I know there are times when this is ok and when it isn't ok. Currently, both run seperately to my chimney stack and the chimeny isn't lined. I want to move my gas hot water heater to a different location and it'd be much easier to then duct into the vent that feeds the furnace, but I want to insure it is ok to do. I believe I asked a housing inspector once and that he said it was ok, but it's been a while and I want to double check.
My water heater is atmospheric-vent, the furnace appears to have a small blower on it's vent, it is about a 7-8yr old unit if that makes a difference. The water heater is currently a piece of crap wirlpool, but when the move is made will probably be replaced with a Bradford White unit. I can provide exact model if need be for the furnace and the water heater.
Once I make the change, I plan on adding a flexible stainless steel (?) liner to the chimney that will terminate the top of the chimney. I could run them seperate, but then I'd have to run two liners out of the chimney, but prefer a single liner for now to allow room to possibly add a gas fireplace to my firebox and would need the remaining room for that liner!
Thanks for any feedback...
