This was my thinking originally...if warm water is
good, then boiling water will be
better. However, an AC repairman cautioned me on that. He said the glue on PVC pipes is meant to distribute domestic
hot water which may be about 140-150 degrees, depending on how high you set your water heater. But the glue is not rated for 200 degrees and too many cycles of 200 degree water will cause the glue to fail. Then, you've got a leaking connection beneath your slab.
