Questions from an absolute (urban-dwelling) newbie. Really, really, REALLY wanting something along the line of this rocket mass heater for my small den, in place of the existing freestanding gas stove. It would need to heat the den, the small kitchen (no wall between the rooms) and the adjoining small office.
Would I need to get a permit from the Powers That Be? Do permits for such even exist? I'm in lovely Fresno, CA
What might happen if I didn't bother to get one?
