You can see from my sig. That I am in SW Fla. This winter we are full timing having sold the house. Years ago I snow birded in Sarasota. We will use our two heat pumps and fire place unless it falls into the 30's which only last for a few hours here in SW Fla. We are also lucky to have insulated windows and well insulted unit. Buy early morning the sun is out and heating up nicely. We pay for electric but then it is still a whole lot cheaper then heating that house we had. It just comes down to what price you put on comfort.
