520 Domestic Hot Water Problems and Other Issues

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.

Thanks everyone that posted! I'm sure I will have more questions in the future.
:D I am glad you got it straightened out.

Don't leave just yet...you made a comment about having problems with the burn plates warping and cracking. Those plates should last a decade, or two...tell us what feed rate and air settings you are using, and how the other controls are set.
