Boiler

Every home needs a working boiler because it provides hot water and central heating, especially in the winter. When a boiler stops working, the entire house is affected. You should know the common ways for a boiler fix to avoid having to contact a heating engineer.

Most of the time, it becomes expensive to make calls for an emergency boiler breakdown. 

This post will go through how to inspect and fix minor boiler issues by yourself and perform simple troubleshooting to solve typical problems. But it is highly recommended to consult an expert engineer in case of any significant problem.

1. The Boiler Repeatedly Turns Off

This could be brought on by several problems, such as an issue with the thermostat, low water pressure, or a lack of flow.

Check the pressure and thermostat. If bleeding the radiators, repressurizing the system, and setting the thermostat doesn’t work. Call a certified boiler specialist to resolve your boiler problem. 

2. Cold Radiators

Air in the central heating system is most likely to blame if all of your radiators are not working or are just partially warm.

Bleed the radiators. If there is no progress, the system may need flushing.

3. Low Pressure of Boiler

You may have a problem if the pressure sensor on your boiler reads less than one.

Check the system for leaks. You can do a boiler fix yourself; try to re-pressurize the system if there are no leaks by carefully following the directions in the owner’s manual that came with your boiler. 

4. Leakage in Boiler

The causes of leaking depend upon where the leak or drip is coming from. A faulty part can cause your heating system to leak. Corrosion can potentially be the cause.

5. Frozen condensate pipe

A pipe that transports condensation (acidic water) to an exterior drain is included with a condensing boiler. A condensation pipe may occasionally freeze in cold weather, making noise in the pipes. A fault code on your boiler should let you know when the condensation line is frozen.

You can find instructions for securely defrosting a condensation pipe online.

6. Noisy boiler 

Air in the system is most likely to be the cause if your boiler is vibrating, pounding, gurgling, or making a whistling sound. A faulty pump or low water pressure could also be the reason. A boiler or heating system noise should not be ignored because it likely signifies a problem. The possible fault will change depending on the kind of sound and its source.

If your boiler is buzzing or vibrating, adjust the settings or check the connectors. If you’re unsure, make sure to contact your supplier because the noise could be a sign of a more severe problem.

7. The pilot light malfunctions

The pilot light is the small gas flame inside your boiler. A persistent issue, the pilot light going out, could be brought on by something as simple as a draught blowing the flame out or a buildup on the gas nozzle.

A safety feature in the boiler is called a thermocouple; it monitors the temperature change of your pilot light so it can determine if it goes out. Alternatively, the gas supply could be interrupted by a faulty thermocouple.

If your gas supply is working properly, consider relighting the pilot for a boiler fix by reading your boiler’s operator’s manual. 

Because new boiler systems are not designed with pilot lights, this problem is more prevalent in older boilers. Getting a new boiler installed can be worthwhile if the problem with your pilot light doesn’t go away.

A checklist To Keep Your Boiler Working Properly

However, performing a few checks daily or weekly could be hectic. Still, it would help keep your boiler in proper working condition throughout the year.

• Check whether or not the pressure and temperature gauges are showing readings within the specified limits.
• Check your boiler for proper ventilation and ensure it is adequately ventilated.
• Inspect that the combustion air opening does not have a blockage.
• Always check the area around and under your boiler to see if there are any leaks.
• You should also check the other things like the condensation drain line, drain trap and drain system. 
• Notice any disturbing and unusual sounds in the boiler.
• Check for any error codes.
• Confirm that there is no blockage or debris near the termination vent.
• An inspection of the combustion air piping and the flue vent gas piping should be performed. In the inspection, your primary focus should be checking for leaks and blockages.
• Inspect the discharge pipe and boiler relief valve for any leakage.

If all the given checks do not show any error, you should be satisfied that your heating system will be with you for a long time. 

Wrap-up Note

An efficient boiler serves as the heart of a home, responsible for supplying hot water and heat that enables you to create a comfortable living space.

Maintaining your boiler between yearly inspections could help avoid costs for boiler fixes, malfunctions, and emergency repair calls. However, you should always get the help of a professional engineer if any boiler issues occur that you cannot rectify  yourself!
