Safety energy saving water heater

The utility model is used for providing hot water, in particular to a safety energy saving water heater. Aiming at the defects that the existing electric water heater has high power consumption and electric shock hazard, and the gas water-heater has the toxic hazard of gas leakage and high fuel gas cost, disclosed is the safety energy saving water heater. The safety energy saving water heater of the utility model comprises a water inlet pipe, a water outlet pipe, a shower nozzle connected with the water outlet pipe and a heating device positioned between the water inlet pipe and the water outlet pipe. The power source of the heating device is transmitted from the secondary edge of a single phase step-down transformer. The safety energy saving water heater of the utility model has reasonable structure and the cold water heating mode is changed into direct-current type. The safety energy saving water heater uses low-voltage heavy-current to do work and a heat insulation barrel is canceled. The safety energy saving water heater can be used when is heated and the safety energy saving water heater decreases energy consumption effectively.
