As the seasons change and the weather gets colder, we rely more on our boiler systems to deliver warmth and hot water to our homes. It goes without saying that a boiler is a crucial system in the home, one that needs to be in optimal condition at all times.
But like any other appliance, boiler system parts wear out and can get faulty, especially when it’s been pushed to their limits or it malfunctions. To prevent complete a breakdown, you’ll need to maintain and repair your boiler system throughout its lifecycle. This includes getting it serviced at least once a year by a qualified gas safe engineer.
Are you having problems with your boiler and would like to know what’s wrong? Over the years, we have repaired many boiler systems in or around Gloucestershire, and also carried out some emergency boiler service jobs and gas central heating repairs. We know the most common types of issues you can expect. Our out of hours gas engineers have seen their fair share of breakdowns.
Boiler problems can be a real pain, particularly in the winter when the temperatures can drop below zero. These issues range from leaks to cold radiators and others. If you detect any of these issues, you can contact us for an one off boiler repair.
Top 5 Most Common Boiler Problems
Boilers are expensive systems and are built to last for years. But faults, such as boiler leaks, are one of the most common boiler issues fixed by gas leak engineers. They are routine fixes that can be completed within the hour in most cases, if parts are available, or parts would need to be ordered in from the merchants. Water leaks can cause damage to the internal components of a boiler and the surrounding appliances, so they should be a priority to fix. Not to mention it may render the boiler unusable.
There are several causes of a leak which usually indicate its cause. They include:
● Excessive boiler pressure
● Corroded pipes
● A faulty part
● Seal Leaks
● Faulty installation from the onset
You can contact us on the number on this page if you have any of the above issues. And we’ll send out an emergency gas safe engineer.
No Hot Water/Heat:
A boiler system is designed to provide the home with heat and hot water. When it fails to do one or the other, you should call an expert to investigate the root cause.
If you’re using a combi boiler system and you have hot water but no heating, go through the boiler settings and set its performance to central heating and hot water (so have both options switched on). If that is not the issue, then the radiators might need bleeding (could be trapped air). If you’ve confirmed the setting (and tried bleeding) but it’s still faulty, there might be something wrong internally. And the best thing to do is contact us and an emergency gas boiler engineer can investigate.
If you have neither hot water and heating, then several factors could be the culprit such as;
● Problems with pipes, such as an airlock
● Boiler pressure too high or very low
● A fault within the system
Low Boiler Pressure:
Boiler pressure is the speed at which hot water passes through the central heating system. When the boiler’s pressure is too low, the central heating will fail to work correctly, resulting in a lack of hot water.
Every boiler system has an analog or digital pressure display panel that shows the level of water pressure in the system. Ideally, you don’t want anything below one because the pressure will be too low. Instead, you should set the water pressure at 1.5 or thereabouts, depending on the boiler brand.
Over time, all boilers lose pressure due to wear and tear after continued use. However, a sharp decline in pressure is an indicator that something else is causing the decline in pressure. If you notice this, check for leaks and cold patches on your radiators.
There are three main reasons why a boiler experiences low pressure:
● A leak in the system that reduces the amount of water in the system
● Bleeding a radiator
● A failed part
If a part has failed, you can always give us a call and we’ll send out an emergency central heating engineer/24 hour central heating engineer.
A heating system sometimes makes noises that range from banging and clanging to whistles and gurgles. When your boiler starts to make a strange noise, you should have it looked at immediately.
Noises usually indicate something is wrong with the system. Here are some causes:
– A build-up of sludge
– Trapped air
– A faulty pump
– Blocked air filters
A 24 hour boiler engineer will be able to assist you.
Boiler kettling is what happens when water is heated quickly until it boils, causing steam to rise quickly and air becomes trapped. When this happens, the boiler whistles like a kettle with boiling water.
Kettlings root cause is limescale build-up, and this slows down the flow of water in the system, causing water to boil faster than it should. Sometimes, a faulty component or a defect in the system causes the boiler to heat up water excessively.
Boiler Kettling can be fixed by cleaning out the pipes; however, other more severe cases may require other cleaning methods or part replacement. A 24 hour gas safe engineer can carry out a full investigate and eliminate the problem.
Modern boilers are much more reliable and tend to have fewer issues when compared with older units. They are also covered by a warranty period which gives users a greater sense of security and confidence. A warranty will see to it that you are compensated by the manufacturer in the event of a fault (their terms and conditions will apply and never tamper with a boiler on your own).
As with the vast majority of boiler repairs, maintainable checks and repairs should be carried out by a registered professional. A call out gas engineer can help.
