Boiler Broken Down?

You don't need to face it alone

Whatever has happened with your boiler, there is a clear next step. Here is what to do if you are dealing with any of the following.

Loss of Heating

If your radiators have gone cold, check your thermostat and timer first. If the boiler still won't heat, get in touch and we will talk you through it.

No Hot Water

No hot water can point to a few different causes. Our team can talk through what you are experiencing and arrange a visit to diagnose it properly.

Boiler Shutdowns

A boiler that keeps shutting off is often protecting itself from a fault. Do not keep resetting it repeatedly, contact us and we will investigate the cause.

Fault Codes

An error code on your display is useful information for our engineers. Have the code ready when you contact us so we can advise on next steps.

Common Boiler Problems We Repair

Boiler faults we diagnose and repair across Dublin

From minor faults to more involved repairs, our engineers work through the full range of gas boiler problems homeowners, landlords and businesses experience.

No Heating

Radiators stay cold and rooms fail to warm up despite the boiler running.

Possible causes

Thermostat faults, pump issues, diverter valve problems or a system lockout.

No Hot Water

Taps run cold or only produce lukewarm water, even with the boiler switched on.

Possible causes

Diverter valve faults, heat exchanger issues or a failed sensor.

Low Boiler Pressure

The pressure gauge sits below the normal range, often triggering reduced performance.

Possible causes

A small system leak, a faulty pressure relief valve, or recently bled radiators.

Boiler Leaks

Visible water around the boiler casing or dripping from pipework nearby.

Possible causes

Worn seals, a failed valve, or a cracked internal component.

Strange Noises

Banging, whistling, gurgling or buzzing sounds coming from the boiler or pipework.

Possible causes

Trapped air, limescale build up, a failing pump or worn components.

Fault Codes

The display shows an error code and the boiler stops operating normally.

Possible causes

Ignition faults, sensor errors, pressure issues or component failures.

Pilot Light Issues

The pilot light goes out repeatedly or will not stay lit.

Possible causes

A faulty thermocouple, draught in the flue, or a gas supply issue.

Thermostat Problems

The boiler ignores temperature settings or the thermostat display stops responding.

Possible causes

Wiring faults, battery issues, or a miscommunication between thermostat and boiler.

Ignition Faults

The boiler fails to fire up when heating or hot water is called for.

Possible causes

A faulty ignition lead, a worn electrode or a printed circuit board fault.

Radiators Not Heating

One or more radiators stay cold or heat unevenly across the surface.

Possible causes

Trapped air, sludge build up, or a balancing issue within the heating system.

Intermittent Boiler Operation

The boiler works some of the time but cuts out or fails unpredictably.

Possible causes

Loose wiring, a failing component, or an intermittent sensor fault.

Central Heating Problems

Uneven heating, slow warm up times, or a system that never reaches temperature.

Possible causes

Circulation issues, sludge in the system, or ageing components losing efficiency.

Why Boilers Break Down

Understanding the causes behind common faults

Boiler breakdowns rarely happen for just one reason. Understanding the general causes can help you make sense of what your boiler is going through, without needing to become an expert yourself.

Wear and tear

Like any mechanical system, boilers experience gradual wear on moving parts and seals over years of use.

Component failures

Individual parts such as valves, sensors or circuit boards can fail independently of the boiler's overall condition.

Lack of maintenance

Boilers that go long periods without any attention can develop issues that build up gradually.

Pressure issues

Incorrect pressure levels place strain on the system and can be a symptom of an underlying fault.

Ageing systems

Older boilers naturally become more prone to faults as components reach the end of their working life.

Why Choose Professional Boiler Repair?

The value of getting it diagnosed properly

Accurate Diagnosis

Correctly identifying the fault avoids unnecessary work and gets to the real cause.

Safety Considerations

Gas boilers require careful, competent handling for the safety of your household or premises.

Long Term Reliability

Careful, considered repairs carried out to a high standard every time.

Frequently Asked Questions

Answers to common boiler repair questions

Boilers can stop working for many reasons, including low water pressure, a tripped fault code, an ignition problem, a faulty component, or a lockout triggered by a safety sensor. Because several different faults can produce similar symptoms, a proper diagnosis by a qualified engineer is the safest way to identify the actual cause.
First check your thermostat settings, timer programme and that your boiler is powered on and showing no error codes. If everything looks normal but you still have no heating, it is best to arrange a diagnostic visit so an engineer can identify the fault safely.
A loss of hot water is often linked to a faulty diverter valve, a heat exchanger issue, low pressure or a broken component within the boiler. As with most boiler faults, the exact cause needs to be confirmed through inspection rather than guesswork.
Pressure that keeps dropping is commonly caused by a small leak somewhere in the system, a faulty pressure relief valve, or air trapped in the radiators. Pressure that is consistently too high can also point to a fault that needs professional attention.
Many leaks can be repaired once the source is identified, whether that is a seal, valve, pipe joint or internal component. An engineer will need to inspect the boiler to confirm whether a repair is possible or whether a part needs to be replaced.
Error codes vary by manufacturer and model, and each one points towards a different type of fault, from ignition failure to pressure or sensor issues. Rather than relying on generic online explanations, it is safer to have the code checked against your specific boiler by an engineer.
This depends on the age of your boiler, the nature of the fault, and its overall condition and repair history. An engineer can talk you through the options after diagnosis so you can make an informed decision that suits your circumstances.
Repair times vary depending on the fault and whether parts need to be sourced. Some issues can be resolved during an initial visit, while others may require a follow-up appointment once the correct part is available.
Many older boilers can still be repaired, provided the required parts are available and the unit is in otherwise reasonable condition. An engineer can advise whether a repair is practical for your particular model.
Banging, gurgling, whistling or buzzing sounds can be caused by air in the system, limescale build up, a failing pump or general wear on internal components. Unusual noises are worth having checked before they develop into a larger fault.
Cold radiators, or radiators that are only cold at the top or bottom, are often caused by trapped air, sludge build up, or a problem with the boiler's circulation. An engineer can identify whether the cause sits with the radiators or the boiler itself.
