That condensation is releasing 970 BTUs of heat per pound of water to 
the outside as it condenses.  In addition to the 1 BTU per degree of 
temperature difference (per pound of water).  All of which needs to be 
added to the convective heat loss from the air movement.

You are using the energy in the house to power a heat cycle which is 
pumping heat to the windows, and beyond.


Thank You Kindly,
