Gas Boilers
What you need to know about gas boiler servicing.
Gas boilers should be serviced regularly, usually once a year. Having a gas boiler serviced ahead of the winter can save you money and prevent costly repairs.
There are a number of signs that indicate a gas boiler service is needed:
- An irregular or yellow boiler flame.
- Stains or smoke marks appearing on or near the appliance.
- Hot water has limited flow or is less hot than it should be.
- Boiler refilling and/or overheating frequently.
- Excessive noises from the boiler fan.
- The boiler pilot-light repeatedly going out.
- A drop in pressure.
A Gas Boiler Service will:
- Ensure the gas & electricity supplies are isolated.
- Clean the burner/injector(s).
- Clean the pilot/injector.
- Clean the flue-ways, including the draught diverter & heat exchanger.
- Clean & adjust the ignition components.
- Clean flame supervision components.
- Clean, lubricate & adjust controls.
- Repair any gas leaks.
- Check all disturbed gas connections.
- Check all boiler seals & joints.
- Check there are no obvious signs of damage to the wiring.
- Re-set the burner operating pressure to that on the data label/plate.
- Test open flued boilers for spillage.
- Re-check the flame supervision device operation.
