Glad I found this forum. Just bought a Vermont Castings Encore Defiant wood stove. I would like to put it up stairs in living room but I am concerned of the weight of the hearth and stove sitting on joists. Hope that I am not bothering anyone with this as it was probably asked already. The joists are 2 x 10 16 on center about 13 feet long. The stove will sit about in the middle and the hearth I want to build will cover 3 joists. I guess the question is how much weight will it hold and how thick does the hearth have to be? Thank you for you help.
