SECONDARY STORAGE OF HOT WATER FOR WATER-HEATER Russian patent published in 2015 - IPC F24H1/00 

FIELD: energy engineering.

SUBSTANCE: invention relates to heat power industry and can be used in water heaters, which can provide hot water supply in sufficient volume with simultaneous balancing fluctuations of temperature of hot water. The secondary storage of hot water for water-heater is proposed, comprising: a hollow outer tank, a buffer storage mounted around the central axis of the inner volume of the outer tank for temporary storage and supply of hot water, a coil for heating water, placed between the outer tank and the buffer storage, having an inlet pipe at one end, brought from outside through the housing of the outer tank, and having at the opposite end an outlet pipe communicating with the buffer storage, a first water supply channel connected to the coil for heating water through the inlet pipe, a first discharge channel of the buffer storage, the second water supply channel, in which the coolant is supplied through the inlet pipe on one side of the outer tank for heating water in the coil, coming through the first water supply channel and coming out through the first discharge channel and the second discharge channel having an output through the pipe at the opposite side of the outer tank for draining the coolant entering through the second water supply channel.

EFFECT: improvement of the design.
