Kiln Dried Hardwood Logs are a popular choice with wood burning stove owners and people with open fireplaces.
Drying wood before burning reduces the amount of moisture in the wood.
Moisture affects the burning process, with unburnt hydrocarbons ( and heat potential) going up the chimney and causing build up of creosote and tar in the chimney flue .
It is these deposits that need to be cleaned by regular chimney sweeping to maintain the stove efficiency.
