Well, I did it! I went one step further though and installed a heat pump and electric furnace. I am amazed at how much more comfortable my house is, the fan is on low all the time so the air is constantly circulating and it keeps the whole house at a constant temperature where as before some rooms were colder than others. You never even hear the fan, the only way you can tell it's working is I have a plant near one of the registers and I can see slight movement in the leaves. Apparently this fan uses less power than a ceiling fan to operate and even though we have had a few nights down to around the freezing point the furnace hasn't kicked in. I do still have a small propane fireplace in my Florida room that will keep this place comfortable in case of a power outage but in the 8 years I have lived here the longest I have been without power was 36 hours during last winters ice storm. Little things like the sun shining in my living room windows in the afternoon, instead of just the living room getting hot, that heat gets distributed throughout the whole house. Cooking dinner last night, instead of the kitchen getting hot, it distributed that heat, keeping the kitchen comfortable and the rest of the house actually rose above the temperature set at the thermostat. Time will tell but so far so good!
