Here’s what to know when buying the perfect closed combustion fireplace for your home. Closed combustion refers to a fire burning behind a sealed glass door fitted with adjustable air controls which regulate the amount of air flowing into the combustion chamber.
These air controls allow the user to regulate the combustion air and thus adjust the output of the fireplace. In an open combustion fireplace there is no control over combustion air, thus accelerating the combustion air intake as the temperature in the fireplace increases, resulting in heat loss through the flue outlet.
Unlike an open fire, a closed combustion fireplace is highly efficient and very economical. They use approximately a 3rd of the wood (compared to an open fire) and transfer up to 85% of the heat back into the room rather than losing the heat through the flue outlet. They also produce less ash and lower carbon emissions. Closed systems are safe as the glass prevents any smoke or other combustion gases coming into the room –So no smoky smells in your home or on your clothes!
