I purchased a DS Stoves Kozy King 300 furnace that ties into my central air ducts last March. Last year I only burned coal for approximately 3 weeks before switching to wood that I already had split in the yard. This year I plan to burn coal most of the winter, but am concerned at how quickly I went through it last year. For the short time I was using coal last year, I was burning approximately 100lbs a day. If I put in a 50lb bag, it would burn in approximately 12 hours. When I put in 100lbs, I just seemed to have a larger fire, but would not get a significantly longer burn time. I have a 2100 sf house that was being heated to as high as 88 degrees while it was 20 degrees outside. My goal is to reduce the amount of coal I burn and keep the house temperature closer to 75-80 degrees. Is it possible to reduce the size of the firebox by lining the perimeter of the grate with fire bricks so that I still have a deep bed? Is this the best way to go about it? I imagine the bricks would fall when shaking the furnace. I am looking for a way to dial down this massive furnace that may be overkill for my house to conserve my coal and keep my house at a reasonable temperature.
Thanks for your help.
p.s. I had the draft blower off and the spinners on the ash door and loading door barely open.
you got a bit of an eye opener. huge stoves with big fireboxes, you will be amazed at how economical they are not. at 100 lb./day that would be 1.5 tons a month, or around 6 tons a year if burned Nov-Feb 4 months. add another 1/2 ton for shoulder months heat. at the current price of 200/ton at the source, that would be 300/month for coal heat. there are many heating their homes with city nat gas and hot water too, for less or equal that. see what happens ? you can easily put in alternative heat that costs you more than standard heat and it becomes a lose-lose deal, because the stove also has to be lit, fed, raked, ashes taken out.
reduce average indoor temp to 70-72 degrees. the best way to heat is, put a stove in the actual living quarters such as LR or kitchen, the floor the stove is on is always the hottest. if you reduce the size of the firepot, you will also reduce the heat and temp level in the house as well.
perhaps the fire just needs some judicious tending and dampening ?
