The device reduces the amount of fuel used by a heater of a heating system by delaying a signal from a temperature sensing control device, such as a thermostat, to the heater. Any residual heat of the heater is thereby dissipated before the heater is activated by the thermostat. The device may be powered by mains electricity and include a multiple digit display 22 that indicates the number of heating cycles undertaken by the heater. Light emitting diodes may be used to give operational information about the device, with LED 12 indicating the device has power, LED 16 indicating when the device is delaying activation of the heater, and LED 27 flashing to indicate normal operation of the heater. The device may include an electrical inlet plug 1 and electrical outlet socket 2 wherein, in use, the plug receives wiring of the thermostat and the socket is connected to wiring of the heater. The device may include a microprocessor system monitor in combination with an audible alarm that sounds if the device is at fault so that wiring of the thermostat and heater may be disconnected from the plug and socket respectively and connected to one another to bypass the device.
