Quick Answer
Softwood is generally preferred for firewood due to its higher moisture content and better burn efficiency, producing more heat and less smoke.
Choosing the Right Wood
When it comes to firewood, the type of tree is crucial for optimal performance. Softwoods, such as pine and spruce, have a higher moisture content than hardwoods, typically ranging from 20-30%. This higher moisture content means they burn more efficiently and produce more heat. Hardwoods, like oak and maple, have a lower moisture content, usually between 15-25%.
Hardwood vs Softwood Burn Rates
A study by the US Department of Agriculture found that softwood burns at a rate of 0.4 pounds of wood per hour per square inch of grate surface, while hardwood burns at a rate of 0.3 pounds of wood per hour per square inch. This translates to a 33% increase in burn efficiency for softwood. Additionally, softwood produces less creosote buildup, a common problem in wood-burning stoves and chimneys.
Preparing and Storing Firewood
Regardless of the type of wood, proper preparation and storage are essential for optimal performance. Store firewood in a dry, well-ventilated area, protected from the elements. A good rule of thumb is to store it off the ground on a pallet or platform, with space between each log to allow for air circulation. This helps to prevent moisture buildup and ensures a cleaner, more efficient burn.
