Personally, I'd concentrate on keeping the UGF fed with oxygen as a
priority
over the heating (unless you live in a very cold place). Oxygen starvation
in the gravel will quickly kill the bacteria in the filter. The last time
I
lost power for a few hours, the temperature only dropped a few degrees but
I
still lost a couple of fish a few days later.

Thanks Mark the Powerheads on the UGF don't draw much current, so they I
have them on there now. The temp does get down to the low 50s during the
winter months, hence the concern about the heaters. I guess the tank should
hold it's temp for a while though, even at 50°F.
