Softening the cold water supplied to the water heater, will gradually dissolve hardness scale buildup from within the WH, increasing hot water hardness somewhat until there is no scale remaining.
Oil fired WHs are typically configured similar to gas WHs with the burner located directly below the water tank. The bottom of the water tank then functions as a heat exchanger with a vent flue passing through the center of the tank to a chimney or exhaust vent connector at the top.
Hardness scale will accumulate mainly on the hottest components, including the tank bottom and around the flue pipe. The scale will act as an insulator, lowering heating efficiency and increasing the burner run time and fuel expense.
