Is my central heating in need of a repair?

Published on February 28, 2023

You probably rarely ever think about your central heating system until things start to go wrong. You might start noticing that things aren’t working as well as they should, but unless your boiler breaks down, you might push it to the back of your mind. This is understandable but it can lead to bigger problems down the road, that can’t be ignored and may be costly to fix. 

The team at RJ Martindale have dealt with many different types of central heating repairs. We’ve used our knowledge and experience to provide guidance on different central heating issues and how best to solve them. Take a look at our article below to find out more. 

How to spot problems with your central heating

Your radiators have cold spots

When you notice that your radiators have cold spots, it may indicate that it’s time for a powerflush. This is when one of our expert Gas Safe Registered engineers flushes out your heating system, making sure to clean out any debris, sludge and rust that builds up over time. This will help your system work more efficiently and should get rid of any cold spots. 

Your radiators only heat at the bottom

This is quite common and usually indicates the need to bleed your radiators. This releases any trapped air inside. You can bleed your radiators yourself, using a radiator key, these can usually be found in DIY shops or you can order one from Amazon. 

Bleeding radiators is an important part of maintaining your home’s heating system. It allows water to move more freely, increasing efficiency and performance. This task can seem mundane and tedious, but it’s essential for keeping your home warm, especially during winter. 

Another benefit is that bleeding radiators can reduce the noise coming from them, as air bubbles can create loud sounds when they expand and contract against walls of metal piping found in most central heating systems. 

Your boiler is making a strange noise

There are many different reasons your boiler is making a strange noise, but they’re usually never good. It could be something simple like having the wrong pressure, you can check this by looking at the gauge on your boiler. It should be in the green zone, at around 1 – 1.5 bars. 

Sometimes it can indicate the need for a powerflush, but it can also be a warning for something more complex, where you’d need a professional plumber to come and check it out to identify the issue and ensure your safety.

Your pilot light has turned off

When your pilot light goes out, it means your boiler can’t heat water. There are a few reasons why this may happen, and one is to prevent a build-up of gas if there happens to be a leak. If your pilot light has turned off, please get in touch with a Gas Safe Registered engineer as soon as possible. Gas leaks are extremely dangerous and in some cases, fatal. 

Your radiators aren’t heating up at all

If your boiler is on and seems to be working as it usually does, yet there’s no heat from your radiators, there could be a problem with your thermostat. Thermostats are made up of delicate components that can wear out over time. It could be a small part or a wire, but either way, it will need to be checked by a professional. 

Fortunately, a faulty thermostat is easy to resolve and your plumber should be able to fix it or replace it quickly.
