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.

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.

does home insurance cover boiler repairs?

Does Home Insurance Cover Boiler Repairs?

When winter comes, your boiler is most likely to be one of the most used appliances in your home. It keeps operating for several hours to ensure your house remains warm and conducive and then during those cold evenings, it supplies the much needed hot water to guarantee a restive night. But with so much usage and many moving parts, you’d naturally expect your boiler to breakdown at some point especially if it’s 7 years old or above. So what’s the next line of action when it happens, leaving your radiators off and water cold? With the likely high boiler repair cost, it’s only logical to consider whether your boiler repairs is covered by your home insurance.

In almost all situations, the standard home insurance will not provide coverage for the cost of repairing or replacing a broken boiler. Being fully aware that boiler breakdowns are mostly caused by a lack or not so regular maintenance practices or servicing, most home insurance providers will exclude it from this from their offerings. In fact, a home insurance is more likely to provide coverage for the damage that has happened as a result of a broken appliance. For instance, the damage caused as a result of gas, oil or water leaking from a boiler are more likely to be paid for by the home insurance providers, but they’ll not pay for the repair or replacement of the broken boiler itself.

If you need our home insurance to cover your boiler repair, then you might just be able to get an extra insurance cover from your provider that includes a broken boiler repair. You can consult them to determine if this is possible as well as the cost to be paid per month. This will normally cost about £5 to £10 per month, but it gives you a peace of mind knowing you’re covered if your boiler happens to breakdown.

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.
