The size of woodburner you buy for your room is very important. You don't want to have to sit in your front room in your swimming shorts and a bikini!
The size of your wood-burning stove depends on the size of the area you wish to heat. A stove that is too large can cause just as many problems as a stove that is too small. A stove that’s too small will not be able to heat the room adequately.
If you buy a stove that's too big in relation to the room, you will be forever cutting the air supply to keep the room temperature down.
As a result, combustion will be incomplete and soot will quickly build up on the stove window and in the chimney. In addition, the quantity of soot particles you emit into the environment will be disproportionately high.
