I installed a pair of genuine 15/20 amp outlets (These have a "T" shaped neutral slot) with 12ga wire connecting each to its very own circuit breaker.. No overheated wire any more.

Running those heaters on LOW or Medium (500-1000 watts) I would not expect problems.. Only on 1500 watt.

I need to buy a new one. One of my old ones bit the control board.

We are thinking along the same lines. I failed to mention that my special was for a dedicated (it own circuit breaker) non-inverted 20 amp circuit. My goal was to have adequate capacity for the heater at 20amp.

I installed two 20amp circuits IOT run space heaters. They are on separate phases and since I don't use my ACs when I'm using the space heaters I won't overload my 50 amp service. The upside is the rig is usually toasty without using propane. I also have some outlets in my wet bays where I use some 200 watt ceramic heaters so the wetbays stay above freeing too.

BTW in addition to the normal 120V circuit breakers in the RV electrical panel there are sometimes 1 or 2 120V breakers on, or near, the inverter/charger.

Or maybe not. I've run two 1500 watt electric heaters and a 100 watt bulb or 200 watt personal heater at the same time for over 15 years with no troubles.This is off a 30 amp circuit at the stick house over winters.

The present rig has an AquaHot with two 2000 watt elements as well was the diesel burner. There is no way I'm going to run both electric units off the 30 amps though. Will probably end up using one element and smaller heater along with the diesel burner over winter.
