Those reptile heating pads had the same idea.

Nothing novel certainly, folks have been doing it for many years.

Heating cables are not bad for heat distribution, which was the main reason I felt they were useful way back when, prior to using them for planted tanks.

You can search my comments off the APD from year's past.
I have done my part to save folk's $ and see the cable go the way of the dodo. They are not bad per se, but they do not work according to the maker's claims, and they cannot support these claims other than with "the tank's long term stability is improved" beliefs.
If the effect is that subtle, is it really an effect?
How can you suggest it is significant without a control?
Is the control really a control?

More often it is not.

I'd never suggest anyone to use one.
Yes, I've used them for 10 years, had 7 of the god forksaken things.
