I haven't been in the market for a wood stove in years, so I haven't been paying attention to new features. Is this new Hearthstone Heritage hybrid a cat stove now? Are the burn times for real? 25 hours sounds a bit extreme, so I'm wondering what the true numbers are. It was already a great stove. With the side door now opening down instead of regular, I wish I had the $$ to upgrade. I can't imagine that sucker is cheap.
