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.
At Protec Heating, we’ve helped countless homeowners across Ealing, Hanwell, Chiswick, and Brentford with emergency boiler repairs. Here’s what you should do before your engineer arrives.
1. Check Your Thermostat
One of the most common causes of boiler issues is a misconfigured thermostat. Before assuming the worst, check that:
- The thermostat is set to the right temperature (above room temperature).
- The thermostat batteries haven’t died (if it’s battery-operated).
- The time and date settings are correct—power cuts can reset smart thermostats, causing heating schedules to malfunction.
If your thermostat seems unresponsive, try adjusting the settings or replacing the batteries. If it’s a smart thermostat, check the app to see if there are any system alerts.
2. Check the Boiler Pressure
If your boiler pressure is too low, it won’t work efficiently—or at all.
- Locate the pressure gauge on your boiler. If it’s below 1 bar, your system may need repressurizing.
- If you feel comfortable doing so, you can top up the pressure using the filling loop (a small, flexible hose under the boiler).
- If the pressure drops again after topping it up, there may be a leak in the system. Contact a heating engineer.
3. Reset the Boiler
Sometimes, simply resetting your boiler can resolve minor issues. Check your boiler’s manual for the correct reset procedure.
- Find the reset button, usually on the front panel.
- Hold it for five to ten seconds, then wait to see if the boiler restarts.
- If the issue persists or an error code appears, note down the code and contact an engineer.
4. Check for Frozen Pipes (in Cold Weather)
In winter, your condensate pipe (which drains wastewater from the boiler) can freeze, causing the boiler to shut down.
- Locate the white plastic pipe that runs from the boiler to an outside wall.
- If it’s frozen, try pouring warm (not boiling) water over it.
- Restart the boiler after thawing.
5. Turn Off the Boiler if You Suspect a Leak
If you see water leaking from your boiler or suspect a gas leak, turn off the boiler immediately.
- For water leaks, turn off the mains water supply if possible.
- For gas leaks, turn off the gas supply and call the National Gas Emergency Helpline (0800 111 999).
6. Make Note of Any Error Codes or Unusual Signs
Modern boilers display error codes when they detect a fault. Before calling an engineer:
- Check the boiler display for any codes.
- Note any unusual noises (banging, whistling, or gurgling).
- Describe any changes in heating performance (cold radiators, no hot water, etc.).
Providing these details to your Protec Heating engineer can help diagnose and fix the problem faster.
7. Check if Your Boiler is Under Warranty or Covered by a Care Plan
If you have a boiler care plan, you may be entitled to priority service and discounted repairs.
- If you’re a Protec Heating Care Plan member, call us for priority emergency service.
- If your boiler is still under manufacturer warranty, repairs may be covered—check your paperwork or the manufacturer’s website.
If you don’t have a care plan, consider signing up for our Boiler Care Plan to avoid unexpected costs in the future.
When to Call an Emergency Boiler Engineer
If you’ve tried these steps and your boiler still isn’t working, it’s time to call a professional. You should contact an engineer immediately if:
- You smell gas or suspect a carbon monoxide leak.
- Your boiler is leaking water.
- The boiler makes loud banging noises.
- The pressure keeps dropping even after topping it up.
- You have no heating or hot water despite troubleshooting.

How to Prevent Future Boiler Breakdowns
A broken boiler is always inconvenient, especially in the middle of winter when you need it most. While emergency repairs can fix the problem, regular maintenance is the best way to avoid breakdowns and unexpected repair costs.
At Protec Heating, we’ve helped countless homeowners in Ealing, Hanwell, Chiswick, and Brentford keep their heating systems running efficiently. Below, we share the best ways to prevent boiler failures and ensure your heating system stays in top condition.
1. Schedule an Annual Boiler Service
Regular servicing is the single most effective way to prevent breakdowns. A professional boiler service:
- Identifies potential issues before they cause a breakdown
- Ensures your boiler is operating efficiently, saving you money on energy bills
- Keeps your warranty valid, as most manufacturers require annual servicing
- Improves safety by checking for carbon monoxide leaks and other hazards
At Protec Heating, our boiler service includes a full safety check, cleaning, and performance test to keep your system in peak condition.
2. Keep an Eye on Boiler Pressure
Low pressure can cause your boiler to stop working, while high pressure can strain the system. Check the pressure gauge regularly to ensure it stays within the recommended range of 1 to 1.5 bar.
If the pressure keeps dropping, this could indicate:
- A leak somewhere in the system
- A faulty pressure relief valve
- Recent radiator bleeding that removed too much pressure
If you notice frequent pressure drops, contact a heating engineer to diagnose the issue before it leads to a full breakdown.
3. Bleed Your Radiators Regularly
Trapped air in your radiators can reduce heating efficiency and put extra strain on your boiler. If your radiators feel warm at the bottom but cold at the top, it’s time to bleed them.
To do this:
- Turn off the heating and let radiators cool down
- Use a radiator key to open the bleed valve slightly until you hear hissing (air escaping)
- Once water starts to drip out, close the valve
After bleeding the radiators, check your boiler pressure—it may need topping up.
4. Insulate Your Pipes to Prevent Freezing
In winter, frozen pipes can cause low boiler pressure or complete shutdown. The most vulnerable part is the condensate pipe, which runs outside and drains acidic water from your boiler.
To prevent freezing:
- Lag external pipes with insulation foam
- Leave heating on low during extremely cold nights to keep warm water circulating
- If the pipe does freeze, pour warm (not boiling) water over it and reset your boiler
5. Use a Smart Thermostat for Better Efficiency
Smart thermostats, such as Hive or Nest, allow you to:
- Set heating schedules to prevent overuse
- Monitor and adjust temperatures remotely
- Improve energy efficiency, reducing wear on your boiler
If you’re considering upgrading your thermostat, our engineers can help with installation and setup for better heating control.
6. Don’t Ignore Unusual Noises or Error Codes
Your boiler will often give warning signs before breaking down. If you notice any of the following, don’t ignore them:
- Banging or whistling sounds (could indicate trapped air, limescale buildup, or a faulty pump)
- Frequent pressure drops
- Water leaks around the boiler
- Error codes on the display
If you spot any of these signs, contact us before the issue worsens.
7. Consider a Boiler Care Plan for Long-Term Protection
Even with regular maintenance, unexpected breakdowns can still happen. A boiler care plan gives you:
- Priority emergency call-outs
- Annual servicing included
- Discounts on repairs and parts
With our Boiler Care Plan, you can avoid surprise repair costs and ensure your heating stays reliable all year round.
