The right thing to do is to put the hot end of the refrigeration coils
outside the building if possible -- not to shoot yourself in the foot
by heating a room that you have to cool. Of course, you then face
increased energy costs from an increased differential between the
target temperature and the temperature outside the chamber, but at
least you aren't facing the far greater inefficiencies of pumping heat
