Firewood is not cheap to buy. Currently people in the South are paying about $50/square metre. Therefore it is a matter of economic importance to find out what wood gives the best heat for value. It is generally accepted that various woods have different burning characteristics and also that moisture content of that wood is a major factor in burning and heat efficiency. As long as the wood being burned in the fire is totally dry and burns hot the actual type of wood to be burned is the next problem to be faced. Macrocarpa, gum, sycamore and manuka are highdensity hardwoods that burn long and hot. These are among the most expensive to buy. Before ordering any of these woods check that the wood being delivered to you has been thoroughly seasoned.
