Efficient wood burning stoves from Quadra-Fire are the wood heater of the future in Australia. Unlike traditional catalytic stoves, Quadra-Fire stoves are cleaner and more fuel efficient than any of their competitors. For nearly two decades, Quadra-Fire stoves have been tested by the EPA and each year have been found to be the cleanest burning non-catalytic wood stoves on the Australian market. Each Quadra-Fire stove offers the highest efficiency of any wood fireplace and because it is non-catalytic, the system does not degrade in performance over time. Thanks to its patented Quadra-Burn system, all Quadra-Fire stoves offer customers an efficiency of 79 to 82% – compared to an industry average of 55%.
