One of the most compelling reasons to consider a G7000 is its impressive efficiency. These boilers are designed to burn wood cleanly and completely, extracting a high percentage of the fuel’s energy as heat.

Combustion Technology: The G7000 typically employs gasification technology. This means the wood is heated in a low-oxygen environment, releasing gases that are then burned in a secondary combustion chamber. This two-stage process results in a more complete burn, reducing emissions and maximizing heat output.
Reduced Wood Consumption: Because of their efficiency, G7000 boilers require significantly less wood compared to traditional wood stoves or older boiler models. I’ve observed savings of up to 50% in wood consumption in some cases, which translates to substantial cost savings over the long term.
Real-World Example: I once helped a friend replace his old wood stove with a G7000. He was using roughly 8 cords of wood per winter. After the switch, he was down to around 4 cords, a huge difference! This not only saved him money but also reduced the amount of time he spent cutting, splitting, and stacking firewood.

2. Environmental Friendliness

In today’s world, environmental responsibility is paramount. The G7000 wood boiler offers a greener heating solution compared to fossil fuels.

Reduced Emissions: The advanced combustion technology in G7000 boilers significantly reduces emissions of harmful pollutants like particulate matter, carbon monoxide, and volatile organic compounds (VOCs). This is crucial for protecting air quality and minimizing your environmental impact.

1. Use Properly Seasoned Wood

This is perhaps the most crucial factor in achieving efficient wood boiler heating. Seasoned wood burns hotter, cleaner, and more efficiently than green wood.

Moisture Content: Green wood can have a moisture content of 50% or higher. This means that a significant portion of the energy from the fire is used to evaporate the water in the wood, rather than heating your home. Ideally, you want to use wood with a moisture content of 20% or less.
Seasoning Process: To properly season wood, you need to split it and stack it in a well-ventilated area, away from direct rain or snow. The seasoning process can take anywhere from 6 months to 2 years, depending on the type of wood and the climate.
Wood Species: Hardwoods like oak, maple, and ash are generally preferred for wood boilers because they have a higher energy density than softwoods like pine and fir. However, softwoods can still be used, but you’ll need to burn more of them to achieve the same heat output.
Measuring Moisture Content: I use a moisture meter to check the moisture content of my firewood before burning it. These meters are relatively inexpensive and can save you a lot of time and frustration in the long run. Aim for a reading of 15-20% for optimal burning.
My Experience: I once tried to burn some wood that I thought was seasoned, but it turned out to be too wet. The fire was smoky, inefficient, and produced very little heat. I learned my lesson the hard way and now always make sure my wood is properly seasoned before burning it.

2. Optimize Airflow and Draft

Proper airflow is essential for efficient combustion in a wood boiler. The G7000 is designed with specific airflow settings to optimize the burning process.

Air Inlet Adjustments: Most G7000 models have adjustable air inlets that allow you to control the amount of air entering the combustion chamber. Experiment with different settings to find the optimal balance for your specific wood type and burning conditions.
Chimney Draft: The chimney draft is the force that pulls air through the boiler and out the chimney. A strong draft is essential for efficient combustion. Make sure your chimney is properly sized and free from obstructions.
Chimney Height: The height of your chimney can significantly affect the draft. A taller chimney will generally produce a stronger draft. Consult the G7000’s manual for the recommended chimney height.
Barometric Damper: A barometric damper can help regulate the draft in your chimney, preventing it from becoming too strong or too weak. This can improve combustion efficiency and reduce creosote buildup.
Cleaning the Chimney: Regular chimney cleaning is essential to maintain proper draft and prevent chimney fires. Creosote buildup can restrict airflow and increase the risk of a fire. I recommend having your chimney inspected and cleaned at least once a year.
