Description

The hot water in the boiler is less dense than the water in the storage tank and the water in the conduit connecting the boiler and the storage tank. Due to this density difference, the hot water tends to rise to a higher position in the device and moves towards the storage tank. On the other hand, the cold water tends to descend in the device. Thus, the water in the storage tank becomes warm with time, while the boiler needs energy to heat the descending cold water.
WO 98/51970 discloses a stand-alone non-pressurized hot / cold water dispenser, which comprises a dispenser body with a water container that can be filled by a reverse water bottle that can be placed on top of the dispenser body; A check valve provided in a hot water tank, a pipe for supplying water from the water container to the hot water tank, and the heated water in the hot water tank flows back to the water container or the cold water tank And an expansion chamber connected to the hot water tank, which allows expansion of the hot water and maintains the water in the hot water tank at substantially atmospheric pressure. It is a waste. This dispenser, however, is not capable of thermal insulation.
