Find Firewood in Your State
FAQs
Technically you can burn green wood, but you absolutely shouldn’t. Green or unseasoned wood contains 50-60% moisture content, making it one of the worst fuel choices for any fire. The problems created by burning wet wood far outweigh any perceived benefit of using wood before it’s properly seasoned.
When you attempt to burn green wood, much of the fire’s energy goes toward evaporating water rather than producing heat. This means you get minimal warmth despite consuming wood. The fire smolders and struggles to maintain temperature, requiring constant attention and frequent relighting. A significant portion of your wood literally goes up in smoke rather than providing useful heat.
Creosote buildup represents the most serious danger. Green wood produces excessive smoke containing unburned particles that condense as creosote—a flammable, tar-like substance—inside your chimney. Creosote accumulation significantly increases chimney fire risk, a dangerous and potentially catastrophic event. Professional chimney cleaning becomes necessary far more frequently when burning green wood.
Environmental and health impacts are also concerning. Green wood creates heavy smoke pollution, releasing more particulates and carbon monoxide into the air. This affects both indoor and outdoor air quality, potentially causing respiratory irritation and contributing to regional air pollution.
The false economy of burning green wood becomes apparent quickly. While you might save money upfront by buying cheaper unseasoned wood or cutting your own, you’ll spend more on chimney cleaning, use more wood for less heat, and risk expensive chimney repairs or fire damage. The math never works in favor of burning green wood.
If you have green wood, stack it properly in a sunny, well-ventilated location and wait. Six to twelve months of patience yields safe, efficient fuel. There are no shortcuts worth taking when it comes to firewood moisture content.
