Common boiler problems

Boilers are a vital component of many households in the UK, providing heat and hot water on demand. In fact, these usually work so effectively that they are taken for granted, and it is not until a problem or boiler breakdown occurs that we realise how important the boiler is. So what are the most common boiler problems that occur, and how can these be resolved effectively? 

What are the most common boiler problems?

There are a number of common boiler problems that can cause havoc for households and landlords alike. These include:

No Heating or Hot Water:

One of the most frustrating problems homeowners face is a lack of heating or hot water. This issue can be caused by a variety of factors, including a malfunctioning thermostat, low water pressure, a faulty diverter valve, or a broken diaphragm. To troubleshoot, homeowners can start by checking the thermostat settings, ensuring the boiler pressure is sufficient, and resetting the boiler if necessary. If the problem persists, it is advisable to seek professional help to diagnose and repair the underlying issue.

Leaking and Dripping:

Leakages and drips around a boiler are common problems that can indicate a faulty component or a damaged seal. Common culprits include broken pressure valves, pump seals, or corroded pipes. Homeowners should never attempt to repair these issues themselves, as it may require specialized knowledge and tools. Instead, they should promptly contact a qualified heating engineer who can identify the source of the leak, replace any damaged components, and ensure the boiler operates safely.

Strange Noises:

If a boiler starts making unusual noises such as banging, gurgling, or whistling, it may be a sign of an underlying problem. Common causes include air in the system, low water pressure, or issues with the pump or heat exchanger. To alleviate air-related noise, homeowners can bleed the radiators to release trapped air. However, if the noises persist or are accompanied by other symptoms, it is advisable to consult a heating engineer who can diagnose and rectify the issue.

Pilot Light Problems:

Boilers with a pilot light may experience issues with its ignition or flame stability. A pilot light that keeps going out or refuses to ignite can be caused by a faulty thermocouple, a blocked or dirty pilot jet, or issues with the gas supply. Homeowners should follow the manufacturer’s instructions for relighting the pilot light but exercise caution. If relighting does not solve the problem, a heating engineer should be called to inspect and repair the boiler.

Frozen Condensate Pipe:

In cold weather, the condensate pipe of a boiler can freeze, leading to a boiler shutdown or reduced efficiency. Homeowners can try thawing the pipe by applying warm water or using a hot water bottle. Insulating the pipe is also recommended to prevent future freezing. However, if the problem persists, it is crucial to contact a professional to assess the situation and prevent potential damage to the system.
