Common Boiler Problems: Causes and Solutions

Boilers are essential to any residential heating service, providing warmth and comfort during cold weather. Unfortunately, like any mechanical device, boilers can develop problems over time. These problems range from minor issues like low pressure to serious problems like leaks or breakdowns. Here are the most common boiler problems and how you can prevent them

  1. No Heat or Hot Water

    If your boiler is not producing any heat or hot water, there are several possible causes. The first thing to analyze is the thermostat. Make sure it is set to the correct temperature and is working properly.

    If the thermostat is working, check the pilot light. If it is out, relight it according to the manufacturer’s instructions. But if there is still no heat or hot water, the issue may be a faulty diaphragm or airlock. This will require the services of residential heating services.

  1. Low Pressure

    Low pressure in your boiler is commonly caused by a leak somewhere in the system. Assess the pressure gauge to see if the pressure is below the recommended level. This way, you can determine if you need more water in the system.

  1. Radiators Not Heating Up

    If some or all of your radiators are not heating, this could be due to trapped air in the system. Bleeding the radiators should solve the problem.

    Turn off the heating system and wait for the radiators to cool down. Afterward, use a radiator key to open the valve at the lid of the radiator to release any trapped air. Once the air has been released, water should come out. Close the valve and repeat the process for all the radiators.

  1. Strange Noises

    It can be common for boilers to make strange noises, but it could be a sign of a problem if they are loud or persistent. These noises may include banging, hissing, whistling, or gurgling sounds.

    In this case, you must contact a qualified heating engineer to inspect the boiler and identify the cause of the strange noises. Ignoring these noises could lead to bigger problems, so getting them checked out as soon as possible is best.

  1. Leaking Boiler

    If you notice water around the base of your boiler, this could be due to a leak. Several reasons, including a faulty pressure valve, boiler crack, or pump seal, can cause a leak.

    Aside from that, a leaking boiler can lead to water damage to your property and increase the risk of electrical faults. It’s crucial to turn off the boiler and the main water supply and call a heating engineer to fix the problem immediately.

  1. Frozen Condensate Pipe

    If your boiler has stopped working during cold weather, this could be due to a frozen condensate pipe. The condensate pipe is the pipe that takes the water that is produced when the boiler is running outside. During cold weather, this pipe can freeze, causing the boiler to shut down.

    Luckily, you can contact residential heating services to check if this is the issue and to fix it. You can also use hot water or a hot water bottle/heat wrap to warm the pipe, but avoid boiling water.

Final Thoughts
