Converting Boiler back to coal from oil
It would help if you mentioned the make and model of the boiler. Were any of the old coal parts retained in the basement (grates and shakers)? Since you live in New York you will be burning anthracite coal (rice or buckwheat size). I would look to buy one of the automatic stoker models of coal boilers on the market. Look at the Keystoker models which are made in Pennsylvania.
also look at the Electric Furnace Man (EFM) coal boiler with the automatic stoker. It has the option of adding an oil burner kit for summer usage. In the past the hand fired coal boilers would be banked so that the fire did not go out during the night. If it was very cold outside you had to get up early and shovel coal to get the boiler up to speed. During the day, someone has to be available to hand-fire a coal boiler. I think you would be much happier with a modern coal boiler with an automatic stoker. You would use less coal. You might want to look here for an EFM dealer in your area as you did not specify where in the Hudson Valley you are locted.
