Quadra-Fire wood heaters provide freestanding solid-fuel options across several body sizes, including 31LE, WS18, WS22, 4300 Millennium, 5700 Step Top and Encore. The useful comparison is how much heating demand the home has, how large a firebox and footprint the room can accommodate, and which styling best suits the space.
The 4300 Millennium and 5700 Step Top are the clearest size step-up within the family. The 5700 is the larger high-capacity stove and is intended for substantial heating demand, while the 4300 offers a smaller body and firebox for projects that do not need the largest model. Use the Australian-certified specification for the exact appliance when comparing heating guidance, efficiency, emissions and clearances.
The 31LE, WS18, WS22 and Encore broaden the range with different proportions and body styles. These models should be compared on firebox volume, permitted log length, door and viewing area, overall dimensions and any available fan equipment rather than assuming all Quadra-Fire heaters share the same performance.
Size a wood heater with a heat-loss assessment that considers climate, insulation, ceiling height, glazing and connected spaces. A qualified installer should confirm hearth protection, rear and side clearances, flue design and local installation requirements.
Use dry, seasoned wood and follow the owner and installation manuals for loading and operation. If two models suit the heating requirement, choose between them using the room footprint, desired viewing area, wood-storage routine and how much heat you need during typical winter use.
