Water-Heater
Among other items in the basement, the water-heater was unique. This cast-iron stove stood about 3 feet in height and was perhaps a foot in diameter. It was green in color. The double walled construction allowed water to circulate around the inner firebox.Fuel was a special fine crushed coal that was added with its own special scoop. I don't remember where the supply was kept. I had the early responsibility to add a scoopful at times to insure hot water as needed. The ashes were removed in the usual manner.
I was impressed that it was a separate unit from the furnace.
