Common Boiler Issues and Solutions

Boilers are complex machines that can experience a variety of issues that may affect their performance. Fortunately, many common boiler issues have straightforward solutions. In this section, we will explore some of the most common boiler issues and offer solutions to help you get your boiler back in working order.

Low Pressure

If your boiler’s pressure is too low, it may not be able to heat your home efficiently. Low pressure can be caused by a variety of factors, including a leak in the system or a faulty pressure relief valve. To resolve low pressure, start by checking your boiler’s gauge to see if the pressure is below the recommended range. If this is the case, you may need to refill the system with water or replace the pressure relief valve.

No Heat or Hot Water

If your boiler is not producing any heat or hot water, it may be due to a broken airlock, a faulty thermostat, or a problem with the pilot light. To diagnose the issue, start by checking the boiler’s pilot light. If it is out, try relighting it according to the manufacturer’s instructions. The pilot light is not the issue, check the thermostat to see if it is set to the correct temperature. If neither of these solutions work, you may need to call a professional to repair your boiler.


Kettling is a problem that occurs when limescale builds up inside the boiler’s heat exchange. This can cause a rumbling or banging noise to come from the boiler. To resolve kettling, you may need to flush the system to remove any limescale buildup. Keep in mind, persistent kettling could signify a serious problem like a broken heat exchanger, so enlist a professional to inspect your boiler if the issue continues.

These are just a few of the most common boiler issues that homeowners may experience. If you are unsure of how to resolve a problem with your boiler, it is always best to contact a professional for assistance. By properly maintaining your boiler and addressing issues as soon as they arise, you can ensure that your home stays warm and comfortable throughout the winter months.

How to Fix a Broken Boiler in London

If you’re based in London and your boiler has broken down, don’t panic. Here’s a step-by-step guide on how to fix a broken boiler:

  1. Check the thermostat: Ensure that the thermostat is set to the desired temperature and is functioning correctly.
  2. Check the power supply: Ensure that the boiler is receiving power by checking the fuse box.
  3. Check the pressure: Low pressure can cause a boiler to stop working. Check the pressure gauge and repressurize if necessary.
  4. Check the pilot light: If the boiler has a pilot light, check that it is lit. If not, follow the manufacturer’s instructions to relight it.
  5. Check for leaks: Check for visible leaks around the boiler and the pipes leading to and from it. If you see any leaks, contact a qualified plumber to fix them.

Boiler Maintenance and Common Problems

Regular boiler maintenance is essential to ensure your boiler is functioning correctly and efficiently. Neglecting maintenance can result in problems that can be costly to repair. In this section, we will discuss the importance of boiler maintenance and provide tips on how to keep your boiler in working order. We will also address common boiler problems and how to troubleshoot them.

Importance of Boiler Maintenance

Regular boiler maintenance can help to prolong the lifespan of your boiler, increase its efficiency, and prevent costly repairs. You should get a qualified engineer to service your boiler at least once a year. During a service, the engineer will check the boiler’s components, clean it, and make any necessary repairs.

You can also perform some simple maintenance tasks yourself, such as checking the pressure gauge, ensuring adequate ventilation, and bleeding your radiators. These tasks can help to prevent issues from arising and keep your boiler working efficiently.

Common Boiler Problems

While regular maintenance can help to prevent problems from occurring, some issues may still arise. Here are some of the most common boiler problems:

If you’re facing any of these issues, we recommend contacting a qualified engineer for repairs. Attempting to fix the problem yourself can be dangerous and may cause additional damage to your boiler.
