Just wondering how big the firebox is in the Oslo?2.67 cu ft in the Rangeley.Supposed to be 10% overall more efficient than the Oslo but rates the same 70.000 btu and 2000 sq ft heating area.The Oslo lists 9 hr burn and the Rangeley lists 8+ and i have gotten 9 so far.We all know that listings are no better than our own findings.The Oslo sure looks better.Just kinda comparing,burning time as well as wood.
) I would find members like you getting 8-10 hours or heat production and then others getting far less. I was concerned I was't going to get much longer burns than what the Vigilant and the Heritage gave me. In the end I think I made the right call. I have plenty of heat with my current set up, now I just need to tweak things and go cat with all three stoves.
