I have a 110v system running off an
inverter from my house bank.
It draws about 14 amps when running - way too much and it has no thermostat control - has to be switched on and off as required. It's a PITA
I'm about to replace it with two smaller units - both 12v and the spec says average current .55 amps - max 6.0 amps. Hopefully these will only run one at a time and then at a much lower current draw.
