how to fix a broken boiler?

How To Fix A Broken Boiler

To fix any problem when it comes to home appliances, the first step is always to identify the problem while also carrying out thorough checks - a broken boiler is not an exception. Putting enough time and effort in diagnosing a problem can go a lot way to save you both time and money. So here are some of the steps you can take to fix your broken boiler before you put a call out to a licensed engineer.

✓ Check to confirm if your pilot light is on. Whenever you’re facing some issues with your boiler, this should always be the first thing you do. The pilot light being on speak volumes, if the light is off then there’s absolutely no way the flame can start the appliance’s gas supply. You should try to put it back on, if off. To do this, you simply have to follow the detailed instructions on your boiler’s manual strictly. If after following these actions to the letter and the issue remains the same, then you’d probably need the services of an a qualified engineer. Never try to fix the issue on your own.

✓ Check the pressure. The solution to the headaches might sometimes be as simple as examining your appliance’s pressure gauge. Here, the good numbers are around 1.0 or1.5, if it happens to fall below this, then you should open the boiler’s instruction manual. You can also inspect your radiator valves for any leaks. You’d have to call in a specialist to solve the issue.

✓ Check the thermostat. Here, it’s important to note that a faulty thermostat doesn’t necessarily imply a broken boiler. It may just signify that you need to replace your thermostat. Simply check to ensure that your thermostat is turned on and temperature is at the appropriate degree.

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 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.

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.
