Abstract
A supplemental water heater tank and system features a supplemental tank with an inner vessel surrounded by an outer jacket. The space there between is generally evacuated of air so that the inner vessel is vacuum insulated. The supplemental tank includes water inlet and outlet ports. Water is heated in a water heater and transferred from the upper portion of the water heater tank to the lower portion of the vacuum-insulated supplemental tank through an insulated line and a dip tube that extends between the water inlet port and the bottom portion of the inner vessel. Hot water is withdrawn from the upper portion of the inner vessel of the supplemental tank for use in a home or the like.
