Coalfire wrote:[quote="wsherrick"]I don't know how your house is set up. In the coldest sub zero weather I never burn more than 40 or 50 pounds of coal a day in the Glenwood. Others may have different results. I am reporting the results I have obtained with it and compared it to all the other stoves I have ever had or been around in a half century of heating this way. I don't know how much surface area your DS has, but; the Glenwood has over 27 square feet of radiating surface area to work with.
My stove has 30 square feet of radiating surface. So what do we do now? It takes X amount of btu to heat an area if the heat doesn't go up the chimney it is going in the house. You can't get around that it is a simple fact. So I doubt there is anyway a glennwood would be more efficient. but here is the flip side maybe the DS would be more efficient for you
Nice try but no cigar. What is this X Btu in the house or up the chimney stuff.
You need to explain that to me so that I can understand what you are saying. How much coal does your stove burn over a set time to produce how much heat, what is your stack temp, what is the stove temp and the difference between the two??? How efficient is your stove at not only radiating the heat produced, but; how efficient is the combustion the fuel in the stove? How much potential heat is lost in unburned gasses going up the chimney? All of these questions are relevant to how efficient any heat producing device is. How much work is obtained out of the total potential energy available? If your stove has 30 square feet of radiant area that's a pretty big box you got there. The amount of BTU's to heat any given area depends on condition of the area. Heat loss, air infiltration and other factors depend on how many BTU's to heat an area. There's also some one's comfort level. That is also dependant on how warm some one likes an area to be. Can your stove heat a two story house and basement and burn 50 pounds of coal a day in sub zero weather to do it? If your stove can do that fine, but; I bet it can't. I seems like you are taking this quite personally and you don't need to. Maybe you should trade the box for what's behind curtain number 3.[/quote]
Nothing personal and I'm not going to try and argue it cause your mind is made up and that is how it is. I don't understand this two story house and basement stuff, see you will have to explain that to me size and temp that your are trying to achieve with your 50lbs of coal. Like someone said are you heating a 4000sqft corn crib or a 1500sqft house? You said 50lbs of coal 50x13000= 650,000btu per day if you get every last ounce out of the coal 650000/24= 27,083btu/hr average. so your are saying I could put a 30K btu space heater in the basement of a two story house and heat it comfortably on a sub zero day?
Oh by the way what is behind curtain number 3? I hope it is one of those electric amish mirical heaters, I heard that whole amish communities were working there fingers to the bone so every household could have 2. They run for pennies a day you know, someone on the infomercial said there furnace went out and they pulled out there mirical heater and it saved the day
