The 905 WN is a wood cooker designed for today’s kitchen: clean burning and easy to use. In simple terms, you could load the firebox in the morning and just place some extra fuel on before cooking dinner. Another load before you go to bed would keep it burning until morning, giving the potential to keep the fire going for several days or even weeks at a time. Ash removal is necessary, but with good quality fuel this might only be once a month. The 905 is quickly back up to cooking temperature, even from cold.
