Common Boiler Repair Faults

In the past, our fully qualified and Gas Safe Registered engineers have tackled a variety of gas repairs and boiler repairs. If you have a broken boiler, chances are one or more of the following problems are responsible.

You know that sound that kettles make when they’re filled with boiling water? If your boiler is making banging noises, it is working harder than usual to heat the water. The reason is straightforward. Water contains calcium, magnesium, and other minerals that can solidify into limescale, especially hard water.

When limescale accumulates, it forms a coating on the pipes, which can occasionally obstruct water flow. This causes a new boiler to work harder, hence the noises. Our gas and heating engineers are well-versed in this issue and know how to deal with it.

Boilers can leak from a variety of locations for a variety of reasons. It could be the result of a corroded heat exchanger, loose joints, corroded pipes, loose joints, and so on. Before addressing the issue, the technician must first identify the cause and trace the dripping back to its source.

The thermostat in your boiler system is an important component of the machine that helps to keep the temperature at the desired setpoint. If it’s not working properly, you’ll notice that the water isn’t as hot as you need it to be or that the heating in your home switches on and off at random.

When a thermostat fails, the first step is to ensure that the proper settings are in place. If the problem turns out to be something else, the thermostat may need to be replaced.

Another common issue is the inability of the boiler to heat the water. This problem can be caused by a variety of factors, including a faulty valve, a clogged heat exchanger, or a faulty pilot light. If you are faced with such an issue, you should let our gas safe registered engineer inspect the area and detect the cause.

The circulation of water in the boiler works thanks to high pressure. When there is low water pressure within the system, it doesn’t function well. There may be a leak or something else might be going on. No matter the type of central heating repairs you need, we are here for you, equipped with the best tools and ready to restore hot water flow in an efficient manner.

Condensate pipes are commonly used in newer models to eliminate waste gas. As outdoor temperatures drop during the winter, the risk of your condensate pipe freezing increases. This error will be displayed on the interface of modern devices. If this is the case, the pipe must be heated and defrosted.

This is typically a problem with older models that require a pilot light to ignite. If the light keeps going out, the thermocouple may be faulty. Overall, you should consult with a qualified specialist.

If the system won’t ignite, it could be an electrical issue you are dealing with. Make sure your boiler system is connected properly. You also want to check out other appliances around the home. If they don’t power on either, you should get an electrician to inspect the issue further and provide any electrical work as necessary.

This is a problem if some of your radiators suddenly stop getting as hot as they should. Do you notice any cold patches as you run your hand across the surface? Is the radiator at the bottom cold? This means that the heat is not being distributed evenly as a result of sludge buildup or an excess of air within the devices.

FAQ on Emergency Boiler Repairs

Of course. We can repair different boiler types regardless of their age and we always work hard to deliver a efficient service and make sure your boiler is working safely and efficiently. However, keep in mind that if the appliance is more than ten years old, we may not be able to find replacement parts. This is determined by the heating suppliers and manufacturers.

Most new boilers will last for 10 to 15 years if properly maintained. Having your boiler serviced on a yearly basis can help it last longer.

We strive to be as quick as possible. Given that you are in an emergency, our gas and heating engineers will usually try to visit you the same day you call.

It’s difficult to say because every job is different. The diagnostic will take between 20 and 45 minutes on average. Large-scale repairs may take longer to complete.

If the season isn’t unusually cold, and your area’s electric rates haven’t been raised, but you still have high electric bills, there could be a problem with the entire system. To identify a faulty component, a more thorough investigation is required.

If your radiators have cold spots, it will take longer for them to heat up. They may need internal cleaning, in which case a power flush will be extremely beneficial.
