Hello. We recently purchased a cabin built sometime in the 1940s, which has radiant electric ceiling heat. It is located in the Midwest, where winter temps can fall below 0 deg F. To our knowledge, the previous owners did leave the heat on over the winter. I vaguely remember hearing that leaving the home unheated can cause expansion/contraction and damage to the plaster, but cannot find a source for this or a similar message board toipc anywhere. The heat is very inefficient (old windows and poor insulation?) and expensive. Please advise if we will be causing severe damage by fully winterizing the pipes and leaving the heat off through the winter? Thank you!
