Help With a Harman!

Modern and vintage hand fired coal stove are similar to a wood stove and in some cases can burn either. They need to be regulated and fed by hand usually every 12 to 24 hours depending on your usage. They require no power to operate making them ideal for rural settings with long power outages.

A co worker recently sold a Harman SF250 to another co worker for $100.00. Now that co worker is leaning towards an outside wood furnace and is considering selling it to me for my first new home for $300.00 which ill gladly play. Neither of us know much about stoves. The original owner said the grates are warped and need to be replaced. Can anyone help with how much this would cost or even if the parts would be available. Also what else should be looked into when buying a new stove. I don't want to buy something that will end up costing more than its worth in the long run. Thanks!

Hello and welcome. The SF250 is a very capable heater,, I'd buy it in a heartbeat. The grates are replaceable and available.. the stove costs in excess of $2000, so you have a good deal there. http://www.harmanstoves.com

If the grates are warped, it is usually caused by not keeping the ash pan emptied, which allows the ashes to build up deep enough that they touch and fill the grates. Without fresh air flowing from the ashpan area through the grates, they can overheat..

Using the shaker handle, move the grates back and forth if you can rock them about 1" each way without them jamming against each other, then they will probably work fine for coal.

New grates should be available from Harman. Call your local Harman dealer for a price and availability..

If the stove has been badly overheated, you may have some warped pieces, and this may be a problem or not. As long as the doors open and close, and everything fits, it should be OK.

The SF 250 has a built in heat exchanger, you need to remove the inspection cover and clean it out.

Hope this helps.. Greg L

I would try Harman for replacement grates. I recently ordered a new top baffle for my Elite insert from a Harman dealer. I got the plate from Harman for $60.00 had it welded in and now it is ready to go. Oh as far as why it burned through, I would say it was operator error, from overheating. I had new grates made for my stove from a local friend that works at a foundry.

Bargain central! :shock: :shock: :shock: :eek2:

If the grates cost $1000, you'd still be ahead of the game! 8-) Congrats on the great deal! :up:

As I was reading that the guy bought the stove for $100, I thought you were going to say the seller took it back........ because he realized he ROYALLY F**ED up the price!! :funny:

Just to give you guys an update I'm at work now and will be taking to the stove Saturday morning for $250 which is what the co worker figures he has in it with gas hauling it home, back and paint. From what he said the grates still function normally but are just a little wider from warpage than normal. Ill post some pics after I get it home this weekend.

Just a suggestion- if the stove was painted, you may want to fire it up once outside/ inside with many windows open to cure the paint and burn off dust & dirt, etc.

Heres an update and change guys. Need your help. The stove (which is in his truck now, were at work) is a SF-150 built 1981 not a 250. The two most rear grates are pretty warped. the other 3 don't look so bad. the gasket for the door is rough shape and I don't see a blower, was it an option. Im concerned that it to small. Anyone know the BTU of this stove. is $250 still a good deal? the living space I need to hear is 1175 but the stove will be in the unfished basement. how will I get the hear upstairs? ne help or advice!?

Grind the edges of the grates where they clear the saddle, about 1/4" minimum clearance should do it. They just need to swing freely with no binding. I have been running warped grates for about 10 years, just keep them freed up and they should work OK.
Nothing is impossible for people who don't have to do it themselves.

Yes, it is still a bargain. the SF150 is just 4" narrower than the SF250. There are several SF150 owner/operators on the forum.. they all like their Harmans.

If the grates are so warped that you think the shaking motion, or their ability to hold the coal is compromised, then order some grates from your local Harman dealer..

Maybe someone has a source for grates other than Harman??? I don't know..

Maybe one of the owners of the SF 150 and SF250 will post a photo and a part/model number for the fan. You can adapt just about any fan if you are handy..

That's a good find.. You will get plenty of heat from it.

Go the the 'Venting, chimneys etc' forum and read some of the many threads about distribution of heat.. there is lots of info to read.

The firebrick are standard size, you can buy them at any brick /masonry wholesaler/retailer. about buck apiece.. The rope seals around the doors are standard, available at any wood/coal stove store, or many hardware stores.

Do a search on this site for ' SF150 ' I seem to remember a post about the differences between the SF 150, SF250, and the rare SF350.
