When to Service Your Boiler

If you're not sure when the last time your boiler was serviced, it's probably been too long. A boiler service should be conducted at least once a year, preferably in the fall before winter sets in. Servicing your boiler regularly can help extend its lifespan and prevent costly repairs down the road. If you're ever unsure about anything, it's always better to err on the side of caution and contact a specialist in order to ensure your boiler is running safely and properly.

Things to Look Out For

Not sure if your boiler needs a service? Here are five signs to look out for:


1. Your Boiler Is Making Strange Noises

If you notice your boiler starts making strange noises, it's definitely time for a service. Boilers usually operate quite quietly, so any new noise is cause for concern.

Possible causes of strange noises include:

  • kettling (usually a build-up of limescale in the boiler)

  • air in the system

  • loose components

2. The Pilot Light Is Flickering Or Has Gone Out

If the pilot light on your boiler is flickering or has gone out, it's a sign that there is something wrong with the gas supply. This is a potentially dangerous situation and should be addressed immediately by a qualified engineer.

Possible causes of a flickering pilot light include:

  • a faulty thermocouple (a safety device that measures the temperature of the pilot light)

  • dirt or debris in the burner

  • low water pressure

3. There Is Water Leaking From The Boiler

Water leaking from your boiler is a sure sign that something is wrong. Water leaks can be caused by a variety of issues, including corrosion, wear and tear, or a build-up of limescale.

Other possible causes of water leaks include:

  • a faulty pressure relief valve

  • a cracked heat exchanger

  • loose pipes or fittings

4. The Radiators Are Not Heating Up Evenly

If your radiators are not heating up evenly, it could be a sign of a problem with the circulation pump or boiler pressure. This is something that should be checked by a professional.

Possible causes of uneven radiator heat include:

  • a build-up of sludge in the system

  • air in the system

  • a faulty thermostat

  • a faulty circulation pump

  • low boiler pressure

5. The Hot Water Is Not As Hot As It Used To Be

If you've noticed that the hot water from your taps is not as hot as it used to be, it could be a sign of a problem with the boiler itself.

Possible causes of lukewarm water include:

  • a build-up of limescale in the boiler

  • a faulty thermostat

  • low boiler pressure

The Bottom Line

Servicing your boiler regularly is essential to keeping it running smoothly and efficiently. If you're experiencing any of the problems listed above, or if it's been more than a year since your last boiler service, don't hesitate to contact us. Our qualified engineers are always happy to help!
