Can I Convert Old American Standard Severn Boiler to Wood?

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 agree, I'd prefer to burn coal.

If both yourself and the previous owner had significant trouble firing coal, you may want to make sure that the chimney and draft is adequate as well.

I had a American Standard Severn till very recently. I burned wood at the beginning and end of every season with no ill effects. I simply brushed the heat exchanger out every Sat. morning. It also had a sidearm coil for domestic. These should be available without major problems.. It simply functions as a heat exchanger. .If you can't find one, simply buy a new plate heat exchanger and plumb it to a top and bottom plug on the right rear of your boiler. Replacement grates are available in several places in PA that I know about.

I measured the draft, it is -0.04 to -0.05 at the breach, about the same over the fire.
