Question: My husband and I rent a historic cottage which has a beautiful, but old stone fireplace. We have a wood stove for heat and need to line the chimney with stainless steel flex pipe. My husband found some of this pipe, this particular kind rated for up to 1400 degrees F., for a great price of $4.79 per foot. We are concerned that it is safe for lining the chimney, since the estimates we got from stove stores and chimney cleaners was much higher...$30 per foot. Answer: The chimney sweeps could have been talking about flexible pipe...or about an instlaled price which is much higher than the material cost. There are also many different grades and thicknesses of stainless steel single wall pipe. The price you got sounds like a "wholesale to the public" cost, which is surely attractive if the material is rated for your job.
