More cold weather questions / Refrigerator Ice Maker

Update

So far all that I have done is working staying warm (somewhat) and no frozen pipes. Got to a low of 7 and is and will be below 32 for a few more days with a little snow.
One item I did underestimate was propane usage went through that faster than planned but on the way to Independence, the only place open on Sunday, to get Propane I got to see a Bald Eagle no big deal but it made the cold day just a little better.
