How does a person open a up and clean a boiler of scale, so it burns more efficiently? My Raypack is about the 1958 vintage, and I sense it not reaching a hot enough temperature to efficiently help my in slab hydronic heating system. I know it's time to replace, but would like to be able to remove some scale, and get a little better efficiency for the rest of the winter.
