Do your bit for the environment. Burning logs does produce carbon, but if you buy from sustainable sources where replanting takes place then the whole process becomes Carbon Neutral. This is only possible if you buy locally sourced and sustainable wood rather than using imported wood from places such as Eastern Europe.
The main advantage of using hardwood rather than softwood is that you need less logs to produce the same amount of heat. Hardwoods provide a cleaner burn than softwoods and do not produce toxic tars that can be corrosive and dirty. Unlike softwoods, hardwoods do not ‘spark’ in open fires.
