Some experience with Regency 1100s
We have two of the Regency 1100 stoves. One is twenty years old, lights and drafts very easily, and is very basic. The other, more recently purchased, is equipped with all options, ash cleanout, blower, heat shields.
The older, basic stove is mostly radiant and sits in the open, the latter stove with it's heat shields and blower is much more convective and sits in a old fireplace alcove originally designed for cooking and clothes washing.
Obviously we have had good experience with the stove.
The wood has to cut small, 16 inches is great, 18 inch wood requires working through the door.
Like any small stove that is always run hot, you do not have many chimney problems. These stoves, to our experience, are absolutely reliable and burn anything, even less than dry wood. They do not have catalysts and smoke only briefly on firing up. They are easy to take apart and clean. The air inlet is right in front of the glass, so you always have a beautiful flame to look at.
Gripes: On the last purchased unit the door is priced separately, the fire box is still small and will not hold a fire over night, and if you shut off the air supply to limit the burn, the glass in the door will smoke up. The door is easy to clean with oven cleaner, but still an irritation.
Our radiant model is in a 700 square foot glorified fishing shack, the later one heats a 1300 square foot two store renovated log farmhouse, both are very well insulated. Both are pedestal models using outside air.
Good dealers to work with both times.
Hope this helps
