It’s a deeply satisfying process, and this guide is designed to help you unlock those hidden benefits while maximizing the efficiency and enjoyment of your Ember Hearth wood-burning stove insert.

Think of it this way: you’re not just burning wood; you’re releasing the stored energy of the sun, captured by the tree over years, even decades. You’re participating in a cycle, a dance between nature and human ingenuity. This guide isn’t just about splitting wood; it’s about understanding wood, respecting it, and utilizing it in the best possible way.

I’ll share my experiences, from felling my first tree (a slightly terrifying but ultimately rewarding experience) to developing efficient firewood stacking methods that minimize drying time and maximize space. We’ll delve into the nuances of wood species, the importance of proper seasoning, and the tools and techniques that will make you a true master of your wood-burning stove insert.

Understanding Your Ember Hearth Wood Burning Stove Insert

Before we even think about wood, let’s get to know your Ember Hearth insert. This isn’t just a metal box that burns wood; it’s a carefully engineered appliance designed for efficient and safe heating.

• Key Features: Familiarize yourself with the specific features of your Ember Hearth model. Does it have a catalytic combustor? An air wash system? Understanding these features is crucial for optimizing its performance. Consult your owner’s manual religiously!
• BTU Output: Know the British Thermal Unit (BTU) output of your insert. This tells you how much heat it can generate. This is crucial for sizing your wood supply.
• Firebox Size: The firebox size dictates the length and diameter of the wood you can burn. Most inserts have a maximum log length, typically between 16 and 20 inches. I recommend sticking to the lower end of this range for easier loading and better airflow.
• Air Controls: Mastering the air controls is essential for efficient burning. Experiment with different settings to find the sweet spot for your wood type and desired heat output. Remember, more air isn’t always better. Too much air can lead to rapid burning and heat loss up the chimney.

The Science of Wood: Green vs. Seasoned

This is where the woodworker’s perspective comes in. Understanding the difference between green wood and seasoned wood is fundamental to successful wood burning.

• Green Wood: This is freshly cut wood with a high moisture content, often exceeding 50%. Burning green wood is inefficient, produces excessive smoke and creosote, and generates less heat. It’s like trying to run a car on water – it just won’t work well.
• Seasoned Wood: This is wood that has been air-dried to a moisture content of 20% or less. Seasoned wood burns hotter, cleaner, and more efficiently. It’s the fuel of choice for your Ember Hearth insert.

How to Tell the Difference:

• Weight: Green wood is significantly heavier than seasoned wood.
• Splitting: Green wood is often tougher to split.
• Cracks: Seasoned wood often has cracks or checks in the end grain.
• Color: Green wood may have a fresher, more vibrant color, while seasoned wood tends to be duller.
• Moisture Meter: The most accurate way to determine moisture content is with a moisture meter. These are relatively inexpensive and readily available. I use a Delmhorst BD-2100, which I find to be very reliable.

Why Seasoning Matters:

• Efficiency: Seasoned wood provides significantly more heat output per log.
• Safety: Burning seasoned wood reduces creosote buildup in your chimney, minimizing the risk of chimney fires.
• Environmental Impact: Seasoned wood burns cleaner, producing less smoke and particulate emissions.

Choosing the Right Wood: A Guide to Species

Not all wood is created equal. Different species have different densities, burning characteristics, and heat outputs.

• Hardwoods vs. Softwoods: Generally, hardwoods (deciduous trees like oak, maple, and ash) are denser and burn longer and hotter than softwoods (coniferous trees like pine, fir, and spruce).
• High BTU (British Thermal Units) Woods:
  • Oak: A classic choice, oak burns long and hot, producing excellent coals. It’s my personal favorite, although it can take longer to season.
  • Hickory: Similar to oak, hickory is another excellent choice for heat output and long burn times.
  • Beech: A dense hardwood that burns well and produces a pleasant aroma.
  • Maple: A good all-around choice that burns relatively clean.
• Medium BTU Woods:
  • Ash: Easier to split than oak, ash burns well and produces good heat.
  • Birch: Burns quickly but produces a good flame.
  • Cherry: Burns with a pleasant aroma and produces moderate heat.
• Low BTU Woods:
  • Pine: Burns quickly and produces a lot of smoke, making it less desirable for stove inserts. However, it can be useful for starting fires.
  • Fir: Similar to pine, fir burns quickly and produces less heat.
  • Spruce: Another softwood that’s best avoided for primary heating.

