We have had one of the coldest winters ever here. December 2010 was the coldest Dec on record. I think we have had our heat on more this winter than in all the other years combined. WOW!
Today in Naples the weather is:
Wind: NE at 11 mph
The first time each year that we turn the heat on (if we have to), we have to make sure it is not in the middle of the night. Every time the heater kicks on for the first time of the year the smoke alarms go off. The dust that has accumulated on the coils burns itself off (or so I've been told) and the although there is no 'fire' the smoke alarms go off.
