Cold breaking records throughout the US!!!!

living in Va with temperatures normally in the 20's or teens at a normal winter night.  This morning was -5 and wind chill around -28 below..... brrrr cold very cold..... but my yurt was 68 this morning and after I stoked the fire it went up to 75 with 0 outside.  I am very happy with the results of my heating in our yurt.  no pipes freezing due to my barrel of water inside the yurt... so I have water where my neighbors may not.
