Title: Burning coal without a shaker grate?
Post by: walkerdogman85 on February 13, 2015, 06:42:25 PM: I have a hardy H-4 without shaker grate, I am wanting to burn lump coal. I found it for 70 dollars a ton. Will it be ok to burn coal only? Possibly burn some wood with it too just not as much..

Post by: walkerdogman85 on February 13, 2015, 11:53:05 PM: Ok. I'm going to try it maybe even this winter yet? I have done some test buckets in it and have been impressed with burn times and recovery!

Title: Re: Burning coal without a shaker grate?
Post by: walkerdogman85 on February 14, 2015, 05:42:05 PM: I'll post the number later when I get to work. That's where the add is.

Post by: AirForcePOL on February 14, 2015, 05:43:41 PM: You will probably have a hard time burning coal in a natural draft furnace. It needs a lot of air to burn.

I am in watertown and have been getting coal in new lexington. It is also $70 a ton. They will allow you to hand pick it from a pile or they will load you. The stuff is straight out of the mine and unprocessed so the large pieces are larger than a beach ball.

Its the tunnel hill road reclamation mine.

Title: Re: Burning coal without a shaker grate?
Post by: walkerdogman85 on February 17, 2015, 03:45:10 AM: I got some coal yesterday for free. I'm headed out now to check it.
Title: Re: Burning coal without a shaker grate?
Post by: DaveWertz on February 17, 2015, 09:24:04 PM: No it will not hurt it not using fire brick.

Post by: wissel12 on February 18, 2015, 06:24:32 PM: I went to my local feed mill today and bought some coal. I got 180 lbs to try out. It seems to be burning good. I put really dry oak down first and then the coal. It sells for 180 a ton. I took a picture, but the up loader is full. I'll try later.
Title: Re: Burning coal without a shaker grate?
Post by: walkerdogman85 on February 18, 2015, 08:39:58 PM: I am impressed with coal. I gave some to a friend of mine who also has a hardy and just after one night he wants to go buy some bigger stuff. It has cut my wood usage more than 50% in the last 3 days at temps 0 and below at night! My job is based off of coal so I'm going to heat off coal....
Title: Re: Burning coal without a shaker grate?
Post by: wissel12 on February 18, 2015, 09:06:56 PM: I'm with your friend. I'm going to buy half a ton on Friday. I think with the natural draft, It will only burn when real cold out side. I set my differential to 4. I tighten it up to keep the coal hot.
Title: Re: Burning coal without a shaker grate?
Post by: walkerdogman85 on February 19, 2015, 03:44:53 AM: I'm not sure how to set my differential or I would do it. Coal does need alot of air.
Title: Re: Burning coal without a shaker grate?
Post by: wissel12 on February 19, 2015, 05:21:01 AM: Here is a link for honeywell aquastat. http://s3.supplyhouse.com/manuals/1350890933994/83991_PROD_FILE.pdf (http://s3.supplyhouse.com/manuals/1350890933994/83991_PROD_FILE.pdf)

When you take the cover off the aquastat. You will see a white dial. That is your differential. It should go between 5 and 25. It is on page 9 shows the white wheel. The big wheel in the front is your setting for your high limit.

I hope this helps.

Post by: walkerdogman85 on February 19, 2015, 06:06:27 AM: Thanks, I saw the high point setting as i turned it i realized thats what it was as the fan was coming on and off as I adjusted it. Ill study the the link you sent me and set it closer. Thanks alot for the info
Title: Re: Burning coal without a shaker grate?
Post by: AirForcePOL on February 19, 2015, 10:09:59 AM: I would recommend just buying a Ranco aquastat and replacing your Honeywell.
Title: Re: Burning coal without a shaker grate?
Post by: MD20/20 on February 19, 2015, 10:45:37 AM: I like my Ranco a lot better than the old Honeywell aqua-stat- I can easily read the settings.
Title: Re: Burning coal without a shaker grate?
Post by: walkerdogman85 on February 19, 2015, 11:37:04 AM: I have heard that before about the Ranco, what makes it better than the Honeywell? I haven't had any issues with it in the 3 years I have had it.
Title: Re: Burning coal without a shaker grate?
Post by: walkerdogman85 on February 19, 2015, 11:50:48 AM: What would you guys set the differential at?
Title: Re: Burning coal without a shaker grate?
Post by: Vincent Paul on February 19, 2015, 03:38:17 PM: hey wissel12, we also have a Ridgewood 7500, let me know how the coal works out. I have a coal mine 7 miles from our farm which sells lump coal for $80/ton..................Vincent Paul
Title: Re: Burning coal without a shaker grate?
Post by: MD20/20 on February 19, 2015, 04:17:06 PM: I like the digital display. It allows me to set it exactly where I want it (which is not always where it should be!).
Title: Re: Burning coal without a shaker grate?
Post by: walkerdogman85 on February 19, 2015, 06:15:51 PM: I looked at the aquastat and there was no differential wheel in the back. Looks like I'll be buying a different one for next winter, although since burning coal on these below 0 days the hardy is running often..
Title: Re: Burning coal without a shaker grate?
Post by: AirForcePOL on February 19, 2015, 06:26:19 PM: Yea there's a few different models that Honeywell sells. The one I had on my hardy was not adjustable and permanently set to a 10 deg differential. Get on ebay, they sell ranco controllers for $43
Title: Re: Burning coal without a shaker grate?
Post by: walkerdogman85 on February 20, 2015, 03:21:43 AM: Ok. why did you get rid of your hardy? I have considered selling mine and getting something else..
