  • the present invention relates to a buffer tank for a water heater, and more particularly, to a buffer tank for a water heater which is installed to a water heater so as to prevent a temperature of hot water from rapidly increasing or decreasing.
  • a hot water supply type water heater running water at a low temperature flowed through a running water pipe is supplied to a heat exchanger and is heated by a burner. Then, the heated water is discharged through a connection pipe and is temporarily stored in a buffer tank. The hot water stored in the buffer tank is supplied to a user through a hot water pipe.

  • the hot water flowed from the outside is called ‘hot water’ and the hot water inside the buffer tank 100 is called ‘water’.
  • the hot water flowed from the outside may be hot water at a high temperature which is heated while passing through a heat exchanger in the water heater.

Also, the via holes H 1 formed in the first connection pipe 120 may have each different size and for example, the diameters thereof may gradually increase toward the lower direction.

  • the buffer tank for a water heater according to an embodiment of the present invention includes a storage unit, wherein the storage unit includes long pipes, each of which is connected to the inlet and the outlet, so that water may be easily mixed in the buffer tank. Since water rises upwardly as a temperature of water increases, hot water at a high temperature flowed through the inlet rises to an upper space from a lower space in the buffer tank and thereby, is easily mixed with water existing in the buffer tank.
