Emergency Central Heating Repairs and service Cardiff 

There are various potential issues that can arise with your boiler. It’s crucial to differentiate between emergency repairs and one-time fixes. Here’s a breakdown of what constitutes an emergency:

● A gas leak

We respond to an emergency repair situation in Cardiff within 24 and will try our best to be at your doorstep as soon as possible.

What is a gas leak?

A gas leak poses a significant hazard that should not be underestimated, as it can pose serious health risks to your family. Gas leaks are typically detectable by their distinctive odor, as natural gas is intentionally odorized

for easier detection. However, when a boiler malfunctions and fails to combust fuel properly, it can produce and release carbon monoxide, a colorless and odorless gas that is extremely dangerous. Carbon monoxide is lethal and can cause a range of health issues.

Unlike natural gas, carbon monoxide does not have an added odor. Additionally, it is invisible. To detect a carbon monoxide leak, it is essential to install an alarm system near your boiler.

What are the symptoms of carbon monoxide poisoning?

● Dizziness

● Headaches

● Nausea

● Breathlessness

● Collapsing

● Unconsciousness

What to do in the event of gas leak

● Firstly, open all windows and doors

● Do not press any switches or light any flames whatsoever

● Evacuate and leave the property

● You can call the Gas Emergency Service

What is one off boiler repair?

A non-emergency boiler repair refers to a situation where your boiler has a fault that does not qualify as an emergency. We provide one-time boiler repair services in Cardiff and the neighboring areas.

The pricing for a one-time boiler repair may fluctuate based on various factors, including the duration of the repair, the complexity of the issue, and any unforeseen complications that may arise.

What are some of the most common boiler repairs?

Some repairs are more common than others due the frequency at which they happen. It is always advisable that you hire a professional gas engineer to carry out these repairs to be on the safe side even when you think it is a minor repair.

Boiler leaking

A leak in your boiler or central heating system, regardless of its size, poses a significant concern. It’s advisable to shut off both your water supply and boiler immediately upon noticing any leakage to prevent exacerbating the issue.

A malfunctioning component typically triggers a boiler leak, underscoring the necessity of having a Gas Safe registered engineer handle the repair. The culprit behind the leak is often either a faulty pressure valve or a worn-out pump seal, both of which may require replacement. Additionally, pipe corrosion or improper installation can contribute to system leaks.

Excessive boiler pressure is another potential cause of leaks. When adjusting your boiler’s water pressure, it’s essential to ensure that you adhere to the manufacturer’s specified limits to avoid inadvertently causing leaks.

No hot water or heating

We know how annoying and upsetting it is to be left without hot water in the midst of winter. Several factors and reasons can cause this problem. To name a few:

● Power to the boiler is off

● Gas is not being supplied to your property or that the oil storage tank is empty

● Boiler pressure is too low.

● The condensate pipe may be frozen due to freezing weather conditions

Check the pilot light on your boiler to see if it is on or not if you have an old boiler. Without a pilot light, you will be left without hot water and heating. A pilot light is an indication of the status of your boiler. It lights a larger flame when there is a need for hot water or heating.

Cold radiators

Encountering cold patches on radiators is a frequent issue, but fortunately, it’s relatively simple to resolve. When you activate your central heating, hot water is circulated throughout the radiators. However, if air

accumulates within the system, it can occasionally obstruct the flow of hot water, leading to incomplete heating of certain radiators and the appearance of cold patches.

To restore proper water circulation and eliminate cold spots on the radiators, it’s necessary to purge the air from the system. This procedure, commonly referred to as bleeding, involves releasing trapped air from the radiators.

Hot water but no heating

Several minor issues could be the culprit for a lack of heating in your home. Begin troubleshooting by checking your thermostat, as it may require adjustment. Additionally, inspect the pressure gauge on your boiler, as a drop in pressure can lead to a malfunction in your central heating system.

If both the thermostat and boiler pressure appear to be functioning correctly, it’s advisable to contact a gas engineer. There may be a faulty or broken component within your boiler causing the issue. For instance, if your domestic hot water is working fine but your heating isn’t, a malfunctioning diaphragm, motorised valve, or airlock could be to blame.

In the case of combi boilers, they feature a diverter valve that directs hot water to either the taps or the central heating system. If this valve becomes stuck, you may have hot water available but no heating.

A boiler will not operate well without the sufficient and required pressure. As a result, you will be without central heating and hot water. Water pressure can naturally decrease over time. However, a sudden drop in pressure can be a sign of water leak. The boiler and the water supply should be shut off in case of water leak. A heating engineer should be contacted.

To check the boiler pressure, you can look at the pressure gauge on the front of the unit. The cause of the problem will be the low boiler pressure if the dial is anywhere below 1bar. Check the

instructions provided by the manufacturer to know the right pressure. However, boiler pressure is usually around 1.5bar.

Should I repair or replace my boiler?

If you find yourself calling a gas engineer regularly and more than usual, then it might be a clear sign that you might need a boiler replacement. Investment in a new boiler might save you more money in the long run than paying money for repairs on a regular basis.

The lifespan of a boiler is set to be around 10-15 years. It is advisable that a 15 years old boiler is bound to be replaced. That, however, does not mean that you should wait 15 years in order to replace your boiler. If your boiler is giving you troubles, then it might be time for you to replace it, especially if it is over 8 years old.

Replacing a boiler has several benefits. A new boiler is always more efficient than an old one and it can save you money on high energy bills. When an old boiler drops in efficiency, it can waste more energy and as a result, you can get higher energy bills.

How often should central heating be serviced?

It’s recommended to have your central heating system serviced at least once annually. Regular servicing plays a crucial role in ensuring the efficient and safe operation of your central heating system. It enables early detection and resolution of any potential issues, thus helping to prevent costly repairs and prolonging the lifespan of your system.

During an annual service, a qualified heating engineer conducts a comprehensive inspection and maintenance of various components such as the boiler, radiators, pipes, controls, and ventilation systems. They clean, test, and fine-tune the system to optimize its performance while also checking for leaks, blockages, or signs of wear and tear.

By adhering to a regular servicing schedule, you can nip minor problems in the bud before they escalate into major breakdowns, enhance energy efficiency, and ensure that your central heating system continues to deliver reliable warmth and comfort for years to come.
