Hardwood is generally denser than softwood. Hardwood is also heavier than softwood. But what does that translate to in heating a home? Apart from aesthetic differences, Hardwood because of its nature burns slower, perhaps slightly less hotter than softwood. Therefore, your burning time of Hardwood will be longer meaning fewer refills required. Softwood on the other hand, burns quickly producing slightly greater heat. However, it’s easier to light softwood and it helps get the temperature up quickly.
