Purchased the HT2000 to replace an older stove. The HT2000 has unbelievable heat output. It is super easy to operate, easy to load and burns wood to a very fine ash. This stove leaves no unburned coals in the morning even whit the draft control set on the lowest setting. Burn times are 9-10 hours on a full load and leaves enough red coals to restart the burn cycle. I have been burning wood for most of my life and the HT2000 is the best stove u have ever had. The HT2000 is a very well built unit and the optional blower is very quite and worth every penny.
