This is a 5" chimney pipe that goes right up through the center of the
house. Maybe running a 3" aluminum pipe inside it would be a good
idea? I am also wondering about the acceptable amount of offset in the
basement -- as I don't really want to position the water heater
directly under the chimney pipe, but would prefer to have it several
feet over.

The water heater here vents into an old masonry chimney w/ a horizontal
run from the exit elbow into the chimney w/ no problems.

5 inch chimney is likely too big.........

draw will be poor because the water heaters exhaust wouldnt heat up
the chimney enough

It's not been an issue w/ an 8" square here in 60-some years.
