A well-maintained boiler is the heart of a warm and efficient home. Neglecting it can lead to costly repairs, higher energy bills, or even a complete breakdown, especially when you need it most. Whether you have a combi boiler, a gas boiler, or an older system, regular boiler maintenance can extend its lifespan and keep it running efficiently.
In this blog, we will discuss eight essential boiler maintenance tips to help you take care of your boiler and avoid surprises.
1. Schedule an Annual Boiler Service
Just like a car, your boiler needs a yearly check-up. A qualified engineer will inspect key components, clean internal parts, and ensure everything runs safely. An annual boiler service can catch minor issues before they become expensive problems. Also, if you are a landlord, it is your legal responsibility to ensure that your boiler is safe to operate and provides heating and hot water efficiently. However, if you have a boiler cover, check if it includes an annual boiler service; many do!
2. Keep an Eye on the Pressure
Your boiler’s pressure gauge should usually sit between 1 and 2 bars, ideally 1.5. If it’s too low, your heating won’t work efficiently; if it’s too high, it can strain the system.
How to fix low pressure
To fix the low-pressure problem, you will need to repressurise the system by adding water with the help of a filling loop pipe and follow the steps below:
- Locate the filling loop (usually under the boiler).
- Turn off your boiler.
- Open the valves until the pressure reaches 1.5 bars.
- Close the valves and restart the boiler.
- If pressure keeps dropping, you might have a leak—time to call a professional.
To fix the high-pressure problem, you will need to bleed your radiators, which is discussed in detail below.
3. Bleed Your Radiators
If you notice that your radiators have cold spots or take longer to heat up, trapped air could be the culprit. Bleeding is one of the most effective ways to remove trapped air from your radiator. By following a simple step-by-step guide, you can bleed your radiators at home without the assistance of a certified professional.
- Identify which radiators need bleeding.
- Completely turn off your central heating system
- Prepare the area around your radiator for water spillage
- Locate the bleed valve
- Bleed your radiator by inserting a radiator key
- Check your boiler pressure, top it up if needed
- Finally, restart the boiler
- If the problem persists, it might be more complex, and you will need professional assistance.
4. Check for Leaks & Strange Noises
Unusual sounds (like banging or gurgling) or water pooling around your boiler could indicate a problem. Ignoring leaks can lead to corrosion or even carbon monoxide risks.
What to do:
- Inspect pipes and valves for moisture.
- Listen for odd noises when the boiler runs.
- If in doubt, get a Gas Safe engineer to investigate.
5. Keep the Area Around Your Boiler Clear
A cluttered space around your boiler restricts airflow and can be a fire hazard. Make sure:
- No boxes, clothes, or flammable items are nearby.
- The vents and flue are unobstructed.
- This simple step improves efficiency and safety.
6. Consider a Boiler Maintenance Policy
A boiler maintenance policy (often included with boiler cover) gives you peace of mind. It assures you that in case of a sudden emergency or breakdown, you won’t be left alone and burdened by the hefty cost of repairs. This policy typically covers:
- Annual Boiler Service.
- Priority repairs.
- Discounts on parts and labour.
- Customer support
- 24/7 claims helpline
- Assistance of certified gas-safe engineers
7. Test Your Carbon Monoxide Detector
A faulty boiler can leak carbon monoxide (CO)—a silent, deadly gas. Ensure you have a working CO detector near your boiler and test it monthly.
Warning signs of CO leaks
- Sooty stains around the boiler.
- Excessive condensation.
- Headaches or dizziness at home.
- If you suspect a leak, turn off the boiler, open windows, and call an engineer immediately.
8. Don’t Skip the Summer Check-Up
Many homeowners neglect regular boiler servicing, but ignoring this vital maintenance can result in numerous issues. But summer is the best time for maintenance, engineers are less busy, and you won’t be left without heating in winter.
Summer boiler checklist
- Test the heating briefly to prevent seized parts.
- Book a service if it’s due.
- Look for error codes or faults.
Final Words
Your boiler works hard to keep you warm, so a little preventative maintenance goes a long way. From bleeding radiators to scheduling an annual boiler service, these steps can save you money and hassle in the long run.
As mentioned above, a boiler cover policy can protect you from unexpected repairs and sudden breakdowns.
So, stay proactive, and your boiler will thank you with years of reliable service!
