Terrarium Heating with Submersible Heaters

[SWAGnum]

I'm interested in setting up a terrarium for lowland Nepenthes, probably one of the larger exo-terra models. I already have an Intermediate/Highland grow-tent that does not receive supplemental heating. It averages daytime highs of 80 and nighttime lows of 60-65 without supplemental heating. I'm shooting for about 10f higher for lowlanders.

I have heard of submersible heaters being used to heat terrariums. Is this practical for larger terrariums/grow chambers?
