Sensible heat regenerative late night electric boiler

摘要

The present invention heats and accumulates heat medium with excellent heat storage performance by using low-cost late night electricity, and it is effective to save energy and prevent environmental pollution because the heat water can be easily heated by heat exchange of this heat storage medium. In addition, the present invention relates to an sensible heat storage type late-night electric boiler which can extend the life of the boiler by indirect heat exchange using a heat exchange medium and can be made compact in size and compact. The electric heater 24 and the electric heater ( In the heat medium tank 2 filled with the heat medium formed to be heated by 24), the heat medium temperature sensor 22 installed to control the electric heater 24 installed in the heat medium tank 2, and in the heat medium tank 2 The heat-exchanging heat exchange pipe (10) having a heat medium circulation pump (26) provided to move and heat-exchange the heated heat medium, and to receive the heating water The heating water supply pipe 16 and the heating water recovery pipe 18 to circulate the heated heating water formed by passing through the circulating heat exchange pipe 10 so as to exchange heat from the supplied heat medium to the heating water. And a heating water tank (4) provided with a heating medium for operating the heating medium circulation pump (26) to measure the temperature of the heating water in the heating water tank (4) and to supply and shut off the heating medium to the heat exchange pipe (10). It is characterized by a heating water temperature sensor (8).
