Found this difficult to get going but when going produces a lot of heat. The air adjustment, though, has a ridiculously small range of movement; effectively, it's either full on or full off! We also have a Chesney Salisbury. Nnot as good looking but easier to light and adjust.
Ok, thanks for the answer. I guess that this bimetallic spring helps to improve air flow and, finally wood combustion so you should notice a low wood consumption and a stove glass that stays longer clean. Sounds a good system
