I received a bid to line an old chimney for 2 55,000 btu furnaces, and 2 30 gallon water heaters, two liners would be needed due to the small size of the chimney chases. (the chimney is split into two chambers, so each too small to do 1 liner for all four items. The bid included the use of 306 stainless steel or a second price for aluminum. The aluminum is a lot cheaper than the stainless, as expected. I asked the bidder about the life of the aluminum versus the stainless and all he said was stainless is lifetime, aluminum is 15 years from the manufacturer, 1 year warranty on labor for both. Seems the low levels of nitrogen oxides in natural gas fumes would not affect the aluminum too much, so what is everyones opinion on the life span of aluminum? Are there any other better alternatives than these two metals?
