I've moved to electric heat as much as possible as it is cheaper at campgrounds where we do not pay separate for electrical use as well as far quieter.
To avoid the problem of the poor temp regulation of most electric heater thermostats, I have adapted a digital house thermostat to control the heat as it has two advantages. Advantage is that it tracks much closer, is portable and I can run it on the normal 1500 watts, using a stand alone 15 amp circuit. the high setting 1500 watt at 120 volts is 12.5 amp which gives me enough "slack" to feel okay. Lots of choices on what heater to pair it to.
The house thermostat is often thought of as being 24 volt but there are many which use batteries for the thermostat operation and they are then simply a switch where we can control the 110 AC for the heater.
Another, simpler option for the control is here:
I have not been able to get one at this point as supply is disrupted but I really like the ease of the idea. Value? Unknown!
