5 Warning Signs Your Boiler Needs Expert Attention

Ticking. Gurgling. Hissing. Does your boiler sound more like a haunted house than a reliable heating source? Don’t dismiss these unusual noises. They could be warning signs of a bigger problem brewing beneath the surface – a problem that could leave you shivering in the cold and pose a serious threat to your safety. We’re talking about the silent killer: carbon monoxide poisoning.

This invisible, odourless gas can leak from a malfunctioning boiler, leading to headaches, dizziness, and even death. While a full-blown breakdown is rare, you don’t have to wait for the worst to happen. Recognising the early boiler warning signs can give you the power to act before things get critically cold (and dangerous).

How Do You Know if Your Boiler is Malfunctioning?

The dangers of faulty boiler can cause leaking carbon monoxide, a silent, deadly gas. We expose the top 5 clues that your heating system is harbouring hidden inefficiencies and potential safety hazards.

Your Boiler is Leaking

A common cause of boiler leaks is corrosion. The metal parts may get weak from being in contact with water, heat, and chemicals. This can make them break or crack and cause leaks. In this case, the gas engineer may need to replace some of the pipes and fittings to stop the leak.

Now, there could be other culprits, too. High water pressure, frozen pipes, a dodgy valve, or worn-out components can all result in a leaky boiler. These parts work hard to keep your boiler running, so some wear and tear is normal over time. The gas engineer will check if any faulty part needs to be replaced.

In the worst-case scenario, if a major defect is found within your boiler, a new one may be necessary. We know that sounds like a massive headache and a big hit to your wallet. But you can apply for a free boiler grant if you’re eligible. For instance, under the current scheme, your boiler must be over 7 years old. You also need to be a homeowner and receive certain benefits.

Your Boiler Pressure is Low

If your boiler pressure falls below 1 bar, it’s likely due to a recent radiator bleed, a leak somewhere in the system, or a faulty component. A quick fix to shooting the pressure back up is simply repressurising your boiler!

Once that’s done, you should focus on getting the boiler leak or damaged components fixed by a professional. Otherwise, the pressure may get low again. Keep in mind that it’s challenging for a low boiler pressure to keep your space consistently warm. You may also get high heating bills if you don’t address the root causes behind a pressure drop right away.

Another boiler warning sign is high pressure. There might be a blockage somewhere that’s preventing the pressure from regulating itself. Don’t try to be a DIY expert on this one and consult a Gas Register heat engineer.

Your Boiler is Leaking Carbon Monoxide

How to detect carbon monoxide? You can’t depend on your senses because this lethal gas has no colour or odour. Here are some signs to look for:

  • Orange or yellow boiler flames instead of blue
  • Soot or stains
  • Difficulty lighting fires
  • Unusual behaviour

If you suspect a carbon monoxide leak, take action right away. Open all the windows in your home to ventilate the potentially harmful gas. Then, switch off your boiler to put a stop to the source of the leak.

Next, contact a Gas Safe registered engineer to take a look at your boiler and make sure everything is in working order. If anything needs to be fixed or replaced, they’ll know just what to do. Do not attempt to fix the boiler yourself. It can be hazardous without proper knowledge and training.

In the unfortunate event that you or your family members have been exposed to carbon monoxide, seek medical attention immediately. Even if you start feeling better, always err on the side of caution and seek medical advice just to make sure everything is okay.

You could increase the safety of your home by installing a carbon monoxide detector. However, it should never take the place of regular maintenance and servicing. Think of it this way: while a carbon monoxide detector alerts you to exposure, proper upkeep ensures that no leaks even occur.

Most importantly, always have good airflow in the room with a fuel-burning machine and often check to make sure nothing is blocking or leaking from the chimneys and flues. Get your chimneys and flues cleaned regularly.

Your Boiler is Noisy

Banging, gurgling, grinding, whistling – these aren’t sounds you want to hear from your boiler. There are a few things that might be causing this. Air in the system can cause gurgling sounds, while a faulty pump may lead to grinding noises. If the water pressure is too low, your boiler might whistle. And if you live in an area with hard water, limescale build up could also be causing some noise.

You don’t need to know the dangers of a faulty boiler on your own. A registered gas engineer can identify and fix the problem for you.

Your Boiler isn’t Heating Properly

Your boiler might be overheating, and the culprit could be something as simple as a dusty air filter. Even a faulty thermostat can make the boiler too hot or not hot enough.

Other reasons for inefficient boiler heating could be a frozen condenser pipe, an unstable pilot light, or a malfunctioning ignition system. You need a registered gas engineer to figure out the main root cause and resolve it.

If your boiler is over ten years old, it might have lost some of its power and can’t keep up with your heating needs. Upgrading to a new one means you’ll be toasty warm all winter long.

Final Words

If you have a faulty boiler, get it checked by a registered gas engineer as soon as possible. Fixing problems quickly will keep your boiler functional for a long time. Ignoring an underperforming boiler could lead to more serious issues down the line. If your boiler is a decade old or older, consider an upgrade to avoid frequent repair costs and high bills.
