While the large mass cob type heater is undoubtedly efficient, for many people it requires quite a re-work of their home, and they may not want that. However, a more radiant and less massy heater which can "drop in" in place of a regular wood stove might be more popular.
Interested about the comments about steel not coping well with the temperatures, though. Is that about thickness of the steel tube, or is any steel tube gonna fail prematurely?
