Unbelievable!  Yesterday the temperature was minus 4 degrees when I got up!  I thought we were having a heat wave by noontime, it was ten above!  Stayed that way all day!  Today I got up and it was just zero outside!  Although I had the heat cranked up to about 78 degrees in the house, it felt like 60!  I could just feel that oil running right through the furnace!  Oh well….  a little overtime will pay for it!
