I have a Hearthstone Heritage as well. Been burning with it for 7 years , great stove , heats the whole house , and burns very little wood compared to those old stoves. I heat 1800 square feet 24/7 and on a normal winter in mid michigan I use about 2-3 cords. I will say this , you must use well seasoned wood . I'm a good 8 years ahead so don't think you can fell an oak in the spring and burn it that winter. It won't work.
These have combustion tubes on top, no blower , but when the stove is up to temp it looks like a gas flame shooting out and no smoke outside at all.
I wouldn't hesitate buying a Woodstock stove, friend has one and is a great stove. He gets some longer burner times with the cat. I believe Woodstock is making a hybrid stove as well, maybe take a look ?
