Keeping your boiler running smoothly is vital for a comfortable home, especially during the colder months in Somerset. At Complete Gas Heating, we deal with a wide range of domestic boiler repairs in Saltford, and we’ve seen almost every type of issue imaginable. In this post, we’ll explore the most common boiler repairs our engineers encounter, what causes them, and how you can avoid costly breakdowns in the future.
1. Low Boiler Pressure
One of the most frequent issues homeowners in areas like Keynsham and Saltford face is low boiler pressure. It’s usually indicated on the pressure gauge, and when pressure drops too low, your heating and hot water may stop working altogether. This can happen due to a water leak, a faulty pressure relief valve, or simply because the system has lost pressure over time.
To avoid this problem, check your boiler’s pressure gauge regularly. Most household systems should sit around 1 to 1.5 bar. If the pressure drops frequently, call a qualified heating engineer to check for underlying faults rather than repeatedly topping it up yourself.
2. Pilot Light or Ignition Problems
If your boiler keeps locking out or the pilot light refuses to ignite, it could be due to a faulty thermocouple, gas supply issues, or broken ignition components. Boilers in older properties around Bristol and the surrounding villages often develop this issue over time.
Regular maintenance is the easiest way to prevent ignition problems. During your annual boiler service, an engineer will test ignition parts, clean the burner, and ensure all safety controls are functioning properly.
3. Radiators Not Heating Up Properly
Cold spots or radiators that barely heat can be caused by trapped air, sludge build-up, or circulation issues. This not only affects comfort but can also reduce your system’s efficiency and increase fuel bills. Left untreated, sludge can damage pumps and valves, leading to more significant repairs.
How to Avoid It
Bleeding your radiators regularly helps remove trapped air. For more persistent sludge issues, consider arranging a powerflush. This professional process cleanses your heating system internally, restoring proper flow and improving performance. It’s especially beneficial if your property has an older heating system or if the water in your radiators appears discoloured.
4. Noisy Boiler or Loud Pipes
If you’re hearing gurgling, banging, or whistling, it could indicate ‘kettling’—a build-up of limescale or sludge inside the heat exchanger. This is common in hard water areas like Saltford, Bath, and nearby Chew Valley. Ignoring these noises can lead to serious internal damage and costly repairs.
Prevention is simple: ensure your system is fitted with a high-quality magnetic filter to trap sludge and debris. Regular descaling and water treatment also go a long way toward preventing limescale formation.
5. Thermostat or Control Malfunctions
Sometimes the issue isn’t the boiler itself but the thermostat or heating controls. If your system isn’t responding or maintaining consistent temperatures, the controls might be outdated, incorrectly set, or faulty. Modern programmable thermostats and smart controls provide more accurate temperature management and can even help reduce energy costs.
Updating your controls during a scheduled visit or during boiler upgrades can improve both comfort and efficiency while preventing unnecessary callouts.
6. Leaks and Drips
Leaks can occur from internal components such as seals or pressure valves. Besides water damage, they can indicate bigger problems, such as corrosion. You should never ignore any sign of dripping or moisture around your boiler—it’s important to have it inspected by a professional immediately.
Routine servicing helps spot such issues before they turn into serious faults. Seals and washers can be replaced as part of preventive maintenance, saving you from expensive part replacements later on.
Preventative Maintenance: The Key to Avoiding Repairs
Most of these common boiler problems can be easily avoided with proper care and maintenance. Regular servicing by a Gas Safe registered engineer ensures all components are checked, cleaned, and tested for safety. It also keeps your manufacturer’s warranty valid and contributes to lower energy bills.
At Complete Gas Heating, we recommend an annual boiler service for all homeowners in Saltford and the surrounding areas. This proactive approach helps you catch small issues early and ensures your heating system is ready for winter.
