Finally, an efficient wood burning stove that doesn’t cause a mess every time you use it! Quadra-Fire fireplaces and stoves use the patented Quadra-Burn system that burns and re-burns gases and smoke in four different zones of the firebox, technology that saves money and reduces environmental impact. The average rate of efficiency in this wood burning stove heater is over 80% repeatedly beating out its Australian competitors who barely manage only 55%. Whether you’re starting a fire from scratch or maintaining one, Quadra-Fire fireplaces are simple to use and mess free. The product’s Clear View and Quaternary Burn System keep the Quadra Fire’s glass clean and eliminate impurities before they exit the chimney.
