I'll also comment here... we have had the Nova 1 for a bit less than a year now, and have probably burned about a cord and a half in it.
This has been our first winter burning, and I'm very happy with the stove so far. Fuel is a mix of about a cord of ash from a tree felled May 2021, and two cords "seasoned hardwood" (read: cut/split 6 months prior but sitting in a pile in the rain all summer, and we had two feet of rain here last summer) that I got and stacked in early September. Obviously this is far from ideally seasoned wood, but we have some good garage storage space that accelerated the drying, a fast draft on the chimney, AND (for us; clearly not for nova 2 owner!) this stove seems to burn marginal wood like a champ. Got a mid-season sweeping in late December and we were in great shape, with very little buildup (I was rather concerned given that we'd gone through about a cord of wood).
Biggest downside is that our fast draft + lack of air control + relatively small firebox on the Nova 1 mean that I'm reloading a lot. Full loads get the stove very hot (not overfired, but I don't want to chance it...). I can get coals to relight on in the morning if I load up full overnight but this wastes a lot of heat and it's still not much of a coal bed to start on, and we are wood-limited this winter so I don't want to waste heat when we're not in the room. (I'm also reloading pretty hot since wood this winter is not as dry as I'd like, so that's a contributor to this con that's not about the stove)
So anyhow, TL;DR:
Pros: Great stove overall: gorgeous simple design, nice big glass viewing door (for us it stays really clean), **clean burning on suboptimal wood**, very simple operation.
Cons: More reloading than I'd like, runs a shade hot on full loads, no air control to prolong burns.
(Note: We're heating a ~2200 square foot house, and this stove is rated for considerably less than that, so some of these cons may be more about stove sizing than about the stove itself. This was a compromise... because of the location of the stove and floor plan of the house, it wasn't feasible to get a much bigger stove to heat the whole house; it would bake us out of our living room!)