My Personal Experiences:

I’ve burned just about every type of wood imaginable over the years. I’ve found that oak provides the most consistent and reliable heat output, but it’s also the most challenging to season. Ash is a good compromise, offering decent heat and easier splitting. I generally avoid softwoods except for kindling.

A Note on Wood Availability: The best wood is the wood that’s readily available and affordable in your area. Don’t be afraid to experiment with different species to find what works best for you.

Felling the Tree: Safety First!

If you’re harvesting your own wood, felling trees is the first step. This is a potentially dangerous activity, so safety is paramount.

• Safety Gear: Always wear appropriate safety gear, including:
  • Helmet: Protects your head from falling branches.
  • Eye Protection: Safety glasses or a face shield are essential to protect your eyes from flying debris.
  • Hearing Protection: Chainsaws are loud! Wear earplugs or earmuffs to prevent hearing damage.
  • Gloves: Protect your hands and improve your grip.
  • Chainsaw Chaps: These are designed to protect your legs from chainsaw cuts.
  • Steel-Toed Boots: Protect your feet from falling logs and chainsaw accidents.
• Chainsaw Selection: Choose a chainsaw that’s appropriate for the size of the trees you’ll be felling. A chainsaw with a bar length of 18-20 inches is a good general-purpose size. I personally use a Stihl MS 271 Farm Boss for most of my felling needs. It’s powerful, reliable, and relatively lightweight.
• Felling Techniques:
  • Assess the Tree: Before you start cutting, assess the tree for lean, wind direction, and any potential hazards like dead branches or power lines.
  • Clear the Area: Clear a path around the tree so you can retreat safely.
  • The Notch: Cut a notch on the side of the tree in the direction you want it to fall. The notch should be about one-third of the tree’s diameter.
  • The Back Cut: Make a back cut on the opposite side of the tree, slightly above the notch. Leave a hinge of wood to control the fall of the tree.
  • Wedges: Use wedges to help direct the fall of the tree and prevent the saw from pinching.
  • Retreat: Once the tree starts to fall, retreat quickly and safely away from the falling tree.
• Professional Help: If you’re not comfortable felling trees yourself, hire a professional arborist. It’s better to be safe than sorry.

A Personal Story: I once had a close call when felling a tree. I misjudged the lean of the tree, and it started to fall in the wrong direction. Fortunately, I was able to retreat quickly and avoid being hit. That experience taught me the importance of careful planning and attention to detail when felling trees.

Bucking the Logs: Cutting to Length

Once the tree is on the ground, you’ll need to buck the logs into manageable lengths.

• Safety: Continue to wear all your safety gear.
• Log Length: Cut the logs to a length that’s appropriate for your stove insert. As mentioned earlier, most inserts have a maximum log length of 16-20 inches. I recommend cutting them slightly shorter than the maximum to allow for easier loading and better airflow. I typically cut my logs to 14-16 inches.
• Cutting Techniques:
  • Support the Log: Make sure the log is properly supported to prevent the saw from pinching. You can use log jacks or other supports.
  • Cut Straight: Try to cut the logs as straight as possible. This will make them easier to split and stack.
  • Avoid Cutting into the Ground: Be careful not to cut into the ground with your chainsaw. This can damage the chain and dull the saw.

Splitting the Firewood: The Art of the Wedge

Splitting firewood is a physically demanding but rewarding task.

