Heating Engineer 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.

how often should you service an oil boiler?

How Often Should You Service An Oil Boiler?

If you have an oil boiler, you probably know the importance of having it serviced to ensure its proper functioning, prolong its useful life as well as ensuring the safety of your home. However, the question that most frequently arises is how often would one need to service the prized hating system? If you’re also looking for the answer to this same question, then you’ve come to the right place. To make sure your oil boiler is running smoothly, safely and efficiently, it should be serviced as often as once in a year. You certainly do want to know the numerous disadvantages of failing to service your boiler. Not only will neglecting your oil boiler service result in possible faults as well as higher energy bill caused by its inefficiency, but can also lead to your warranty ending early.

Therefore, you should ensure your oil boiler is serviced by a qualified heating engineer on an annual basis to make sure it’s running just as it should. This will give you peace of mind knowing you wouldn’t be spending huge bucks on possible repairs and in some cases, replacements.

As a landlord in the UK, it’s a legal requirement to make sure that your oil boiler and flue system is services on a yearly basis in your rental property.

Unlike a gas and oil boiler, an electric boiler do not require the same level of maintenance or servicing. However, it’ll be a nice move to ensure that it’s also checked once in a while.

Overall, it’s important to note that failure to service your oil boiler on a yearly basis can give rise to multiple risks. These includes a rise in energy bills, carbon monoxide leak, fault that can cause boiler breakdown as well as an expensive repair or replacement bill.

does home insurance cover boiler?

Breakdowns of boilers are quite common during the winter months and are usually very expensive to repair when this occurs. According to the research carried out recently by uSwitch, repairing a boiler can cost an average of about £314 with a figure over 20 percent of homes experiencing various heating system issues last year.

To answer the question of whether or not your existing home insurance will be enough to cover the boiler breakdown, the answer is probably not. This is due to the fact that heating system faults or breakdowns is a very common occurrence and as a result of poor maintenance practices as well as a high repair cost, several insurance companies often remove it from their home insurance policies.

Generally, you’d be given an option of what is termed as “emergency home cover which is an add on or extra to your home insurance policy. Luckily, this add on is quite inexpensive and may be as little as £4 or £5 per month. Depending on your need or budget, you can also purchase the add on as a “stand alone from your current insurer or another company. However, the stand alone option is usually more expensive.

The emergency home cover normally provides coverage for the boiler repair cost and few times, the rest of the central heating system as well. Being fully aware how important a boiler can be, insurance companies usually deliver a rapid response service as suggested in the name, “emergency home cover. However, the maximum pay out for call out charges is capped at a particular amount which usually ranges from £500 and £1,000. Apart from the call out fees, the emergency cover also includes a limit on the pay out amount for future required repairs of heating systems which includes both parts labour.

how long does a gas boiler last?

When it comes to gas boilers, this is one of the most frequent questions that always pops up and for a good reason. When you invest a considerable amount of money to acquire and install a gas boiler in your home or property, it’s only reasonable not only to expect the boiler to warm up your home efficiently, but also to do so for a long period of time. If you’ve just bought or about to get a new gas boiler, it’s likely you won’t have to worry about getting a replacement for a lengthy period of time. Several gas boilers will last for anywhere between 10 to 15 years on the average. However in the event whereby you have an existing one that’s fast approaching the end of it’s useful life, then you should know the time go get a new gas boiler is just around the corner, and the earlier you make the purchase, the better (to avoid any surprise breakdowns that’ll leave your home super uncomfortable).

Just like any other home appliance, it’s a fact that an older gas boiler ( especially those that have been installed over a decade ago) are significantly less efficient that the new modern ones. When the older versions were manufactured is a completely different time to now as both technology and climate concerns are wide apart. So when your existing boiler is approaching the end of it’s useful life, it’ll be wise to start saving up to cover the cost of getting a new one. However, if it’s only about 5 years ago your boiler was installed, it’s highly likely to still be very efficient.

should i get boiler cover?

A terrible day would be walking into your home to discover your boiler is broken - nobody prays for that and even more so, when you’re fully aware a broken boiler can be one of the most expensive things to repair. However, when this occurs, a boiler plan is ready to help cover the repair cost - and that’s only if you’ve gotten one. Generally, cover plans feature only a monthly price which is quite affordable when compared to paying a huge lump sum at once. Furthermore, depending on your cover level, you may not be required to incur call out charges or any other expensive services rendered. And in the event whereby your boiler can’t be repaired, there’ll be plans in place to get a replacement unit. As a result, getting a boiler cover is a great way to give yourself a peace of mind and see to it that you’re not left in the cold when the worse happens.

So the answer to whether or not you should get a boiler cover is totally a positive one. The purchase of a new heating system can be quite costly, but it would even be costlier when you have to repair it ceaselessly throughout it’s service years. With several modern combi units being a complicated heating system to repair, getting a cover plan with unlimited call outs, zero excess as well as cover parts and labour would be a truly wise decision.

In addition, an annual service of your heating system is required by manufacturers in order to make the warranty valid. Therefore, just a basic service plan is very crucial if you do not buy the idea of having to fork out at least £70 for each service.

What Size Of Electric Boiler Do I Need?

If you’re thinking about installing central heating in your home or property, you’ll be shocked by the plethora of options that’s currently available in the market as regards the boiler type that can be installed.
