Long story short: new furnace in an older house. Heavy condensation coming thru the brick and plaster chimney. I’m having a aluminum chimney liner put in as well as B Vent double walled exhaust vent in the basement.
My question is this. Once the liner is installed where does the condensation inside the chimney liner go?? It seems to me it would drip back down to to the furnace. My chimney contractor could not answer this question.
Any thoughts?

IF, the chimney is correctly sized, IF the furnace is designed to vent through a chimney and IF it's an inside chimney, there won't be any condensation. Your old chimney was to large causing the flue gasses to cool and condense. Be sure the new chimney is properly sized. Bigger is not better.
Yesterday I couldn't even spell plumber, today I are one.
VtMike,
Yeah the chimney was not lined at all. Chimney guy is going to install a 5" alluminum flexible liner. Since the furnace is about 12' from the chimney he also recommended I install 5" B vent to keep the exhaust from cooling too quickly before it reaches the chimney.
Of course I did ask the furnace installer if a chimney liner was needed. He told me not to worry about it. I suspect he did not want to do it because our chimney is over 30' tall and he did not have a long enough ladder.
So once again I end up spending more time fixing a contractor's screw up then if I would have done the job myself.
