    en.wikipedia.org/wiki/Trace_heating

    If a line becomes frozen because the heating was switched off then this may take some time to thaw out using trace heating. This thawing out is done on the three phase systems by using an 'auto transformer' to give a higher voltage, and consequently higher current, and make the trace heating elements a bit hotter.

    Because certain combinations of check valve failure and/or system backpressure cause the relief valve to discharge, the device must be mounted in a location where the drain will not become flooded. An example of where backflow would harm the water supply is the use of well washing devices inside underground sewerage pumping stations.

  7. Frost line - Wikipedia

    en.wikipedia.org/wiki/Frost_line

    The frost line—also known as frost depth or freezing depth—is most commonly the depth to which the groundwater in soil is expected to freeze. The frost depth depends on the climatic conditions of an area, the heat transfer properties of the soil and adjacent materials, and on nearby heat sources.
