Three years ago I bought a wood burning insert for my fireplace and am using it as my primary heat source in the winter. It works great, but I am wondering if I can make it more efficient. There is about a foot of open space behind the stove, as well as open space on either side of the 6 inch S.S. liner going through the flue. Is there a material I can fill these gaps and spaces with? What are some of you guys doing, if anything???? Maybe I am putting too much thought into this, but seems like a lot of heat is being lost up the chimney.
