I have a traditional brick chimney which I no longer
use as I have switched to a high efficiency propane
furnace (so the smoke goes out through a small pipe).
Any estimates of how much heat loss I am having
(brick having a low R-value) and what I should about
it? (I don't think I have the energy to remove it).
