On the 22^nd of October, the Andy Shack was converted to heating mode by draining the water from the roof panels and activating a solar powered pump to circulate the water through the roof during periods of sun. It took about two days for the Andy Shack to reach its operating range once heating began. Since the Dave House North has a much larger time constant than the Andy Shack, it will probably take several additional days for the Dave House North to reach its steady state temperatures once its heating system is completed. Unfortunately, the probe monitoring the Dave House North malfunctioned and no data was collected on it.
