FAQs

can i repair my own gas boiler?

Can I Repair My Own Gas Boiler?

If you’re more of an handy person, then you’d probably want to fix everything you can around the house while saving yourself some money that would have been spent on hiring a professional instead. This is a very cost effective but at the same time you must know that some tasks are usually more difficult than others, and a good example of those complex tasks is boiler repair. Not only can this be very tough, but they can also potentially be one of the most dangerous home appliances you can acquire. So with that in mind, what can be done to ensure your gas boiler is taken care of and in the event whereby it starts to malfunction, what can be done to remedy the situation?

With regular maintenance and repair of your gas boiler, you’d have absolutely nothing to worry about. However one of the fear several DIYers have is the fact that they might just end up incurring more expenses on services they didn’t really need in the first place. But when it comes to gas boilers, it’s necessary to be certified to work with them as it’s very dangerous to tackle it all by yourself. Despite this, there are still some minor issues that you wouldn’t need to hire a technician to resolve. In some cases, all that would be needed is simply to reset the boiler. To identify where the reset button is, simply go through your boiler’s manual for more information. Most times, all you’ll have to do is press down the reset button for a couple of seconds. If the boiler isn’t fully restored to its normal proper functioning state after two resets, then you may need to call in a professional for help.

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 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.

how often to service boiler?

How Often To Service Boiler?

A boiler is a vital part of any home especially if you’re in the UK. Not only does provide your entire household with hot water and keep them warm but also adds a good value to your property. Boiler repairs and replacement are both super expensive and stressful, so in order to avoid all these worries, it’s better to have your boiler serviced on a regular basis for your own peace of mind. When you call in a reliable heating engineer, it can immensely raise your boiler’s efficiency while also saving you from more expensive issues down the road.

So if you haven’t had your boiler serviced for quite some time, moved into a new house and not aware the last time your boiler was serviced or perhaps you’re just wondering how often a boiler should be serviced, then you’ve come to the right place! The short and simple answer to this question is a boiler should should be serviced once in a year, and most preferably during the summer months. However, there are a wide range of factors that comes into play so it’s always advisable to check with your manufacturer before you proceed.

According to the law, you’re required to have your boiler services on an annual basis. Failure to do so can render your boiler or home warranty void. Therefore, it’s very crucial to take down the last time your boiler was serviced and also set a reminder to book your next appointment when the time closes in.

If you happen to own an electric boiler you may not need an annual servicing. But you may still be required to perform it annually by your insurance provider.
