A heating system employs a thermostat fuel control device and a safety fuel control device, such as a safety valve retained against a closing bias wherein a bulb contains an expandable fluid for releasing the safety valve, responding to an overheat condition of the heating system. The safety fuel control device can be employed as an addition to the normal recyclic cutoff.
