That might have made sense to them at the time.  (-:

That makes NO SENSE.

Nor does this.
 
BA> When I installed a new furnace in my former house they ran an ordinary

BA> Barely warm air and lots of water vapor is all that comes out of it,

And now the heat is staying in the house rather than going up the chimney?
