I then called one of my neighbors to check on the house. Within the hour he called me back to let me know that the house was flooded with water flowing out from under the doors.
An iron (from a thrift store) controlled by a thermal cube outlet (from a farm store). The plywood and tile sandwich on the face of the irn radiates the iron's heat. The iron set on "cotton" provided adequate heating and kept the pump and pipes from freezing. Needless to say, we rapidly became experienced winter campers.
After initiating a claim with State Farm, it was about ten days before we could get a flood remediation contractor (ServPro) to start work. ServPro and all the other contractors were swamped with frozen burst pipe jobs.
So now we are nearing another departure for our southward snowbird journey. This year we plan to linger the entire winter in central Florida with a fairly early mid-March return northward. Unless another disaster ensues, we are looking forward to a summertime trip across the northern states.
