Bob,
I have this type of UGF system currently in operation,I had
used the pvc pipe idea from a magazine article titled hot gravel.
However instead of using a power head,I took a old impeller
pump off a broken WHISPER outside filter,and glued in on
the outside the heating container using silicone glue.
Oddly enough I checked the temperature over the whole surface
of the substrate,it was fairly consist temperature.Worth trying.
