Our older Regency doesn't seem to be getting hot enough. My experience with wood stoves is all prior to 1990. Wood is dry maple, beech or ash, 3 years old and split. With a stovepipe thermometer on top of the stove itself I have trouble getting to 600+ with the draft wide open. I know the "newer" style stoves aren't supposed to get as hot as what I used to have but is that hot enough? Thank you
