Just purchase 1880 home from parents estate. Noticed stain on ceiling on second floor near chimney. Called "Chimney Sweep Co." to give me a diagnosis and estimate. Chimney needs complete rebuild from roof up. This includes new lead around the base etc. I agree with this.
Having a heating system installed in the near future and will need a liner,
(vent) for the natural gas water heater only. New gas furnace will vent to the outside through house wall.
My heating system guy tells me 3 inch aluminum vent pipe will work fine.
"Chimney Sweep Co. which has proper license to do the liner tells me that aluminum will only last 10 years.
They recommend using stainless - life time use. Cost for stainless 3" is just shy of one thousand dollars. I realize stainless is expensive but...
I am wondering if it is still ok to go with the aluminum as we will be only venting one gas water heater.
