I have lived in many different places and for the last 2 winters I had to keep my thermostat at 58 degrees and 60 respectively.Budget contrains.... This winter I shall have heat to spare. A new woodstove with plenty of wood to burn. I expect to be clad in tee shirt and shorts as my sitting room is also the stove room. No matter how cold it gets, I shall be warm in my little house and oblivious to the outside climes. No power ...No matter. This is as good as it gets.
