A speed controller for motors of a solid fuel stove or stoker includes a bidrectional switch, such as a thyristor, to be interposed along an ac power line. The controller operates in a speed control mode for sending reduced power to a stove when a space thermostat is satisfied. The speed control mode may be automatically modulated between minimum and maximum in response to remote sensors, such as a thermistor. The controller may also provide a power-up mode for a predetermined period of time to supply full power to stove motors upon start-up, such as after a power outage. The controller may also provide full power to the stove motors when the motors are being powered by an inverter.
