Heating Engineer FAQs

how to fix a boiler?

How To Fix A Boiler

A boiler is subjected to regular usage, working for a several hours a day and providing hot water for shower on a daily basis and even more so during winter. With it’s power and efficiency, we tend to postpone or even totally overlook its maintenance. However, no matter how good your boiler is, it consists of many moving components and it’ll certainly develop some faults some day. When the inevitable occurs, you might want to save some money and get it fixed all by yourself.

When it comes to fixing boilers, seeking help from a licensed heating engineer is usually the best solution, however at times you might be just lucky to be faced with minor issues which you should be able to handle yourself. In this article, we’ll look at some of the most common causes of a broken boiler and how you can get your heating system up and running again. Let’s have a look!

✓ Low system pressure. In the event whereby your boiler display a low system pressure, it could mean that the system is about to breakdown. You’ll have to carry out regular inspections on the pressure gauge to see if there’s any noticeable changes and call in a heating engineer immediately to prevent a system breakdown from happening.

✓ Poor heat production. Although this is unlikely to lead to any great issues, but it’ll reduce the effective functioning of your heating system. To prevent a debris build, it’s important to have your boiler cleaned regularly.

✓ Strange noises. Boilers often make noises, so there’s nothing to worry about unless it’s a banging or whistling noise that’s very odd , then there may be a serious issue. You’ll have to check the air intake, pressure, exhaust and piping to ensure they’re working just fine, if not there may be a need for replacement.

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.

What’s LPG?

LPG stands for liquid petroleum gas. It’s a by-product of refined crude oil. When it’s put under pressure, LPG turns into a liquid. It’s usually stored in this form. LPG is used as fuel for things like BBQs and camping stoves, as well as central heating.

do i need a new commercial boiler?

Ad hoc visits from your engineer to fix small issues with your heating system may actually seem cheaper and a lot more affordable, however when a boiler is ripe enough for a change these small issues are always never ending. Over some period of time, these small issues will inevitably get worse and the idea of “mend and make do will be an absolutely false economy. The best course of action in this sort of event is to find a replacement boiler to install as soon as possible. In this article, we’re going to give you some hints that’ll show you when your boiler needs to be replaced. Now let’s take a look!

✓ Insufficient hot water. Here, you’ll have to check the size of your hot water cylinder. It’s crucial to make sure that your boiler is rightly sized to power your heating as well as hot water circuit in line with your demands. You should always seek the advice of a heating expert who can recommend whether to fix or replace the boiler.

✓ Strange noises. It’s normal for components of the boiler to become worn or damaged over time. Replacing the particular component that’s causing the knocking or rattling may seem cost effective at first but more often than not, the noises usually signal a bigger issue which is likely to build up over time. Hence, it’ll be a lot more logical to replace the boiler itself.

✓ Regular repair of your boiler. It’s essential to have your heating system serviced by a Gas Safe engineer on an annual basis. However, when you have to call them more often than once a year for your yearly maintenance, it may be a wise decision to consider getting a replacement.

✓ Other events whereby you may need a new boiler includes when you can’t get the right temperature in your room, when the radiators don’t heat up as they should, when your boiler leaks and if your boiler still has a pilot light.

what does british gas boiler cover include?

As you would have guessed, the British Gas is one of the leading home assistant companies located in the United Kingdom which delivers a large variety of services to customers and boilers. Basically, they offer four (4) service packages. The first package is an annual boiler service and boiler as well as controls repair. Meanwhile the fourth package (also the largest) combines boiler services with central heating, plumbing, drains as well as home electrics.

Apart from the monthly payment package offerings, customers are allowed to pay on a yearly basis with a large lump sum. If you opt to pay annually, this will help you save some amount of money. There’s also the option of paying an extra £60 to further lower either monthly or annual costs. What’s more? Customers are also allowed to pay an extra of £99 to get either £2.50 for boiler repairs a month or £5.50 for both repairs on boiler and its controls as well as central heating system repairs.

After placing a claim, the repairs required by your boiler would be made within 24 hours. However, in certain cases, there may be some delays as British Gas tend to rate vulnerable customers ( such as elderly persons and families with little kids) higher than the usual ones. All products will include a 24/7 customer support, unlimited call outs as well as a 14 day cooling off period if you choose to remove any service.

In conclusion, British Gas is an affordable and hassle free company offering customers top notch services. Their gas boiler cover include so many juicy benefits you simply can’t afford to miss out on if you have a gas boiler in your home or property.

Why should I get an oil fired boiler?

If your property is not connected to a gas main, oil boilers are a great alternative to gas boilers and more efficient than LPG alternatives. They can also be paired well with renewable sources. However, if your property is connected to the gas mains, there is generally no reason to switch to an oil boiler, as you will need to have oil delivered to an extra storage tank.

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.
