Today's heating systems are significantly more efficient. While older equipment can waste up to 50 per cent of the energy used, newer models have reduced that figure to as little as six per cent. But if a new system is not on the horizon, helping your existing system stay in tip-top shape can help.
Your furnace or boiler needs periodic tune-ups. A regular maintenance program is relatively inexpensive. It can extend the life of your heating equipment and help it operate at maximum efficiency.
While there are differences in the design and operation of different gas boilers and furnaces, the following should be included in a routine tune-up:
- Clean the burner, combustion chamber, and heat exchange surfaces.
- Check the colour of flame. It should be blue. A yellow or orange flame indicates that the gas is not burning properly, and the equipment should be adjusted by a professional.
- Check fan belts and blowers and adjust loose belts.
- Check safety controls.
- Check the barometric damper operation.
- Check thermostat operation and location.
- Check the thermocouple.
- Check the chimney base and flue pipe.
- Adjust pilot and burner (if applicable).
- Inspect and replace all filters.
- Lubricate all motors.
- Check the vent terminals for blockage.
