This is what I use. Cheap dial dimmer, the nicer electrical box, an outlet and a switch plate.
What is not shown is the markup of the dial and switch plate, as this one is new and I'm trying a printout of the heater settings instead of drawing on the switch plate with a sharpie. Basically, I draw an arrow on the dimmer dial and mark the switch plate for full ON, 3/4, 1/2, etc down to OFF. Just makes it easier to know where your dimmer setting is.
Dimmer plugs into an ON/OFF controller. Easiest setup with lots of control. Poor man's proportional.
