Slinky Coils
A cousin of the horizontal loop system that is useful with new constructions in soil
or clay based land, and in areas that don't experience extreme weather. They
are called Slinky Coils, because the piping is laid out in the six foot trenches in
large overlapping loops. A backhoe or trencher does the work, and 400 to 600
feet of loop are laid for each ton of heating or cooling. Depending on climate, the
heat pump's run fraction, soil, the system is between a third, and two-thirds
shorter than a traditional horizontal system.
