Roughly one hour per radiator on the system. Descaling: Descaling is needed when a heat exchanger accumulates a significant thickness of calcium on it's surface, enough to insulate the water from the heat source and impair performance. This effect only occurs on heat exchangers that carry fresh tap water.

Vertical-Tube Boiler. In some fire-tube boilers, the tubes run vertically, as opposed to the horizontal arrangement in the Scotch boiler. The VERTICAL-TUBE boiler sits in an upright position, as shown in figure 1-3. Therefore, the products of combustion (gases) make a single pass, traveling straight up through the tubes and out the stack.
