Hello, I have a gas hot water heater and furnace. They simply exhaust into the brick chimney that is terra-cotta lined. I'm having moisture issues with water dripping from the mortar joints in the cold attic. I'd like to run a liner up my chimney from my gas appliances.
My furnace is 100,000 BTU 80% efficiency. My hot water heater is 40,000 BTUs. I'm under the impression I would need a 5" liner, but then they also sell a 6".
