Our boiler is rarely thought about except when we use it to heat water and supply hot water. There can be chaos in the house if the boiler breaks down. Families wished they knew how to solve boiler problems at that time. I understand your situation ha :((
Problems with the boiler can be very annoying, especially in the winter. Despite regular maintenance, boilers can experience a wide range of issues, including leaks and cold radiators. It is fortunately not difficult for a registered engineer with Gas Safe to identify and resolve most of the most common problems.
The following are the top ten most common boiler problems across all types of condensing boilers.
#1. A leaky faucet or a dripping pipe
If you notice any excess water surrounding your boiler tank or pipe connections, is it because of excess water? Boiler tanks frequently leak and drip. As boilers age, they can accumulate rust. Skill can be lost when this occurs.
Old parts, aging seals, pressure valves set too high, a system constantly over-working, and corrosion of pipes can cause leaking or dripping. They should contact a local heating contractor for assistance in determining the cause of the leak or drip. To determine where the leaking water is coming from, they will examine the boiler tank and pipes.

#2. Pressure drop in the boiler
A boiler’s built-in pressure gauge will usually show you whether its pressure is low. If possible, you should set your boiler’s pressure at 1.5 bar. This number must be above 1. Otherwise, your boiler won’t work correctly.
There are many reasons why boiler pressure is low, including system leaks, recently bled radiators or failed components. You may wish to check for visible signs of leakage to identify the problem, but do not remove the boiler’s casing. Please get in touch with a Gas Safe registered engineer if you find a leak.
You could repressurize your boiler if you feel comfortable doing so if you cannot find a leak. Here is the step-by-step guide that will demonstrate how you can do it.
#3. Pipes filled with frozen condensate
The freezing of condensate pipes is a common issue in the winter. We discharged water generated by condensing boilers outside through a plumbing system in the boiler. In low temperatures, the condensate pipe may freeze, which forces an automatic shutdown of the system as a precaution.
You can thaw frozen condensate pipes by pouring warm water on them. By doing so, the boiler will restart again after the wastewater has exited the tube. Please find out how to resolve a frozen condensate pipe issue in our guide.
- Please check your plumbing service strategy.
#4. Irrigation Leaks
Several factors can contribute to the leakage of water from a boiler. It would be best to find out where the water is leaking from to determine the cause. Usually, it occurs when an internal boiler component fails, such as a pressure valve or a pump seal. A leak originating from a pressure valve indicates high boiler pressure. The pump seal, however, requires replacement if it’s leaking.
Sometimes, the boiler leaks from around the tank or pipes. When corrosion occurs, or fittings are not correctly attached, this happens.
#5. Noise from the boiler is unusual
The boiler hums typically when it is running. Having said that, if the sound gets louder and more unusual, this could indicate an issue.
There will be either a whistle or gurgle from the boiler. Boilers whistle when trapped air is trapped within the pipes or in the boiler. A radiator has to be bled to resolve this issue. Gurgling boilers indicate a frozen pipe somewhere that is interfering with water flow. To locate the frozen pipe and decide the case, you may need to call a gas safe engineer. That should eliminate the noise.
#6. The pilot light not working
Pilot lights in boilers keep the burners lit with a small blue flame. Boilers won’t function effectively if they go out continually. Usually, this happens when a thermocouple breaks, thereby interrupting gas flow.
Check the gas supply for issues before attempting to relight the light. Gas stopcocks being on but boilers not receiving gas are signs that an engineer is needed. Following the instructions in the manual will allow you to reignite the pilot light on your own.
#7. Switching off the boiler is a constant problem
In the long run, a boiler may randomly shut off if left unattended. There are several reasons why this may have happened, including:
- The system is trapped with air
- The boiler has low pressure
- Boiler pressures are high
- There is a problem with the thermostat
- Sludge and debris accumulate inside the pipes
Whether one or more of these faults has caused your boiler to keep turning on and off could be the cause. Depending on the severity of the problem, a qualified engineer may suggest a repair or a new boiler.
#8. Boiler breakdown
If any of the above issues aren’t addressed, a boiler breakdown can occur. Call an engineer registered with Gas Safe immediately in this case.
A helpful tip for regular boiler owners: if you are only using a heating boiler, you may be able to use an immersion heater as a backup heater.
A boiler can also fail due to old age and inefficiency. You will heat and provide hot water with a new boiler if you currently own an old, inefficient boiler.
You can also save money on your energy bills* with a modern, energy-efficient boiler!
#9. The water is hot, but there is no heat
A faulty diverter valve can cause your hot water to stop working while your central heating continues to work.
Check that the thermostatic valves of your radiator’s arena aren’t closed first. Check your boiler settings, make sure it turned the central heating on. This varies per boiler model, but many boilers have an on/off button for the heating.
#10. Thermostat Issues
A faulty thermostat can sometimes give rise to poor performance. You may notice that a thermostat is sending the wrong signals because your room climate is incorrectly sensed.
Our technician will need to troubleshoot your thermostat before coming to your home. Please turn on the power supply and make sure it is working. Ensure that the timer and clock settings on the device are correct. Installing a new one is sometimes necessary.
Many problems can arise with boilers, and there are many factors to consider for each situation. You might be able to troubleshoot your boiler and get it back up and running in no time if you have heating issues. It is dangerous to work with boilers, however.
I highly recommended that you contact a heating contractor with experience repairing and replacing boilers. If there’s another problem with the heating or plumbing, we can diagnose and fix it immediately!
We can help you if you are experiencing boiler problems and need your house to be comfortable and warm again.
