The hot water circulation accelerator for an electric boiler is installed that a circulation inducer is installed between a hot water supply tube and a connection tube of a heating tube, the inducer compressing hot water by an intake to inject it as high-pressure vapour and thus rotate a circulation fan due to the vapour injection force, hot water is forcibly circulated to the heating tube, an air outlet is formed in a casing of the inducer to remove air bubbles produced by forcible circulation of hot water, and air is discharged through the air outlet with a slight amount of hot water.
