I'm wondering if it's alright to use a used stove pipe and chimney. It's from a stove that was installed in 1990. I assume the pipe is the same age. It's a GSW model SC chimney type HT according to the UL sticker, which is still present. It looks to be in good shape, though I'm no expert. I've heard that to purchase new chimney pipe would be very expensive. This I could probably pick up for very little. But I wouldn't want to do so unless it was safe. Would it be worth bringing to a chimney sweep? The one stove installer I spoke to was very reluctant to use anything used. The impression I got was he's worried about potential liability. The stove pipe looks to be about the length I would need for my home. I've got a 9 foot ceiling inside the house, same as the one it was removed from, and then it transitions from black to shiny metal color and extends up about a full story. I don't know how much new stove pipe costs, though I would imagine it's not cheap. I'm wondering what those who are experienced with stoves think. Best to just buy new or might it be worth taking this pipe to someone to be checked out carefully?
