My chimney is old and I just got a new high efficient furnace which is causing effloressence to come through the chimney walls - I need a chimney liner. I want to know why they pour insulation mix top to bottom in the chimney after installing the liner.

No, generally they will pull the liner and will hook the appliance to it including the water heater, most 82% eff. furnaces require a liner because the condensation they produce is acidic, about like orange juice and this will attack the morter in the chimney, no insulation is required.

did you verify to be certain that a 4 in. pipe is huge sufficient...maximum of todays timber stoves are so air tight and damped down that insulated flues are necessary to maintain the stack heat and to assist decelerate the formation of creosote...this suggestion got here from a range producer ...i only outfitted a brick chimney with a clay liner and grow to learn by employing the range broking to insulate around the flue with zonolite...

effloressence is water passing thru masonry carring salts
you have a water problem,.... caused by the furnace?
do you have a chimney cap?

hot air rises...they insulate to keep the stack warmer to keep a better flow...
