ARE NOT SAFE. DO NOT BURN GARBAGE.
The quality of your firewood affects heat output,
duration of burn and performance of your Fireplace
Insert. Softwoods generally burn hotter and faster,
while hardwoods burn longer and produce more long
lasting coals. Density and moisture content are two
critical factors to consider when purchasing wood for
your Fireplace Insert.
The following is a list of wood species and their
relative BTU (British Thermal Unit) content.
higher the BTU content the longer the burn.
Firewood with higher a BTU content is generally
considered ideal for a wood stove.
