The water in the well at the farm-house was freezing up because the light the runs at the top of the well, which keeps everything warm, had burned out. We changed the light and about an hour later there was water again at the house. I find it amazing how that works: just a regular light-bulb is in a vertical, circular, metal, culvert that is about 4 feet wide and it is about 5 feet deep to where the open water sits. From there the pumps move the very cold water. It is a lot of space for air and there is a lot of cold water to keep cooling the air that the bulb heats in the space. The well is covered with a tarp at the top and somehow that simple light-bulb keeps things warm enough inside that nothing freezes, even though all of that water is so cold. That simple light-bulb is able to thaw water that has froze in the well, in only about an hour of time. Incredible.
