How do I choose the size of fireplace?

Too large can cause problems just as too small can. A stove that’s too small will not be able to heat the room adequately. However, if you buy a stove that’s too big in relation to the room, you will continuously have to cut the air supply to keep the room temperature down. This can cause damage to the fireplace just as much as over burning the fireplace. For most South African houses that have poor insulation work on 10m² per kilowatt output.
