UGF with Heaters

I liked the idea--the simplicity--of the system Karen Randall described on
the Krib, and so decided to imp lament it; unfortunately I scoured the
_country_ and could not find the Schego 7.5W mini heaters anywhere!
(Everyone told me they had a very difficult getting them for several
months) What I ended up doing was using 25W mini heaters, one on either
side of a 30"X12" tank. To prevent any heat damage to the uplift tubes, I
replaced the thin plastic 1" tubes with much thicker (but clear) 1" PVC
tubes I bought at my aquarium supplier...I set the heater, after much
fussing with a silly control system, at around 78F.
Because I live in Southern California where it is warm A LOT, I wasn't
concerned with providing great amounts of heat year round, and routinely
keep my house at about 70F-78F. What I have found is that the heaters are
on a lot, and will anticipate replacing them every year at least, as I
think these poor little 25W'ers struggling to heat 30 gallons will wear
them out rather quickly. The water temperature has been pretty constant at
76F.
Also I have 3-4" of gravel in this tank, and so thought the extra wattage
might help the "pull" through the substrate, but not at any dramatic rate
such as with regular UGF's... I have been measuring the temperature in both
the tank, and 2.5 inches under the substrate, and the temperatures have
been identical.
The system is only a few weeks old, and so cannot comment on if it "works",
though I have to come to value Ms. Randall's opinions and advice greatly,
and if I remember right the idea was developed by Claus Christensen of
Tropica, and if you can't trust Mr. Christensen and Tropica, who can you
trust!?
Best,
