The description really doesn't do service to the actual issue. I woke up to a freezing cold home (50 Degrees according to the thermostat). So we shivered and ran around the house trying to figure out why the furnace wasn't working. It took us a half hour to figure out that the digital thermostat needed new batteries, but we got it sorted out before any further catastrophe could occur.
This reminded me of the ice storm that effected parts of Ontario and Quebec a few years ago. During this period we had no power for several days and damage from burst water pipes was common place. A constant vigil was required to keep the pipes from freezeing. Hopefully that will never happen again to anyone.
It also got me to thinking about all those people that are avoiding the freezing weather by heading to warmer locals. There houses are often left unattended for days. If this had happened while I was away we could have come home to a huge mess as well. It is a good practice to have friend or relative to look in on your home while you are away.
