Hey there. Name is Blair. I'm not new to burning, but seeking advise on what I can and can't do. I've had free standing wood and coal burners, and now am in a home with my first fire place. We bought the house last year, the fireplace is in a basement family room. I cleaned it from top and bottom openings best I could using extendstion rods and a round chiney brush. We burned ALOT of wood last year trying to supplement the heat pump. Now the questions.... After having used the fireplace, I need more heat. I have been looking at inserts, coal and wood. My fireplace is not masonry. It's a Superior brand, metal with the fake firebrick, the flue is metal, I believe the double walled type through a chase on the main floor to the roof. I have been told I can't pull the fireplace out and stuff a insert in with that type of flue pipe, (metal, no masonry), and not having a masonry fireplace itself to use as a heatsoak if I'm using the right terms. So am I on the right track? My fireplace cannont be made into a insert? Could I get a free standing stove and using the appropiate distances to combustables in the basement still use my metal chimney? This was how we burned our coal in the last house. Douoble walled chimnet stack through a ceiling support box and out the roof. Straight and simple. All my stove's have been Harmon's, I'd love to get one if I can't do a insert due to lack of masonry in my situation. Thanks for any thoughts or advise, wish I had found this forum last year, or a few years before that when I first started burning coal. Blair in Virginia.
