What is a gas leak?

A gas leak is a very serious problem. It is not to be taken lightly as it can lead to dangerous health issues for your family. You will simply be able to smell the gas when it’s leaking. Natural gas has a smell added to it to make it easier to detect. When there is an issue preventing your boiler from burning fuel for completion, carbon monoxide can be produced and released. Without a doubt, it’s a lethal gas and can cause many health problems. Carbon monoxide has no smell added to it. It is also colourless. In order to detect a carbon monoxide leak, an alarm system should be placed near your system.

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

What is one off boiler repair?

A single boiler repair is necessary when your boiler experiences a fault that isn’t deemed an emergency. We provide one-off boiler repair services in Barry and the neighboring areas. The cost of a one-off boiler repair may fluctuate, influenced by factors like the duration of the repair, the complexity of the issue, and any unexpected 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 leaking boiler or central heating system poses a significant issue, regardless of the leak’s size. It’s crucial to immediately shut off both your water supply and boiler upon noticing a leak to prevent further damage. Typically, a faulty component is the culprit behind a boiler leak, necessitating repair by a Gas Safe registered engineer. Common sources of leaks include a malfunctioning pressure valve or pump seal, which may require replacement due to wear and tear. Additionally, pipe corrosion or improper installation can contribute to system leaks. Excessive boiler pressure is another potential cause, so when adjusting water pressure, ensure it remains within the manufacturer’s specified limits.

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

If you have an older boiler, it’s essential to check if the pilot light is illuminated. The presence of a pilot light indicates the operational status of your boiler. This small flame ignites a larger flame when hot water or heating is required, ensuring continuous functionality. Without a functioning pilot light, you may experience a lack of hot water and heating.

Cold radiators

A frequent issue encountered with radiators is the presence of cold patches, which fortunately can be easily resolved. When you activate your central heating, hot water circulates throughout the radiators. However, a buildup of air in the system can occasionally obstruct proper circulation, resulting in certain areas of the radiators remaining cold. To restore full heat distribution, it’s necessary to release the trapped air from the system. This procedure, known as bleeding, allows water to flow freely through the entire radiator, eliminating cold spots.

Hot water but no heating

Several minor issues could lead to a lack of heating in your home. Start by checking your thermostat, as it may require adjustment. Additionally, ensure to inspect the pressure of your boiler, as a drop in pressure can lead to central heating system failure. If both the thermostat and boiler pressure are functioning properly, it’s advisable to contact a gas engineer. There’s a possibility that a component within your boiler has malfunctioned or broken. For instance, if domestic hot water is functioning but heating is not, a faulty diaphragm, motorized valve, or airlock could be to blame. In the case of combi boilers, a stuck diverter valve may result in available hot water but no heating, as it directs hot water either to the hot water outlets or the central heating system.

Low boiler pressure

A boiler’s optimal operation relies on maintaining sufficient and required pressure. Insufficient pressure can lead to a loss of central heating and hot water. Over time, water pressure naturally decreases.

However, a sudden pressure drop could indicate a water leak. If a leak is suspected, both the boiler and water supply should be promptly shut off, and a heating engineer contacted for inspection and repair.

To assess boiler pressure, refer to the pressure gauge located on the front of the unit. If the dial reads below 1 bar, low boiler pressure is likely the issue. Consult the manufacturer’s instructions for the recommended pressure level, though typically boiler pressure should be around 1.5 bar.

How much does boiler repair cost?

Diverter valve      £150 – £35

Pump                     £100 – £30

Flue                        £15

Motorised valve £30

How to avoid costly boiler repairs?

To prevent costly boiler repairs, consider scheduling an annual boiler service.

Regular maintenance not only helps save money on expensive repairs but also ensures your boiler operates smoothly and efficiently. Over time, boilers naturally experience a decline in performance and efficiency.

However, with consistent servicing, this aging process can be delayed, extending the lifespan of your boiler for years. While most boilers come with a standard 5-year warranty, certain brands offer longer warranty periods.

To maintain the validity of your boiler warranty, regular servicing is essential. Essentially, your warranty remains valid as long as your boiler receives regular servicing.

Should I repair or replace my boiler?

If you find yourself frequently calling a gas engineer for repairs, it could be a clear indicator that you need to consider replacing your boiler.

Investing in a new boiler may prove to be a more cost-effective solution in the long term compared to continuously paying for repairs. Typically, the lifespan of a boiler ranges from 10 to 15 years.

It’s advisable to replace a boiler that’s reached 15 years old, but waiting until then isn’t always necessary. If your boiler is causing issues, particularly if it’s over 8 years old, it might be time for a replacement. Upgrading your boiler offers several advantages. Newer models are more energy-efficient, potentially leading to savings on high energy bills. As boilers age, their efficiency declines, resulting in increased energy wastage and higher bills. Therefore, replacing an older boiler can help mitigate these inefficiencies.
