Fireplaces have come a long way in the last 20 years. We went from open hearths to convection open fireplaces and now slow combustion fireplaces.

What are the advantages of slow combustion fireplaces vs open fireplaces :

  • With an open fireplace the fire draws as much oxygen as it requires to burn at its maximum rate and consumes large amounts of wood. With slow combustion fireplaces, you control the amount of oxygen to the fire and thus the speed at which it burns. As a result, slow combustion fireplaces are more efficient and consume about a sixth of the amount of wood compared to an open fireplace.
  • An open fireplace draws hot air out of a room while not in use and only delivers heat when in use. With slow combustion fireplaces there is no heat loss out of the room while not in use due to the fact that it’s a closed system.
  • The inefficiency of open fireplaces is well known as approximately only 20-25% of heat generated comes back into the room.  With slow combustion fireplaces this ratio is the exact opposite. Some brands such as Carbel feature a double baffle system which produces up to 80% efficiency.
  • Open fireplaces have a tendency to make the room smell smoky. During the warmer months when the seasons change, the outdoor temperature is higher than inside the house. As a result the air flows through the chimney from a high pressure to a low pressure, bringing with it the smell of the soot inside the chimney. With a closed system this won’t happen.

So why not convert your smelly inefficient open fireplace to a slow combustion fireplace?
