FAQs

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.

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.

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.

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.
