Just ordered a Harman Mark III. It won't be in until the end of March so I'm really planning on it for next season. Any of you out there with this make and model have any words of wisdom for me. Such as which size coal works best? I'll be ordering my coal for next season and want to make sure I get the best possible size.

Either Nut or Pea. Depends on your preference. The nut will produce more more heat at the moment and burn easier....but faster. The pea is more contolaable which if your in a very windy area might be better.

I have one customer who purchased range which is a nut pea mixture for the beggining of the season because he could cotrol it better and just nut at the beggining of December so he could fire it up more. You can probably achieve the same amount of heat output with both but it will take you longer with the pea.

I always suggest to customer that are new to burning coal to get a few bags and try each out and see what they prefer

I used a MarkIII for 3 years and currently I am using the SF-250. Both units have the same grate sizes and configuration.. I am referring to the space between and type of grate. Obviously the fireboxes are not identical in size.

The last load of coal I bought locally is listed as nut but I would consider it range as there are many small pea size chips mixed in. I do not like it. I have a very difficult time shaking down the ash. I lose too much unburnt coal and small hot coals as it falls between the grates. It has been quite frustrating this past 2 weeks. I refused to purchase from this dealer twice so far this season for this reason but gave in last w/e. After today, I have decided I will not go back to the same guy. I know of a dealer with true chestnut size coal just a little further away.

What I do not understand ( maybe coalman can answer ), both dealers buy from the same source in Hazelton. Coalman, I am sure you know of the source.

Hi Tom, I bought a Harman Mark III last November. This is my first year burning coal and I am more than happy with my stove. I had problems getting it to burn slow on the warm days we had this year. I was burning nut coal in it and when I would turn the draft down so it wasn't so hot in the house the fire wanted to go out.

I posted a message here and the Coal Man told me to try burning pea coal. It was time to get more coal (Don't have a bin yet and only get 1/2 ton at a time) so I got pea coal and have been using it since. I can burn the stove real slow with pea coal and the fire won't go out. I am sure you will be happy with your stove. Hang out here and you will learn alot. Great bunch of guys here.

Thanks for the replys. This is not my first time burning coal it will just be my first time burning with the Harman Mark III. I once had a Rite way model 37 for years. Recently I started burning again with stove that was given to me this season. It is a Surdiac Gothic. It is small and I've pretty much burnt it up trying to heat my whole house with it. I burnt nut and pea in it this winter. Pap, have you tried burning a mixture of the nut and pea coal together in yours?

Actually I'm not familiar with any of the business's down that way. There's always going to be some amount of pea in the nut. Consistency in sizing varies by breaker, where I'm getting it the uniformity borders on the ridiculous. That's one of the comments I get from new customers.

No I haven't tried that yet. The Coalman said that mixture is called Range coal. I have thought about mixing some to try but haven't done it yet.

Dealers down this way go north toward Hazelton to buy inventory. I'm told Jetto

Well I'm familair with Jeddo, not any particular dealers though. It's my understanding they have a outstanding product. Not feasible for me as that would entail a extra 2 - 3 hours per trip which is unrealistic no matter what the quality is.

Tom,

I received my Mark III the end of Dec/05 and have been using Nut in it since ,, but I believe it is more Range with a mix of Nut/Pea. I also have found it some what difficult to shake down. I bought a few bags of Stove and used it with the Nut and the stove ran better and was easier to shake down. My draft is a little weak because the chimney is too short at 14 feet. The new house I am building will have a 30+ foot center chimney.
