What type of wood is noted for generally having more BTU per cord?

Hardwoods are noted for generally having more BTU (British Thermal Units) per cord compared to softwoods. This higher energy content in hardwoods is due to their denser structure, which allows them to store more energy in the form of heat when burned. As hardwood species typically have a higher specific gravity, they burn longer and produce more heat energy than softwoods, making them a preferred choice for heating purposes.

Softwoods, although they ignite quickly and are often easier to split, typically have a lower BTU output. Living trees are not a suitable choice for measuring BTU since they have moisture content that prevents efficient burning, and green wood, which refers to freshly cut wood with high moisture content, also does not generate effective heat until it has been properly seasoned and dried. Consequently, for those seeking maximum heating efficiency, using seasoned hardwood is the best option.
