Gas Boiler (Repair & Servicing) in Thornton Heath

Seeking a combi boiler repair or service in Thornton Heath? Our engineers in Thornton Heath will be able to give you the ideal quotes for having a central heating boiler repair or service completed.

Central heating boilers are amongst the most crucial parts of any household, providing heat and hot water all year long. Therefore any issues really need to be handled ahead of becoming a significant issue.

In the middle of winter it could cost a minimum of £200 just in call-out costs for an engineer. This is ahead of the cost of replacing parts.

To protect yourself from having to pay a lot of money, be sure to have your boiler serviced yearly so any issues can be found at the earliest opportunity. Moreover, having a service will make sure your central heating boiler is operating efficiently, lowering your charges.

The service may also highlight any threat too, such as a carbon monoxide leak. Carbon monoxide poisoning is responsible for hundreds of deaths and hospitalisations every year, so make sure this doesn't happen to you.

FAQs

How to repair a boiler leak?

If your boiler is leaking, there are some checks that you can do yourself. However, you should never attempt to repair your boiler yourself – only a Gas Safe-registered engineer should conduct repairs.

There are 3 main reasons why your boiler might be leaking: there’s a pressure valve fault, a temperature valve leak or corrosion in the system. An engineer will be able to spot the problem quickly, but in the meantime there are a few things you can do:

Check the pipe fittings

If your boiler is leaking water around the pipe fittings, it could be an installation fault and you should get in touch with the engineer that fitted it. You can check the pipe fittings by drying the area then waiting to see if the water appears again. If it does, you may be able to do a ¼ turn of the pipe to stop it. However, you should still call the engineer that installed it to ask them to check the PTFE tape on the inside.

Inspect the seals

Over time, the rubber seals on a boiler can start to perish, so if you have an old boiler this could be the source of your leak. If you have a new boiler, it could be caused by your boiler running over pressure.

Heat exchanger corrosion

Unfortunately, if a boiler engineer discovers that the boiler is leaking water from the heat exchanger, this is the end of the road for your system. The heat exchanger is the most expensive part of your boiler, so it makes more financial sense to replace your boiler with a newer, more efficient model rather than try to replace it.

Can I repair my own boiler?

No. You must never repair your own boiler – only a Gas Safe-registered engineer can do any work on your boiler. You can do simple DIY tasks to repressurise your boiler or stop a leak, but if you have to remove the outer casing of the boiler or touch the flue then you must get a qualified boiler engineer to take a look at your central heating system.

How often should I have a boiler service?

You should have your boiler serviced every year. This ensures that your central heating system is running safely and efficiently, but it’s often also a requirement to keep your boiler’s warranty valid. To avoid disruption to your heating, the best time of year to service your boiler is the summer. You’ll often find that boiler companies will charge less because they have less work.

how long does a boiler service take?

How Long Does A Boiler Service Take?

Servicing of your boiler is a very crucial activity which does not only help in keeping your heating system in a top condition, but also assists in ensuring the safety of both you and your loved ones. If you carry out a regular boiler service you’ll be able to identify any possible fault your boiler may have on time before it leads to a more serious issue or even a boiler breakdown. As a result, you’ll be able to save yourself some time and money, but more importantly will save you from any dangerous risk that may result from gas leak in a boiler. The best time for a boiler service is in the summer when you’d probably would not really need the system, so you can take advantage of that as well as the possible lower boiler servicing cost during this period.

Before we look into the amount of time a boiler service should take, let’s first consider what should be done during a boiler service.

✓ Visual inspection. This is a check carried out by the heating engineer to ensure your boiler still meet the existing standards and requirements while also looking for any faults.

✓ Removal of boiler casing. There’s the need to ensure everything is working just fine and also to clean the boiler’s interior. These inspections should include the burner, heat exchanger, main injector and spark probe.

✓ Flue check. This involves making sure that there’s no form of obstructions in the flue terminals as also to ensure that the flue is well installed.

✓ Gas pressure check. This involves making sure that the boiler working with the appropriate pressure.

✓ Boiler fired up. This involves checking for any operating issues.

Generally, a boiler service should be completed within 30 minutes, however this time may vary largely depending on the brand and model.
