Signs You Need Boiler Repairs in Glasgow

What Are the Common Signs That Your Boiler Needs Repairs in Glasgow?

At the Glasgow Boiler Company, we know just how frustrating and inconvenient a broken boiler can be. The last thing any Glaswegian wants is to be left without heat and hot water. That’s why it’s so important to be able to recognise the signs that your boiler needs repairs before it breaks down completely and that you need emergency boiler repairs from a gas-safe engineer.

We’ve been providing top-notch boiler repair services to homeowners and businesses throughout Glasgow for years. In that time, we’ve seen just about every boiler issue in the book. Having that experience under our belts allows us to quickly identify boiler problems and get them fixed fast by our qualified technicians.

Today, we’re sharing some of the most common signs of a faulty boiler that indicate you likely need a professional boiler repair. Spotting these red flags early can help you prevent further damage and avoid a full system failure that may require a boiler replacement. Let’s dive in!

At the Glasgow Boiler Company, we’ve seen a rising trend of homeowners in Glasgow transitioning away from traditional heating systems and towards eco-friendly air source heat pump technology. As a company committed to providing sustainable heating solutions, we couldn’t be more thrilled about this shift.
In this blog post, we’ll explore the driving forces behind heat pumps’ growing popularity in Glasgow and why we believe they represent the future of efficient heating.

Boiler Repair

Unusual Noises Coming From the Boiler

One of the clearest signs that something is amiss with your home’s heating system is if you start hearing odd or unusual noises that you’ve never noticed before coming from the boiler unit. During normal operation, boilers shouldn’t make loud, persistent clanking, banging, whistling, gurgling sounds or other strange noises.

While a few minor sounds here and there may not necessarily mean there’s a serious underlying issue, any recurring or worsening noises indicate it’s time to have one of our gas-safe engineers take a look. Odd boiler noises can be caused by a number of potential problems like:

  • Kettling from limescale buildup
  • Mechanical faults with the pump or motor
  • Air in the system pipes
  • Loose components rattling around

The earlier these types of issues are resolved through professional boiler repairs, the better. Ignoring loud boiler noises will only lead to worsening damage and more costly boiler repair down the line, which could require a new boiler installation.

Leaks or Moisture Around the Unit

Another major red flag that should never be ignored is any sign of leakage or excess moisture around your boiler unit. Whether it’s a slowly dripping leak, visible leaks, or a larger pool of water, get it checked out as soon as possible by one of our gas-safe registered engineers.

There are a few different things that could potentially be causing the leak:

  • A broken boiler component like the pump, valves or broken diaphragm allows water to escape
  • Corrosion, cracks or other damage in the boiler tank or pipes
  • Improper installation leads to loose pipe fittings

No matter the root cause, leaks from a gas or oil boiler need to be fixed quickly to avoid further damage. Water leaking can damage floors, walls, or surrounding areas and increase the risk of dangerous carbon monoxide or gas leaks.

If you notice any signs of moisture, shut off your boiler right away and give our team a call for an emergency boiler repair visit from a gas safe registered engineer.

Pilot Light or Ignition System Failure

For gas boilers with a pilot light rather than an electronic ignition, a failure to stay lit is a definite cause for concern that needs prompt boiler repairs. While a draft or another minor issue could potentially be to blame for the pilot going out occasionally, anything beyond an occasional relighting likely warrants professional inspection from a heating engineer.

With electronic ignition systems, you’ll want to watch for symptoms like:

  • Delayed firing or ignition when starting the boiler
  • Complete failure to ignite or fire up at all
  • The ignition system switched on and off repeatedly

Ignition troubles can stem from various potential sources like a bad igniter, faulty thermostat, safety switch problems, or even issues with the gas supply itself. Our experienced engineers can quickly diagnose the root problem and make the necessary boiler repairs.

Minimal or No Heat From Radiators

When your boiler is functioning properly, it keeps your radiators toasty hot and your home nice and warm, even during a Scottish winter. If the radiators suddenly go cold or only put out very minimal heat, it’s a sure sign that you likely need a boiler repair from a qualified heating engineer.

There could be numerous boiler-related culprits here:

  • Low water pressure or loss of pressure in the system
  • Airlock or debris buildup in the pipes restricting water flow
  • Valve, pump or thermostat failure preventing water circulation
  • Diverter valve or thermostat issues

While poor radiator heating may sometimes originate from plumbing problems too, the boiler itself is usually to blame if it needs bled or serviced. Our heating engineers know to check the entire system during our thorough inspections.

Higher Than Normal Energy Bills

Have your energy bills been creeping up lately despite no big increase in usage? Unexpectedly high heating costs could indicate that your boiler’s efficiency has taken a nosedive, and it now has to work harder to provide the same level of heat to your home.

Modern, energy-efficient boilers operate quite economically when properly maintained through regular boiler maintenance and servicing. However, as they start to deteriorate over time, that efficiency level drops off, leading to increased energy bills. Scale buildup, ventilation problems, damaged boiler parts—all sorts of issues can lead to higher energy consumption.

If your heating bills seem out of line compared to previous years, that’s a reliable sign that your system’s performance and condition have declined. Don’t just chalk it up to rate hikes! Get your boiler looked at by one of our registered gas-safe engineers to find the root cause and get it back into peak operating condition through a boiler repair or a newer, more efficient replacement.

Yellow or Flickering Pilot/Burner Flame

For gas boilers, you’ll want to monitor the pilot light or burner flame’s colour. A crisp, blue flame indicates proper fuel combustion and air supply. If you notice that the flame is burning yellow, flickering consistently, or seems overly sooty, don’t ignore it.

Off-colour or unstable flames typically mean that the fuel isn’t burning cleanly and completely. This could indicate:

  • Ventilation or flue issues allowing leaks or backdrafts
  • Problems with the gas valve or fuel supply
  • Issues with the combustion air supply

Any of these scenarios translates into an increased risk of dangerous carbon monoxide leaks, which require immediate attention and safety measures. At best, soot buildup just makes the boiler work inefficiently. At worst, you have a major safety hazard on your hands that needs to be resolved immediately by a gas-safe registered engineer.
