Just north of Philly, power was out for 11 hours yesterday and I consider my self lucky to get it back. House temp went from 71 to 60 before I got the boiler back on line, and then it took a good 6 hours to get it back up to temp.
Indirect kept the hot water hot for 11 hours, as soon as we had electric back all six of us were able to take showers. Boilermate for the win!
Yard looks like I was on Obama's drone strike list, however. I had 4 40foot white pines, and a good 1k lbs of branches have flattened all the landscaping that was underneath them.
