Realize that black rod in a coil or encased in black corrigated drain tube as a 
shipping container and exposed to sunlight will get very hot, even if the 
ambient temperature is not high.

In a coil, there is no or uneven air circulation as well.

This probably contributed to our coiled failures.  Even tho it was received 
during the Winter, much of it layed around til at least early Spring as I 
recall.  However, I know I had failures of a coil that was laying in shade (in 
a run-in shed) most of the time.

So, yes, if you decide to leave it coiled, store it in a shady place...even 
better a temperature controlled place...or paint the coil white...or order 
white rod!
