The present invention relates to a small electric boiler equipped with a liquid circulation pump with a separately installed driving unit. The invention: enables a user to additionally install a circle heater by obtaining additional space within a water tube by combining the water tube with the circle heater; significantly reduces driving noise generated from bubble generation by reducing the bubble generation by obtaining more surface where the circle heater and water are touched; effectively and smoothly responds to an installation environment by reducing the number of configuration elements for the heater according to a heating environment; and ensures the continuity of boiler usage by changing the liquid circulation pump into other liquid circulation pump when defects are generated in the liquid circulation pump by installing the two liquid circulation pumps inside the boiler. According to the present invention, the small electric boiler equipped with the liquid circulation pump with separately installed driving unit remarkably reduces operation troubles generated from accumulated gas by preventing the gas from being accumulated during a driving process; can effectively and smoothly respond to the installation environment by enabling a user to install the heater by reducing the number of the configuration elements for the heater according to the heating environment; and provides a perfectly waterproof function for the configuration elements such as the driving coil of the circulation pump in which electricity flows. |
