ABSTRACT:
A hot water boiling apparatus includes a hot water storage tank. The storage tank has an inner tank storing water therein, an outer tank surrounding the inner tank, and a vacuum heat insulation layer defined between the inner and outer tanks and surrounding the inner tank. An electrically heated bubble pump unit is arranged outside the storage tank and used for drawing water from the inner tank through a water supply port formed at the bottom of the inner tank and, after heating the water, supplying it into the inner tank through a hot water supply port formed at the top of the inner tank. First and second connecting pipe respectively connect the bubble pump unit to the top and bottom water supply ports of the inner tank. The portions of the connecting pipes extending through the vacuum insulation space are oriented horizontally to minimize convection heat losses. The portion of the connecting pipe which passes through the vacuum heat insulation space is oriented horizontally.
