The fluid heater system has a flow rate controller to control the flow rate of fluid through the conduit. The fluid heater is controlled using a controller operatively connected with the flow rate controller to vary the flow rate of fluid through the conduit reliant on the output from the sensor to achieve a desired target temperature of the fluid leaving the conduit.
