Homeowners with oil-fired water heaters have discovered they have a reliable, low-cost access to virtually unlimited amounts of hot water. Oil-fired water heaters have high recovery rates - they can heat large amounts of water quickly. Oil-fired water heating systems come in two categories: direct, where the water is heated directly by the heat of the heating oil flame; and indirect, where the domestic water is heated by hot water from the boiler.
