........give me an estimate on running a dedicated circuit for the "Hillbilly" installed fireplace. Was told there was no room in the breaker box for another circuit. Huh?.......
I doubt your panel is full.
Sorry for the poor picture. If you can see it, my panel now has no open breaker slots, as I recently added two, double-pole breakers (four 15A circuits) on the far right (not yet labeled). If you have available locations, there will be a plastic knock-out in place of one or more double-pole breaker modules. (You can also see one of the new outlets I've added right next to the steps and vacuum cleaner hose connection.)
In our BH circuit panel, there were two open breaker locations from the factory that both fit double-pole breakers, for a total of four spare circuits capacity available. You'll have to look to verify if open spaces are available in your panel.
I recently installed two double 15 amp breakers (Cutler-Hammer type BRD breakers, about $8 each), and wired 3 new dedicated 15 amp circuits with one outlet on each. I installed one outlet in the bedroom, one in the wall adjacent to the breaker panel, and one in the living room. These breakers are available with one 20 amp and one 15 amp breaker in the module as well, for a few dollars more. I didn't feel that I needed 20 amp circuits, so opted to save a few dollars. I did run #12 wire so that the wiring is capable of 20 amps if was to up-size the breakers later. I have one 15 amp breaker unused remaining in the panel at this point.
I also was able to do a little playing and make sure the circuits I added were on the least loaded hot-leg to minimize the likelihood of tripping the main breakers under "normal" use.
The hard part was running the wire and cutting in the outlets. Doing it myself, all three took about 10 hours.
A 1500 watt load (like most space heaters and the Dimplex fireplace) draws 12.5 amps ( watts / volts = amps ).
Hope this helps.
