Noncondensing furnaces are less efficient than condensing furnaces at extracting heat from the exhaust gases produced by the furnace. This lowers their overall efficiency, as this non-extracted heat escapes out of the building. As a side effect, noncondensing furnaces need to be vented through a chimney, since the exhaust gases are often very hot.
