Tarm 502

If you are in need of a more conventional heating solution that requires no power look no further. Unlike an automated stoker boiler these units do not require power to generate heat. They can be set up wiith pumps like a typical boiler or a gravity fed sytem insuring heat during power failures. Models include many New Yorker coal boilers, EFM WCB-24 and others. Some of these units can also burn wood.

I just bought a 80s vintage tarm 502. Are there any tarm users out there ? I would like to burn coal in it . It has shaker grates and manual says it can use wood/coal/oil/gas/or electric . Is this a good coal burner ? or should I stick with wood ? Any opinions would be helpfull, Thanks

Can you post a photo of the stove, the firebox and grates??

Even if you don't burn coal in it. You have a very good wood boiler.

Tarm is probably the best.

I'm familiar with them, at least one member has one, I know as I moved it. :)

They are one of the best wood burners on the planet as they are wood gasification, they consume all most all the volitiles and creosote and emit very little smoke. For that process to work properly they need to be plumbed properly, most often with the supply feed from a recirculating loop to keep the boiler temps up. They burn coal well but can be tricky as it has a firebox that is off the beaten path for anthracite. I know one thing you want to check is the baffle between the oil and wood chambers. They are known to rot away, parts are reasonable and available. To burn coal it should have a series of stubby rocking grates that rock in an alternating fashion with a large lever on the right. The draft control is an interesting natural draft design. It is a European design and I was impressed with its construction.

Now tell me, what did you pay for it? :)

Sold for about $5,000 new when I sold them, would be higher today
Coal grates were extra

Yes, that boiler has coal grates in it!

And, yes, it can be a learning experience to burn coal in a 500 series (or 400 series, which is an add-on identical), BUT it does burn and burn well. It has to do with the way you bank the coal, more toward the front in this case. In the rear it should not be piled as high as the opening where the gases exist. There is a optional piece called a coal baffle, which is an upright piece installed in the read (two grates are removed) - this makes it even easier to burn coal, but it may not be available any longer. Check with tarm.

The little swing piece under the grate is designed to deflect air up through the coal bed so it does not all bypass the coal.

The Excel is a completely different boiler. A 502 is a natural draft system, while an Excel is a forced draft unit with higher wood efficiency due to the ceramics and design. Yes, Gabe over at Preston probably has a manual. He is away on vacation now, but will return in about 10 days.
Got that from a quick search on the net.

I paid $500 for it. I had to "settle" :( for this one because I used some of the funds I had set aside for a used AA-130 transporting father back and forth to hospitol (he has cancer but is on rd to recovery now) :) . It is in excellent condition . Baffles seperating oil side and the grates are all in excellent shape too.

If the baffle is good, it means the oil side was rarley used which is a good sign. The link the Mayor provided will be a good resource for you (I think that is one of cokehead's (a member here) threads). There are a lot of TARM owners and dealers on that site including the original owner of TARM USA IIRC. Try and get the coal baffle mentioned as it makes burning anthracite an easier task, it goes in the rear of the firebox. There are several TARM threads over there, do a search and you will have a boatload of info. Also there is a thread of mine on moving one, you may want to read that one. The thing weighs 1400# and is tall and very narrow, it will be a treat. :) Be sure you get all the pieces of the recirculating loop if you can, pumps, valves, ThermoVar, etc. Those peices can get very pricey, without them your wood burning efficiency will go into the toilet and it will smoke and load up w/creosote (like a real wood burner :lol: ).
