Introduction:
Understanding the measurements of firewood is crucial for efficient and cost-effective use in wood burning stoves. One common term you’ll encounter is the "face cord." In this article, we’ll break down the technical details of face cord measurement, helping both technical and non-technical audiences grasp this essential aspect of wood stove operation.
Definition of Face Cord:
A face cord is a unit of measurement for stacked firewood. It is typically 4 feet high and 8 feet long, with the depth of the stack varying based on the length of the logs. Standard firewood lengths are 16 inches, so a face cord would consist of three rows of logs, each 16 inches long.Volume and Capacity:
The volume of a face cord can vary, as it depends on the length of the logs. For instance, a face cord of 16-inch logs will have a different volume than one with 24-inch logs. It’s important to be aware of the specific length of the firewood when purchasing or measuring a face cord to accurately estimate the amount of wood you’re getting.Understanding the Difference from Full Cord:
It’s essential to differentiate between a face cord and a full cord. A full cord is a stack of wood that measures 4 feet high, 4 feet wide, and 8 feet long, totaling 128 cubic feet. In contrast, a face cord lacks the depth of a full cord, consisting of only one stack face, making it a third of a full cord.Calculating Energy Content:
The energy content of firewood is measured in British Thermal Units (BTUs). The type of wood and its moisture content influence the BTU output. A seasoned hardwood face cord will generally provide more heat than a softwood face cord. Consider these factors when assessing the efficiency and heat output of your wood burning stove.Seasoning and Moisture Content:
Seasoned firewood has been allowed to dry for an extended period, reducing its moisture content. Well-seasoned wood is essential for efficient combustion in wood stoves. Aim for a moisture content of around 20% for optimal performance, as wet or green wood can produce more smoke, less heat, and contribute to creosote buildup in the chimney.Buying Tips:
When purchasing a face cord of wood, ask about the specific length of the logs and whether the wood is seasoned. Knowing these details will help you make an informed decision, ensuring you get the right amount of quality firewood for your wood burning stove.
Conclusion:
In the world of wood burning stoves, understanding face cord measurement is a practical skill that ensures you get the most value and efficiency from your firewood. Whether you’re a seasoned stove user or a newcomer, grasping the basics of face cords empowers you to make informed decisions about the quantity and quality of wood fuel for your wood burning stove, contributing to a warm and cozy home during the colder months.
