The invention discloses a temperature control method of a central supply rapid water heater. The temperature control method comprises the following steps that S1, a control device presets the target temperature Ts of domestic hot water and initializes a throttling valve and a heating water circulating pump; s2, the control device detects the flow phi (t) of the domestic hot water; whether the flow phi (t) reaches alpha L/min or above is judged; s3, if yes, the control device detects the actual temperature T9 of the heating water; whether the difference value delta T between the actual temperature T9 and the target temperature Ts reaches mK or above and whether the flow change value delta phi reaches betaL/min or above are judged; s4, if yes, the state of the throttling valve is fully open, and meanwhile the output power P of the heating water circulating pump is calculated through the relational expression P = f (phi) of the output power P and the flow phi (t); and S5, the control device collects the actual t
