Stokerman has said that it also has an oversized ring for additional heat output. I can see the dust also, but you aren't buying the dust, it's free!. If you need a great EFM DF520, here is one with no's in Ft Kent, ME, so that is surely more than a 'tank away' for most or us.
Sterlingman lives in the area, so if you wonder if it gets cold, just ask him. The weather channel says it's headed for -23 overnight.

I don't know what a new unit costs, but used units can get to 6K if they are in really good shape. Out of the NEPA the prices are different for the rest of us. Feel lucky if you can find good stuff for less money.
It's -11 at my house right now and my 1962 EFM 520 is silently heating my 3800 sq ft.
A 46 year old boiler working just like a new one; what is there to complain about? Quality is long remembered after the price is forgotten.

10.000 sq.ft. he needs a efm 700 or a 900 if you can find one. A 1300 is overkill

Know where there are any? Tucker......wanna sell yours? Might be one in Albany area I hear. The radiant off the boiler and piping would heat the basement.............Must be an old locomotive up there in maine......that would be smokey with Bit, but a great conversation piece!

Yes, the price of steel soared in June and July, but has since......dropped like a rock. I will be curious to see if prices
follow or will the manufactures keep the $$$. There is some expensive steel in the pipe line, but with the current economic
climate, I do not see people willing to pay for it.
As far as 8000 for a used(how ever little) boiler, the guy is dreaming. Now if oil was $4-$5 per gallon, he could move it
at that price point. But at $2/gal ? I bid on it, needless to say, I did not win it. ;)

It's definitely worth that much to someone who is ready to buy a new one. They will save money. The rest of us have to use older ones.

There was an article in the local paper about a commercial establishment heating with coal. I'll see if I can find it and post it.

I had the highest bid on the 520 in Fort Kent. I talked with the guy who has it for sale and he's sticking to his guns.
I even had a relative( wife's cousing) who lives in Bangor, lined up to drive up there with a trailer and the cash in hand.

No dice. Greg, the owner said he needs to get the $8000 for it and he's still losing money.

I would have made changes in my design before I replaced the unit.

First, the problem is not that the unit is too small the problem is the distribution system probably was not well designed or thought out.

Second, Zoning is critical having more zones, where not all are calling for heat at the same time will save you 20% of the capacity.

Second the 520 does not have enough storage of hot water when the pumps are turned on. The first return of cold water to the unit is probably too much for the unit . The temperature drops and the triple aquastat says it to too cold and shut down the pump until the water temp is up.

Solution add a secondary in line insulated water storage to be used in the winter which is heated by the Boiler at 180 degrees (Not just preheated) this way you have twice the volume of water to circulate. As the season get warmer it can be bypassed if valved properly.

A much cheaper solution than replacing a boiler.

So much for sticking to his 6500.00 that is a solid deal, if the boiler is in fact as new as they claim.