• Tools:
  • Axe: A good splitting axe is essential. I recommend an axe with a weight of 6-8 pounds. I’ve had good luck with the Fiskars X27.
  • Splitting Maul: A splitting maul is a heavier tool that’s designed for splitting larger, tougher logs.
  • Wedges: Steel wedges can be used to split particularly stubborn logs.
  • Sledgehammer: A sledgehammer can be used to drive wedges into logs.
  • Hydraulic Log Splitter: If you’re splitting a lot of wood, a hydraulic log splitter can save you a lot of time and energy. I use a 25-ton gas-powered splitter from CountyLine, which is a real workhorse.
• Splitting Techniques:
  • Safety: Always wear safety glasses and gloves.
  • Stance: Stand with your feet shoulder-width apart and keep your back straight.
  • Aim: Aim for the center of the log or for any existing cracks.
  • Swing: Swing the axe or maul with a smooth, controlled motion.
  • Follow Through: Follow through with your swing to maximize the force.
  • Wedges: If the log is too tough to split with an axe or maul, use wedges and a sledgehammer.
• Hydraulic Log Splitter:
  • Safety: Always read and follow the manufacturer’s instructions.
  • Placement: Place the log on the splitter and position the wedge.
  • Operation: Operate the splitter according to the manufacturer’s instructions.
  • Size Limitations: Be aware of the splitter’s size limitations and don’t try to split logs that are too large.

Case Study: Using a Hydraulic Splitter for Efficiency: I recently had a project where I needed to split several cords of oak. Using a traditional axe and maul would have taken me weeks. Instead, I used my hydraulic log splitter and was able to complete the project in just a few days. The splitter significantly reduced the amount of physical labor required and allowed me to split even the toughest logs with ease.

Seasoning the Firewood: The Key to Efficient Burning

Proper seasoning is crucial for efficient and safe burning.

• Stacking: Stack the firewood in a way that allows for good air circulation.
  • Elevate the Wood: Elevate the wood off the ground using pallets or other supports. This will prevent moisture from wicking up into the wood.
  • Loose Stacking: Stack the wood loosely to allow for air circulation.
  • Orientation: Orient the wood so that the ends are exposed to the air.
  • Covering: Cover the top of the wood pile with a tarp or other waterproof material to protect it from rain and snow. Leave the sides open to allow for air circulation.
• Location: Choose a location that’s sunny and windy. This will help to speed up the drying process.
• Time: Allow the wood to season for at least six months, and preferably a year or more. The longer it seasons, the better it will burn.
• Moisture Content Testing: Use a moisture meter to check the moisture content of the wood. It should be 20% or less before burning.

My Firewood Stacking Method: I’ve developed a stacking method that maximizes air circulation and minimizes space. I stack the wood in rows, leaving a small gap between each row. I then cover the top of the pile with a tarp, leaving the sides open. This method allows for good air circulation while protecting the wood from rain and snow. I’ve also found that elevating the wood on pallets significantly reduces drying time.

Loading and Burning in Your Ember Hearth Insert

Now that you have properly seasoned firewood, it’s time to load and burn it in your Ember Hearth insert.

• Starting the Fire:
  • Kindling: Use small pieces of dry kindling to start the fire.
  • Paper: Use newspaper or other paper to help ignite the kindling.
  • Airflow: Open the air controls to provide plenty of airflow.
  • Top-Down Burning: Consider using the top-down burning method, where you place the kindling on top of the larger logs. This method produces less smoke and burns more efficiently.
• Loading the Wood:
  • Placement: Place the logs in the firebox so that they’re not touching the sides or the door.
  • Airflow: Leave space between the logs to allow for airflow.
  • Overloading: Avoid overloading the firebox.
• Air Controls: Adjust the air controls to maintain a steady, efficient burn.
• Monitoring: Monitor the fire and adjust the air controls as needed.
• Ash Removal: Remove the ashes regularly to maintain good airflow and prevent creosote buildup.

Maintenance and Safety: Protecting Your Investment

Proper maintenance and safety are essential for the long-term performance of your Ember Hearth insert and the safety of your home.
