesn’t burn as well. Seasoned wood has been split, stacked, and stored in a dry area to allow it to dry completely.

Unseasoned or “wet” wood will not burn as efficiently or cleanly and can cause creosote buildup in a chimney, creating a fire hazard. Therefore, when choosing wood to burn, go for seasoned hardwood!

Where to Find Best Wood to Burn in the Bay Area

When buying wood to burn, there are several factors to keep in mind: what type of wood to burn, what size, and what quality. The best wood for burning in the Bay Area is dry, seasoned hardwood.

It should have been cut and split for at least six months to a year and should have an average moisture content of 15-20%. Seasoned wood is dry to the touch, may have loose bark and splits or cracks in ends, and should feel lightweight for its size.

Firewood can be purchased from local vendors, hardware stores, or online. It is essential to check the quality and ensure it will burn properly.

Firewood is most commonly sold in units of a pallet, cord, face-cord, or bundle.

A full cord of firewood is a stack of wood that is 8 feet long, 4 feet deep, and 4 feet high. Most standard fireplaces, wood stoves, or fire pits will require further cutting, so the logs fit them.

A face cord is a wood pile that measures 8 feet long and 4 feet high, and typically uses 16-inch logs–amounting to 64 cubic feet of wood. It is 1/3rd the size of a full cord.

Firewood bundles are one of the most convenient ways to purchase and use firewood. Most bundles are .75 cubic feet, making them easy to carry and handle. Some campgrounds even sell bundles to visitors. Because of its convenience, bundled firewood is often at the higher end of the price range.

If purchasing wood wrapped in plastic, check whether it is dry before bringing it home. If the wood still feels wet, place it on a firewood rack in a sheltered area so it can continue to dry. It’s best to avoid leaning or stacking firewood against a home – this provides a very cozy place for critters to hide.

Safe Burning Rules

1. Check for Alerts Before Burning

Most of the time, it is perfectly safe to burn seasoned wood throughout the seasons. However, when there are high levels of fine particulate pollution in the air, the county may call for a Spare the Air alert. On these days, the no-burn rule applies to both homes and businesses like hotels and restaurants.

Signing up for text alerts about Spare the Air is easy. Alerts are also posted to the Spare the Air and Air District websites and social media pages (Facebook, Twitter, and Instagram). Local radio and TV news media also broadcast the alerts.

2. Only Burn Dry, Seasoned Wood

Burning wet or unseasoned wood is not only inefficient, but it also increases the amount of smoke that is released into the air. Burning moist wood produces more soot, which can lead to chimney and air pollution problems.

Furthermore, burning wet wood can cause wood fires to produce more creosote as a result of incomplete combustion. Creosote smells like tar and builds up over time, eventually lining the chimney or flue.

This substance poses a significant chimney fire risk as it is highly flammable. Some studies have even indicated that creosote is a probable carcinogen.

3. Use an EPA-Certified Wood Burning Device

Fireplaces or stoves must meet EPA standards for certified wood-burning devices. These appliances are more efficient and produce less smoke than uncertified devices, so they are much better for the environment and general health.

New EPA-certified stoves produce no more than 4.5 grams per hour – older and uncertified stoves release 15 to 30 grams of smoke per hour.

4. Never Burn Garbage, Plastics, or Other Harmful Materials

Unfortunately, there’s a lot of misinformation out there about what is safe to burn. Burning garbage, plastics, or other materials not meant for burning can release hazardous chemicals into the air and pose a health risk.

Here are some more examples of materials that are NOT safe to burn:

  • Gift wrapping paper
  • Cardboard
  • Painted or treated lumber
  • Paper with colored print, including newspapers
  • Fire accelerants or firestarters
  • Dryer lint
  • Driftwood

The best fuel for a fireplace is the fuel it was built for. Other fuels may release toxic fumes, burn too hot for the chimney, cause resin buildup, and cause a risk of chimney fires.

5. Avoid Burning Eucalyptus

Eucalyptus wood is readily available in the Bay Area; these trees are invasive and are constantly being cut down. Although they are hard as stone and take years to dry even when cut and split, they are a pyrophyte, just like pine and cedar.

When they catch fire, the sap in them gets hot, boils, and then explodes. Eucalyptus trees were the fuel for the 1991 Oakland Hills fire that destroyed 3,000 homes.

Is There Flammable Debris Inside Your Chimney?

Flammable debris inside your chimney can be a serious fire hazard. If you notice any of these signs, contact a professional chimney sweep immediately.

Whether you have a wood burning chimney or a fireplace with a gas log lighter, flammable debris can build up on the inside—where it’s out of sight and out of mind. Let’s take a look at the top offenders when it comes to fireplace safety.

Soot

Soot is a natural byproduct that accumulates from burning wood. If you have a wood burning chimney in your home, you can be sure you’ve got soot too. Not only is soot flammable, but it’s also fine enough to inhale and contains toxic elements. Be sure to have it removed from your chimney at least once a year.

Creosote

Creosote is a tar-like material that you can find inside a wood burning chimney that hasn’t been cleaned in a while. This substance is highly flammable, so it’s essential to have it removed by a professional chimney sweep. Although, there are a couple ways you can cut back on creosote buildup, such as only burning seasoned wood. Not only does green wood not burn as well, but it also produces more smoke and creosote deposits.

You definitely don’t want to allow creosote and soot to build up inside your chimney. It can spark into a chimney fire that puts your home at risk, but you might not even notice until it’s too late. Another important issue to highlight is that if enough creosote builds up, it can even block toxic gases from exiting the chimney, causing them to remain indoors.

