Boiler Repair Wandsworth: Common Problems in Semi‑Detached Homes

If you live in a semi-detached home, your boiler repair needs in Wandsworth can be a little different from those of someone living in a flat or a terraced property. The layout of the house and the age of the heating system can both affect how the boiler performs, especially if your system has been in place for many years.

In these homes, you may even notice a few boiler issues that tend to come up more often than others. Here are some of those problems you should know about:

Low pressure

If the pressure gauge drops below 1, your boiler may struggle to ignite or stop working altogether.

 

When that happens, it’s a good idea to check around your home for any signs of leaks or damp patches. Take a look at your radiator pipes and any valves connected to the heating system as well. Your boiler can lose pressure for a few different reasons, such as a faulty expansion vessel or small leaks somewhere in the system. In some cases, the pressure can also slowly drop over time without a major fault.

 

To restore the pressure, you can try refilling the system until the gauge rises slightly above the 1 mark. Not sure what to do? You can also call our plumber from Wandsworth and leave it to them. At the same time, we will check the safety relief pipe around your property for leaks that may indicate an internal fault.

 

Pilot light issues

 

The pilot light is the small flame that stays lit inside your boiler so it can ignite the main burner when heating is needed. You might notice that it’s prone to more problems as your boiler ages.

 

If the pilot light goes out, your boiler will stop producing heat or hot water. This can be caused by several things, including a blockage or a strong draught that extinguishes the flame. However, it could also be caused by a failing thermocouple, the safety component that detects the pilot flame.

 

Before calling for boiler repair in Wandsworth, check whether other gas appliances in your home are working properly. This helps confirm whether the issue relates to your gas supply. You can also review the manufacturer’s instructions to see how to safely relight the pilot light.

 

If the flame keeps going out or won’t relight, it’s best for you to call a qualified Gas Safe registered heating engineer to inspect the boiler and identify the underlying problem.

 

Radiator balancing

 

Are some rooms in your home warm enough, while others far from your boiler are noticeably colder, even when the radiators are in full blast? That could mean that your radiators are unbalanced. If you ignore the problem, it can increase your energy bills. When certain rooms don’t warm up properly, you may turn the thermostat up to try to fix the problem. The result is that some rooms become too hot while others only just reach a comfortable temperature. Meanwhile, your boiler keeps running longer and working harder than it really needs to.

 

There are a few different reasons why this can happen.

·     Your heating system was never balanced properly when it was first installed or during a previous boiler service in your Wandsworth home.

·     Thermostatic radiator valves (TRVs) that don’t have auto-balancing features can also disrupt the flow of hot water through the system.

·     You may have removed your radiators while decorating or during repairs and then put them back. This can affect how the system distributes heat.

 

To fix the problem, it’s best for you to call us to balance your radiators. During your boiler repair in Wandsworth, we’ll adjust the radiator valves so that hot water moves evenly through the system. This should allow each radiator to heat up efficiently, roughly at the same speed.
