To me, Tygon is preferable to copper and one whale of a lot less
expensive. As for the heat transfer, It's not nearly as efficient as
copper, but as you have already seen, that can be made up for by just
using a longer tube. Tygon tubing is tough, flexible, and relatively
inexpensive. A great place for it is in the sump or weep tile where it's
quite a bit cooler than along the outside edge of the basement floor.
But most of the time I could use the heat in the basement any way.
