CleanFire Series Q&A

WoodMaster certified furnaces top the EPA Cord Wood Database for Overall Efficiency. This Overall Efficiency can be as high as 84% but depending on Heat Delivery rates, the efficiency can be up to 86% Higher Heating Value and 93% Lower Heating Value. Lower Heating Value is the preferred measurement in Europe.

Pushing the air through the firebox keeps the fan clean and eliminates time consuming and costly combustion fan repairs.

The Clean Reload feature puts the furnace in idle mode about 30 minutes before your planned reloading. This helps reduce smoke when you open the firebox door to add wood.

The heat exchanger can be easily inspected with the hinged rear door. When needed, simply remove the tension-fit turbulators and run the provided cleaning tools through the heat exchanger ripples.

With the smaller firebox, a bypass is unnecessary. This model has passed the safety listing without the bypass.

Easy Refire reserves enough wood in the firebox to help quickly and efficiently ignite the new wood load.