Mold In Chimney

Did you know that mold can grow inside your chimney as well? If there’s moisture in your chimney system, it can lead to unchecked mold growth. This can be caused by things like deteriorating mortar, poorly maintained roof gutters or a faulty chimney cap, so be sure to have a professional chimney sweep look for any chimney damage that could result in this health hazard.

Chimney Flue Damage

In order for your fireplace and wood burning chimney to function properly, the flue needs to be in tip-top shape. But without a professional chimney inspection, it’s tough for homeowners to discover this kind of damage on their own. That’s because a special camera is often needed to really see inside your chimney. If the flue isn’t intact, combustible parts of your home can be exposed to extreme heat, making this scenario a hidden fire hazard.

Animal Nests

Unfortunately, animals sometimes climb into a chimney and become trapped and unable to find their way back out. Another common situation we see is birds or rodents looking for a warm, dry place to build their nests. Nesting materials are flammable, not to mention the mess you’ll find the next time you want to build a fire.

If your wood burning chimney doesn’t have a cap to protect it, don’t be surprised if you’ve had some unexpected visitors, such as bats, raccoons, squirrels, or birds. Even snakes have been found in chimneys from time to time.

WHAT ARE “NO BURN DAYS”?

Spare the Air was formed in 1991 by the Bay Area Air Quality Management District to inform residents when the air quality is forecast to be harmful and to share information on ways to decrease air pollution. No Burn Days are also called “Winter Spare the Air” days.

In 2008, the Air District approved a rule that makes it illegal to burn firewood on days once a Winter Spare the Air alert is in effect. This guideline was adopted to protect public health.

During winter months, wood smoke is the major source of air pollution in the Bay Area, accounting for more than one-third of fine particulate substance pollution. On cool, peaceful days when there is an inversion layer of warm air acting as a cover over a layer of cold air, wood smoke can build up at ground level to harmful concentrations.

There are numerous things residents can do to decrease their impact on air quality over the winter, when these weather conditions endure. The first line of protection is to limit usage of wood-burning stoves, and ideally switch over to a different heating method, such as gas, or EPA-certified wood stoves.

CHECK FOR ALERTS BEFORE YOU BURN

Never fail to spot an alert by signing up for Winter Spare the Air Alerts. Modify your alert for text, email, or phone call. Winter Spare the Air Alerts will as well be posted to the Spare the Air and Air District websites and social media.

KEEP IN COMPLIANCE

Besides avoiding burning wood on Winter Spare the Air Days, there are additional provisions in the wood-burning rule.

Wood-burning devices are forbidden in new buildings constructed in the Bay Area. Gas-fueled fireplace, gas inserts, and electrical fireplaces are acceptable.

We want you to stay warm this winter, but make sure you first check if that day is a “no burn day” by visiting the Spare the Air website.

PREPARING YOUR FIREPLACE FOR FALL AND WINTER

Nothing is more pleasing when the temperature drops than the soft amber blaze of a crackling fire. But before you light up that firewood, there are numerous steps you need to take to get your fireplace ready, and for excellent reason. Prepping your fireplace for fall can:

  • Improve the air quality in your house
  • Avert fires
  • Save energy
  • Keep your home warm

Chimney preparation steps are given below:

ARRANGE A YEARLY INSPECTION

All chimneys should be examined and cleaned by a chimney cleaning company at least once a year. A careful cleaning will eliminate any buildup of creosote, an oily and extremely flammable byproduct of burning wood, gives you a safer fireplace.

CLEAN THE FIREBOX

Eliminate and clean the grate and other accessories that are inside the firebox. Vacuum or remove the ash and store it in a metal container with a sealed lid. There are several ways you can recycle the ash. You can use it in your backyard as a fertilizer, to dissolve ice, and even clean the fireplace doors, for example. Be sure to keep a small amount of ash. It will help with starting your initial fire of the season.

CHECK FOR CRACKS AND DAMAGE

Check for cracks and wobbly joints of the firebricks inside the fireplace, and check the external masonry for damage. Hire an expert mason to do any repairs—never try to repair firebrick with ordinary mortar, as the blend cannot stand up to high heat.

EXAMINE THE CHIMNEY CAP AND DAMPER

Ensure the fireplace damper is working accurately and that there is no wreckage preventing it from opening and closing. Make sure that the chimney cap is firmly attached and in good condition. The cap should comprise protective screening to keep birds, squirrels, and other pests from entering the chimney.

CLEAR AWAY TREE LIMBS

While you are outside examining the chimney cap, trim any overhanging tree limbs that may be squeezing on the chimney. Tree limbs can restrict the proper draft of the chimney and spoil the cap.

CLEAR OUT ASHES

Clean out the firebox once in a week, or whenever the ash is more than an inch deep. Coals can stay hot for up to three days, so ensure everything is completely cold. Remove or vacuum the cold ashes and dispose it outside—wood ashes are just right for garden beds and compost piles.

HOW TO PREP A GAS-BURNING FIREPLACE

Clean the blower

Check your gas-burning fireplace to see if it has a blower. If it does, clean it. Distinct from furnace blowers, the blowers of gas-burning fireplaces do not have a filtering system to stop buildup. Dust buildup can cause early wearing of the bearings. Dust can insulate the motor, which prevents it from cooling correctly, eventually leading to motor failure.

Replace batteries

Before every season, change the batteries in any remote transmitters and receivers, if appropriate. Also, replace the batteries and examine any smoke or carbon monoxide detectors to ensure they are working properly.
