I got some quotes to either remove my chimney down to the roof line, B vent it or reline.

The chimney only serves a water heater and Im not super enthusiastic about buying a new power vented 1 since its 7 years old.

The costs:

B vent $4500

Removal $ 2400 + (needing a new water heater)

Reline $1800

From what I can tell the masonry is solid so im not even sure why a B vent would be needed other than to make the other 2 options seem more palatable? Is there a reason anybody would pick a B vent? The price for that seems outrageous.
