A couple of things to add to the circulating cold weather tips (from our experiences)- double check that your CO alarm is working. They are important in daily life but extra important if you are supplementing heat inside.

Know that your normal heating system MAY NOT KEEP UP with what you have your thermostat set to during extreme cold weather and may burn through more fuel than typical.

That means you should also be sure your fuel level is high enough to make it through.

Just because you have never had frozen pipes before does not mean they will not freeze this weekend. There are too many changing variables to guarantee that.
