Need some pics. Not quite following what you have going there.
For the initial extraction, I just put the cappings into a pot of water and brought it all to a boil. Once cooled I picked out the wax disk that was floating on top of the water(and other stuff), melted it in the microwave and strained the dirty liquid wax through a nylon stocking. Came out rather well in the end.

My bucket was a 20 Lit./5 Gal. metal paint bucket that was cleaned out.
I punched a hole and mounted a element from an electric kettle, about 4 inches from the bottom.
The Kettle had a cord that fit the element.
And I used a slab of blue styrofoam insulation to cover it and keep some heat in while brining the whole lot to a boil.
Pretty much the same as you were doing, on a larger scale, in the garage instead of risking the wrath if the kitchen took a wax spill.

I made, essentially, a giant sized electric kettle.
The solar melter was a double glazed commercial fridge door that came from the local dump. I built a plywood box, stuck some random scraps of insulation into the bottom, and vee'd a sheet of counter top material (formica?) by heating along the bend with a torch.
It was sat on some blocks, high enough to drip out the one end, into a old bathtub half full of water. The hot wax that ran out the drain hole, cooled and floated, the honey that was crystallized in the comb went into the water.
With those rigs, I processed near to 100 full height boxes of frames, from some really bad winter-kill we had the winter before. Most of it was full of crystallized Canola honey, which the remaining hives in my yard could not have cleared out in any reasonable time.
That clearer?
