Call them freezestats or low-temperature cut-outs or vapor-filled capillary tubes this week I am talking about the control devices that keep our water coils from freezing.  These little devices seem to cause a lot of issues so I thought that I would do a complete podcast episode regarding them.  I already have a blog post "A coils best friend" but some people, me included, perfer the audio format for our information.  So what are we going to cover in this episode?  We will talk about the pieces parts of the device, how it is SUPPOSED to be installed, and how the little thing operates.  I welcome any feedback on this one but I base this episdoe on quite a bit a experience and observations.
