Brrr

This is our thermometer.  The top left number is the temperature outside in Fahrenheit.  The following two gauge the temperature of the bays underneath the living space.  The latter one is more important because it reads the environs where the water supply comes in.  It should never be near freezing.  As you can see, we're doing good in that bay.  So good in fact that it's warmer there than inside which is read by the last number. 

It is coooold.
