A heat pump works like an A/C unit in reverse. It takes heat from the outside air and moves it to inside the house. It works well when outdoor temps are about 40 degrees and above. A furnace is inside the house and it actually makes its own heat and circulates it thru the house. Heat pumps are usually in homes that only have electricity, no natural gas available. We had them in Maryland where the winters are not tremendously cold. The only thing is the air that comes out of the heat vents doesnt really feel warm. The electric furnace inside the home takes over when the outside temp falls too low to get any heat out of the air. I would think they should work well here in florida with our easy winters. It does put added wear and tear on your outside compressor unit though.
