Well I officially wimped out this afternoon. I turned on the furnace here on Flannery Bay. It will now be gulping along until April, sucking up that very pricey LP. This is just about as late as I can remember for kicking on the heat. The past two weeks of warm, sunny weather have provided sufficient solar gain to make the house tolerable. But two days of 40*, rain and cloud cover have made it too cold to handle.
I have hot water in floor heating. You don't just flip a switch and get hot air blowing around in a few minutes. The entire granite covered concrete mass on the first floor has to be warmed to get heat moving into the house. This is not the kind of system that you can twist the thermostat a few degrees because you feel a chill. Of course late this afternoon the tile floor in the master bath was a toasty radiator to my stocking shod feet.
I am going to have an interruptable electric heating system installed soon. The current LP system will then become backup if the cheap electric service is strained and cut off. I don't anticipate that happening too often, given that the service has only been interrupted 5 times in the past 4 years and then the longest period was 4 hours. Then that large heated thermal mass will keep me warm until the electric is restored.
