Most houses in Ireland are equipped with a gas boiler as their main heating system.

They make our homes comfortable by providing heat and hot water — and they are very reliable and efficient in doing that. But your boiler can wear down over time even if you operate it correctly and maintain it well, and a gas boiler repair might be needed.

Regular servicing is half the battle when it comes to keeping a boiler working correctly. A well-maintained unit from a good brand like Viessmann or Worcester-Bosch will give you many years of faithful service even after the warranty period.

It’s also important to recognise the signs that something is wrong so that you can contact us in time for a gas boiler repair. Parts can fail mechanically or experience electrical faults and it’s worth having them replaced professionally for the safety of your family.

We are a team of skilled plumbing and heating technicians ready to take care of any problem and get your heating system working again.

Gas Boiler Repair Ireland

In Ireland, we get more months of cold weather than most other countries, and keeping our gas boilers in a good state of repair is essential if we want to keep our homes warm.

Even in the summer, your boiler can show you signs that something is amiss. When the weather is good and you don’t need the heating on, your boiler still needs to fire up regularly to give you hot water. During these times, it’s just as likely for it to develop problems that can be fixed easily if you spot them in time and contact a company that does gas boiler repairs in Ireland.

We recommend you try getting your system serviced in the summer or early autumn, which will make it much less likely for problems to pop up in the winter months when you need your heating the most. Once the weather takes a turn for the worse, heating specialists tend to become a lot busier and it can be hard to find someone on short notice.

Our qualified gas boiler repairmen can take care of all your needs if you are in Dublin or the surrounding areas. Our services include diagnostics, yearly maintenance, emergency repairs, and — when the time comes — we can replace your boiler with a new one with a long warranty period.

Booking a check-up or repair with us is easy. You only need to send us a message or give us a call and describe the problem, after which we can schedule a callout for a day and time that suits you.

Most Common Gas Boiler Repairs

It’s usually obvious when the time has come for a gas boiler repair. Your heating system will give you clear signs that it needs attention, and if you watch out for those signs you can prevent the problem from getting bigger and more costly.

Here are the tell-tale symptoms of the most common gas boiler problems you can come across.

No Heat or Hot Water

The fastest way for your boiler to tell you that something is wrong is for it to stop working altogether. Your house might be chilly when you arrive in the evening, or the water coming from your taps in the ‘HOT’ position might be just as cold as the other side.

There are a few reasons why this could happen. Something might be wrong with the thermostat, in which case the boiler is never aware that it should fire up. On the other hand, the thermostat might be working fine and the boiler is not doing its job.

Check the schedule of your thermostat and make sure it’s not turned off or in Holiday mode. You should also check your boiler pressure, keeping it between 1-1.5 bars and well within the green range of the gauge. You can increase or decrease the boiler pressure yourself, but you will need to check the manual because the steps are different from brand to brand.

If you did all this and still have no hot water, give us a call and let us solve the problem for you.

Noises Coming from the Boiler

Banging noises. Popping sounds. Rattling or excessive vibration.

There are plenty of sounds that your boiler can make to alert you of an issue. If you hear anything out of the ordinary coming from inside the appliance, turn it off from the thermostat and contact a specialist.

Noises like these can mean that there is a buildup of limescale in the system — which you can’t clean on your own — or that a part is failing and has to be replaced.

Gas Boiler Leaking or Dripping Water

Finding water under your gas boiler doesn’t necessarily mean that something is badly wrong.

If the amount of water is small, try adding more pressure into the boiler. This is pretty easy to do and is explained in the manual that came with it.

The problem can also be caused by a worn (or poorly aligned) seal or a broken heat exchanger, especially if you find larger puddles under the unit.

If you tried to pressurise the boiler but the problem remains, send us your details and we will schedule a gas boiler repair so that you can be comfortable in your home again.

Boiler Pressure Too Low or High

Most boilers come with built-in ways to increase or decrease their pressure.

There is usually a small key or knob that you can turn to let more water into the system, which increases the pressure. For letting pressure out, the easiest way for a homeowner is to bleed a radiator.

Some systems might not be as straightforward as this. The valve that adds water to the system might be somewhere else, such as in your hotpress. If you are not sure that you can identify it, always do the safe thing and leave it to a service engineer.

Your hot water tank is most likely equipped with one or two immersion heaters, which can be used if you don’t feel safe using your gas boiler while waiting for a technician to come and fix it. Take care of this backup system because you can end up without hot water if your gas boiler breaks and you neglected to do an immersion heater repair at the right time.

Pilot Light Keeps Going Out

The pilot light is a flame that burns gas continually when your boiler is running. If it doesn’t stay lit, the boiler can’t keep your home warm and your showers hot.

Repairing the ignition system that controls the pilot light is not something you can do yourself. Dealing with this comes with many risks even if you turn off your gas at the meter.

Always call an insured gas boiler repair specialist and leave the matter in their hands.

Tips for Maintaining Your Boiler

All the gas boiler models sold and installed in Ireland are extremely well-regulated for safety, efficiency and overall build quality.

Out of the range of boilers that we supply, the Viessmann ones are made in Germany, and all Worcester-Bosch and Ideal units are produced in the UK. They are well-made appliances that will last through many years of use.

There are only a couple of things that you can do if you want to extend their life as much as possible. Follow these tips for maintaining your boiler and you will enjoy the benefits and cost-savings for a very long time.

Annual Gas Boiler Servicing

You should book a gas boiler specialist to carry out a full service every year. They will clean the unit, check for damage and malfunctions, fix any leaks and tell you if anything else is needed.

Getting your gas boiler serviced doesn’t usually cost much. Many times you will only pay a callout charge, but sometimes it can be a little more if some parts show signs of wear and need to be replaced.

It’s best to have it serviced before the start of the cold season. In the summer, a broken gas boiler is an inconvenience — but in the winter, it is an emergency. Doing it ahead of time will give you peace of mind and extend the lifetime of your heating system.

Detecting Gas Leaks and Carbon Monoxide

Gas leaks are easy to identify. These leaks are unlikely to develop if you get your boiler checked every 12 months. Natural gas has an unmistakable smell which you will notice very quickly so that you can take action.

Carbon monoxide is more dangerous than gas because it doesn’t smell. Test your detectors regularly and replace their batteries with new ones, unless you have a model with a 10-year battery.

If you think there is a gas leak or a buildup of carbon monoxide in your house, this is what you need to do: turn off the gas at the meter, open some windows and leave the house until the air is clear.

As soon as you are safe, call a professional to find the source of the problem and resolve it.
