In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
I recently had a buderus g115-ws installed. There were signs of condensation in the chimney, so the installer removed the last baffle (mustache). The other 2 baffles had been removed before the install b/c I didn't have a SS liner. Now my options are to run it without any baffles, or I could line the chimney and run it with all 3 baffles. Does anyone have an estimate of the difference in efficiency between the 2 options? Regardless of efficiency I am leaning towards just lining the chimney, but I was wondering if the efficiency gain would cover the cost of the liner. Thanks in advance
