Frequently Asked Questions
What is a BTU and why does it matter for firewood?
BTU (British Thermal Unit) measures heat energy. Denser hardwoods like oak and hickory have higher BTU ratings per cord than softer woods like pine.
Does stove efficiency really affect cost?
Yes, an inefficient stove or fireplace can waste 30-60% of the wood's heat energy up the chimney, effectively raising your true cost per BTU.
How many cords do I need for a winter?
This depends on climate, home size, and insulation, but many homes in cold climates use 3-6 cords per heating season.
