We had a good stretch of cold culminating in a few days of near record cold. I was burning wide open through the end of it and still am 2 days later in the low 20s. While the air temp in the house never went below the low 70s, the space behind the counters and the unheated basement froze and still isn't thawed out let alone warm. In fact, I had to use a portable heater to thaw out the lines to and from the dishwasher as it didn't seem like it was going to happen on its own. For those of you without backup heat, how long does it take you to recover?
