Gas Boiler (Repair & Servicing) in County Londonderry

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.

During a boiler service, your boiler engineer will perform a series of checks to ensure that your boiler is safe and efficient. First, they will conduct a visual inspection to check for any corrosion or leaks. They will also check the flame in your boiler. They’ll then remove the boiler casing and check all the components, including the heat exchanger, burner and spark probe, then clean the inside. After this, they’ll check the flue for obstructions and ensure that it’s safely fitted. They will then do a gas pressure check to ensure the boiler is working at the right pressure, before firing it up to check for any working faults.

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 Much Does A Boiler Repair Cost?

An annual service for your boiler might not seem important and may be easy to postpone to another day, but when it happens to breakdown due to lack of adequate attention, this can be quite painful and also costly.

Before you start thinking about the cost of repairing your boiler, the first thing you’ll need to confirm is whether or not your boiler is still covered by the manufacturer’s warranty. You’d be amazed some warranties can last for as long as 12 years, if yours is still on then you can save yourself a huge amount of of money on your boiler repair. As a result, it’s always crucial to keep the details of your warranty somewhere safe, so you can read them from time to time. You never can tell when the rainy day will come!

Most boiler warranties will require your to get your boiler serviced on an annual basis by a licensed and qualified technician. The cost of an annual boiler service is affected by the time of the year you wish to get it done. When boilers are less useful during the summer months, an annual service is usually relatively cheap when compared to the cold months. Around this period, a boiler service will normally cost within the range of £100 to £150, however for a more accurate quote it’s advisable to contact a couple of professionals and compare their quotes.

The cost of getting a boiler repaired will be affected by a couple of factors including your boiler’s make, the age of the boiler as well as your location and how urgent you need it done. If you have a dead boiler, the cost will typically range from £96 to £348 and a boiler displaying a fault code will cost within the range of £90 to £275. Generally, repairing a boiler will cost within the range of £90 to £400 based on the several factors stated above.
