There are tank pads made for 12V, 120V, and some combination 12/120v. Some have built in thermostats, some don't.

I have the 12V version installed (from the factory) on my tanks and drain pipes. They will drain a battery, very quickly. On the road, I use them sparingly, and shut them off during stops that may last more than an hour. On shore power, I can leave them on. Mine have the built in thermostat, that turns the heat on at 43 degrees and off at 44 degrees.

You can get both 12VDC and 120VAC tank pads.

The 12VDC heater than came with my trailer is only ~35W, so it sucks maybe 1.5A when on. Whether that's a problem or not depends on your charging system and batteries.

Of course, that's the raison d'etre of 12 vdc tank heating pads, for those times you don't have shore power available, but of course their effectiveness will be determined by the capacity of your 12 vdc system to supply power to those pads. For those who always do have shore power then 120 vac is the more logical choice.
