If I follow correctly, according to the OP, water is needed for animals. That makes turning the water off / draining / winterizing the pipes very impractical if there are animals to water and he is going in on a sled. Looks like heat on with remote monitoring is really the only reasonable solution??????
Depends, would be very easy to install a valve allowing a hose bib in basement to be used while blocking water to the rest of the home.
