Common Boiler Issues That Lead to Emergencies
A boiler breakdown often feels sudden, but in most cases, the signs have been there for a while. Understanding the most common boiler problems can help you act quickly and, in some cases, prevent a complete failure.
At Protec Heating, we’ve handled thousands of emergency call-outs in Ealing, Hanwell, Chiswick, and Brentford, and we’ve found that most boiler failures fall into a few key categories. Below, we’ll outline the most frequent issues homeowners face and what may be causing them.
1. No Heating or Hot Water
This is the most obvious and stressful issue, especially in the middle of winter. Several factors can cause a sudden loss of heating or hot water, including:
- Low boiler pressure
- A faulty thermostat
- A broken diverter valve (which controls whether hot water goes to radiators or taps)
- Airlocks in the system
What You Can Do
- Check if the thermostat is set correctly and hasn’t been accidentally turned down.
- Look at the pressure gauge—if it’s below 1 bar, it may need repressurizing.
- Try resetting the boiler following the manufacturer’s instructions.
2. Low Boiler Pressure
Boiler pressure should typically be between 1 and 1.5 bar when the system is cold. If it drops too low, your boiler may shut down to prevent damage. Low pressure can be caused by:
- Leaks in the system
- Bleeding radiators (which can release system pressure)
- A faulty pressure relief valve
What You Can Do
- Check the pressure gauge on your boiler. If it’s low, follow the instructions in your manual to safely top it up using the filling loop.
- If you suspect a leak, do not attempt repairs yourself—contact a Gas Safe registered engineer.
3. Strange Noises Coming from the Boiler
Boilers should run fairly quietly, so if you hear loud banging, whistling, or gurgling sounds, there’s likely a problem.
- Banging or clanking – could indicate trapped air or limescale buildup (known as “kettling”).
- Whistling – often caused by a blocked pipe or a faulty thermostat.
- Gurgling – may suggest trapped air or frozen pipes.
What You Can Do
- Try bleeding your radiators to remove air pockets.
- If the problem persists, call a professional to inspect for blockages or limescale buildup.
4. Boiler Keeps Turning Off
A boiler that constantly switches off could indicate:
- Low pressure
- A faulty pump (which isn’t circulating water properly)
- A blocked or frozen condensate pipe
- A thermostat issue
What You Can Do
- Check your thermostat settings.
- Look at the pressure gauge and top it up if needed.
- If it’s especially cold outside, check if your condensate pipe (the plastic pipe running from your boiler to the outside) is frozen. If so, try thawing it with warm (not boiling) water.
5. Water Leaks from the Boiler
Water leaking from your boiler is never a good sign. It could be due to:
- A broken internal component (such as a pump or pressure valve)
- Corrosion in the system
- A poorly fitted connection
What You Can Do
- Turn off the water supply to prevent further damage.
- Do not attempt to repair leaks yourself—contact a professional immediately.
When to Call a Heating Engineer
While some minor issues can be resolved with basic troubleshooting, certain problems require immediate professional attention, including:
- Gas smells or suspected carbon monoxide leaks (leave the house and call the National Gas Emergency Helpline at 0800 111 999)
- Major water leaks
- Persistent low pressure despite topping up
- Error codes on the boiler that won’t clear
If you’re experiencing any of these issues, contact Protec Heating for fast and reliable emergency boiler repair in Ealing, Hanwell, Chiswick, and Brentford.
Essential Steps to Take Before the Engineer Arrives
When your boiler stops working, the natural reaction is to worry—but taking a few key steps before the engineer arrives can help speed up the repair process and, in some cases, even get your heating back up and running. While some problems require professional attention, basic troubleshooting can sometimes resolve minor issues or at least help you describe the problem more accurately to the engineer.
