Quick update. Its now 2220 Spongebob Squarepants is on (no idea why its on this channel). The new DS-1600 is idling at 520* as of this posting. Stack temp is 210*, MPD is closed 3/4, baro is seeing .05"wc.

House is 76*. It's 24* outside (weather says no wind, but I just went into the basement to figure out why I have no hot water [stupid fuse in the disconnect switch is blown] and there was definitely a very strong wind walking from the deck to the basement).

Low for tonight? 11*. Stove is stocked with coal. I (rather my wife) shook down at 2000 and filled the hopper. I just did another quick shake down at 2200 and put another 5 pounds in.

I'm going to bed.

I'll give another report tomorrow.

Great news !...I am glad to hear you are finally warm and not having to burn at MAX like ya were.
Sounds like ya have your new unit just cruising so you still have plenty to go if it gest super cold.
Congrats!

ThanksTim!!! I'm glad I finally have a stove that will keep my house warm.

I feel like I'm using about 50 - 70#'s of coal a day with this stove running around the same temps I did on the Chubby. I was using around 80 - 100#'s of coal with the Chubby.

It is now 0630. I shook down at 0600 stove was idling at 530* when I woke up. House was 73*. I shook down added about 10 pounds of coal and just for fun I tossed in 4 small shovel fulls of coal through the front door, I didn't need to but wanted to). Low for last night was 11* woke up to 22*.

Stove is currently at 470* and the house is 72* (after I knocked some heat out of the stove with the fresh charge).

Just a comparison.

Chubby running at 500* with a low of 11* house would be 66* and the furnace would have been on twice; once early am (00)then again at 5am.

Chubby running at 530* with same low would have been 68* and the furnace would have been on once.

Chubby at 600* house would be at 69* with a high of 30*.

As I type this I can hear a slight breeze outside.

Fire: I am glad you are happy with your installation and everything sounds good. You know as well as I do, however, the above numbers do not make sense. Where was the heat from the coal burned in the Chubby going? Up the chimney? Those BTUs went somewhere!

11' cieling in the living room. 10' cieling in the dining room. 16' ceiling in my son's room (measured from the living room floor to his ceiling; its a loft.)

That's where the heat was going with the Chubby. It couldn't keep up.

Chubby is rated for exactly 48% of what the 1600 is. That leaves me with an additional 65k BTU to play with.

I believe what you are saying and that you perhaps have a hard place to heat, however, being a Chubby lover I am trying to understand the DS machine comparison. 100 lbs of coal a day is 50k BTU/hour. This is an ENORMOUS amount of energy. BTW the Chubby is rated for 70k BTU/hour so you were not over firing it, so it seems. My gas usage which I know exactly was 40k BTU/hour in the coldest winter months, heating 3 floors. Now I leave the basement unheated, keep the main floor toasty and let the upstairs be cooler. This I can do with 40 lbs of coal per day or 20k BTU per hour. If I pushed the Chubby harder (double the coal burn rate is roughly 40% higher stove temperature) and could circulate the air, I could heat the whole house to the same temperature as with gas. You could also make a oil/coal comparison from your past heating bills. The DS machine can only keep your house warmer than the Chubby by burning more coal per hour. The Chubby is a very efficient stove (the DS machine too, presumably).

Wouldn't the surface area the stove has available to radiate heat also come into play wrt its ability to heat the space.

The DS Machine has double the heat exchange surface of the chubby. For equal stack temperatures it will always put out more heat than the Chubby. The DS stove is also hopper fed and will probably burn a higher percentage of volatiles. At higher firing rates the DS stove will have much lower stack temperatures.

It is totally agreed that the DS machine is a more powerful heater than the Chubby. No comparison, no argument. My point is the higher heat output can only come from burning more coal per hour.

On initial startup I had 120#s of coal in the DS. At 2300 that night I shook down to get the Cowboy Coal ash out and only needed to put in a 1/4 coal hod. The following morning (Sunday) after running the stove on the low side 400* I shook down again and put in only another 1/4 hod (mainly because there was more Cowboy ash that needed to be cleared). Last night after running the stove 500* - 570* all day (give or take a few degrees) I shook down again and only needed a half hod. This morning I shook down put in a half hod into the hopper and then I threw 5-6 58oz grain shovel fulls into the fire box through the loading door.

Yes, there is always 120# in the DS but it hasn't been burning 120# every day and night the past two days I've burned I've noticed that there is still something left over in the hopper that doesn't get burned in the time between filling and refilling.

In regards to the Chubby, I did like it. It worked well on warmer days. Just didn't work so good for me on the colder ones. Your results are different than mine and I just didn't feel that as the weather grew colder the Chubby could do what I wanted. It would have been nice if it could have, then I didn't have to hear my wife complain that I spent almost $2K on a new stove. As far as the Chubbys' BTU rating, I'm not sure where the 70k rating came from. I've seen old sales flyers (there was one posted here not too long ago) that stated it was rated at 60k. I'm only basing it's numbers off of what I've seen it being rated at. Who knows, perhaps the JR is rated at 60k and the SR (one I had) was rated at 70k. But I've only ever seen 60k in writing. Even if the SR is rated at 70k it's still 56% if what the DS is rated and it still leaves me with 55k extra BTU.

I'm not putting the Chubby down. I loved the Chubby. I wish I had room to of kept it and used it after the DS was installed. It just wasn't big enough for me. I'm a cold blooded person, if the lower temps in the house produced by the Chubby could of kept me warm I would've kept it. But I like my house hot.

Hi, could you please give the exact amount of anthracite you need (pounds) for 24Hrs period , at a certain outside T*? I don't know the quantity of the hood and of the grain shovel you talked about.
Thanks

As the heat output goes up the DS Machine stove will do it more efficiently. Even at a rate of 40 pounds per day it will put out more heat than the Chubby because of its greater heat exchange surface and hopper feed. You are assuming equal efficiency which the smaller stove just can't do except at very low firing rates. To reach 60 or 70k BTU output the Chubby would have to burn well over 100 pounds per day. The sides would be glowing red and the stack temperatures would be out of sight.

Fire: I agree with what you say. The Chubby certainly has it limits. Perhaps when you pushed it, it became inefficient. I discovered it has a sweet spot for my installation, with the MPD closed and the air door open 1/8 inch, resulting in a nice steady 12 hour burn on 20 lbs of coal with 1/2 fire pot left so no danger of going out. This for me raises the temperature of my main floor by 40 degrees over the outside. When it is 30 out, a typical Cape Cod winter temperature, it is perfect for me. When it is colder, I choose not to fire the stove hotter (but I could), but instead I light a wood fire in a second fireplace. The fireplace has an insert with a blower that claims to be 40k BTU/hour, probably some fake number but it throws out all the extra heat I might want on a cold night. Who knows what the chubby is 50-60k-70k BTU/hour, does not really matter as normally the stove is not run at this level, although Larry told me of a guy once that ran his at 900 with no issues except he needed an occasional grate replacement! It seems clear that you need/want far more than 40lbs of coal heat per day and the DS Machine can deliver if you feed it!

Respectfully disagree, the Chubby will run at the 40lbs per day rate at 90% efficiency and NO stove will beat that. At higher burn rates, I agree with you and the reason has nothing to do with the hopper but rather the increased convective cooling due to the large size. The Chubby blower with its forced convection will do even better for higher burn rates.
