1. What is BTU Calculation for Wood?

BTU (British Thermal Unit) calculation for wood measures the energy content in a cord of wood. It helps determine heating efficiency and compare different wood types.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Cord \) — Amount of wood in cords
• \( Avg\ BTU\ per\ cord \) — Average energy content per cord of wood

Explanation: The equation multiplies the volume of wood by its energy density to determine total available energy.

3. Importance of BTU Calculation

Details: Knowing the BTU content helps estimate heating capacity, compare fuel sources, and plan wood purchases for heating needs.

4. Using the Calculator

Tips: Enter cord amount (standard cord is 128 cubic feet) and average BTU per cord (varies by wood species). Common values range from 12-24 million BTU per cord.

5. Frequently Asked Questions (FAQ)

Q1: What's a standard cord measurement?
A: A standard cord is 128 cubic feet of wood, typically stacked as 4' x 4' x 8'.

Q2: How do BTUs vary by wood type?
A: Dense hardwoods (oak, hickory) have higher BTU content than softwoods (pine, fir).

Q3: Does moisture content affect BTUs?
A: Yes, wet wood has lower effective BTU as energy is used to evaporate water. Seasoned wood burns more efficiently.

Q4: How many BTUs are needed to heat a house?
A: Depends on climate and insulation, but roughly 20-40 million BTUs per winter for average homes.

Q5: Can I use this for wood pellets?
A: No, pellets are measured differently (typically by weight). Use a pellet-specific BTU calculator.
