What to Look 4 in a Used Boiler???

Stoker Coal Boilers automatically feed the coal and have controls and pumps just like any conventions boiler. They are intended to be used as a primary heat and often have domestic hot water coils as an added bonus. They can be set up independently or in dual sytem with your existing oil/gas boiler. They can accommodate both hot water base board or steam plumbing.

Definately look at the domestic coil area for deep rust pockets around the gasket area since this is usually a trouble spot, although even if it looks bad and the price is right for the boiler there are weld on coil plates to fix this problem. As for the stoker mechanism and pot there are a few things to look for there ,but kind of hard to explain unless you know your way around them. Remember that even if there are worn out parts in the stoker mechanism and pot there are readily available for replacement.

Check for a rusted out base $$$$ for a new one and hard to replace once up and running.
Burning coal is definitely worth the extra work involved.
"Good enough" is not good enough.
