Accredited Gas Boiler Installer

Gas boilers are built to last, but with time and use they can become tired and in need of the occasional repair. The reasons gas boilers stop working or stop working effectively are all related to age and use. Over years of constant use, a boiler begins to rust and tire.  Ultimately, a boiler will need replacing but there are repairs that can be made to keep it safe and efficient before it gets to that stage.

We offer a specialist boiler service based on more than 19 years of accredited experience by major boiler manufacturers. When your gas boiler needs repairing, you can rely on 24 Hour Plumber to be with you any time of day or night. Our emergency boiler repair service is available 24 hours a day, 7 days a week.  Alternatively, for non emergencies, we can arrange for one of our accredited gas repair plumbers to repair your boiler at a time that suits you.

Faced with an emergency as water was flowing freely across floor in a rental property. Unfortunately the tenant did not report the problem. Turned off water at mains and called 24 hour Plumber service. I was told plumber would be with me within 2 hrs. True to word plumber arrived within stated time and made an immediate repair. He stayed whilst tank in attic refilled to ensure repair was true. The plumber was an absolute gentleman. From this experience I will definitely use this service again.

Great service today from Jarlath. Very professional service and very knowledge about the issue with a leak in my shower and also with a kitchen tap. Would certainly recommend 24 Hour Plumber. Most importantly these days they are very reliable and in my experience turn up to do the job when scheduled!

I rang in a panic on a Saturday due to a broken water pump and was told that the earlier appointment would be Wednesday but I'd go on a cancellation list. I got a call on the Sunday night to advise that there was a slot available Monday morning. The plumber rang to discuss the issue before arrival, quotes were completely transparent and the first check from the plumber was fixing the issue rather replacing the pump I.e. trying to save me money. A new pump was required and installed to perfection. Would recommend and will use again. All staff very nice to deal with also

Very impressed with this business. In the first place - they called backed after missing my call! A simple thing but it made all the difference! I really think they have a winning combination of someone professional and organised at the end of the phone someone else who's good at the plumbing bits! Pam was on the phone and Ryan did the job on the day and went over and beyond! Very very impressed And they were very good value.

We had a blocked toilet do I sent an email to the 24 hour plumber. I never used then before and they were not recommended yo me. Pamela rang me at 9. The morning didn't suit so we agreed that someone would call after 1. Ryan was in touch around 3.30 to say he would be with me within the hour. He arrived on time and thankfully solved our blocked toilet problem. He was very professional, a real gent who gave a 5 star service.Great service at a reasonable price.Thank you.

Trevor and Spence did a very good job. Very professional. Took a while to get someone out to the house (They are a busy team and it was not an easy job!), but definitely worth waiting for.

Ryan arrived on time and replaced two taps and a toilet valves/flusher - really great job. He was very pleasant & capable and explained the problems and choices to me. Based on my positive interactions with the company, I'd recommend using them and will certainly add them to my list of contacts for future maintenance and emergency jobs.

Absolutely fantastic service from Trevor. I contacted 24 Hour Plumber to fix my gas boiler and to give the boiler a service. Trevor arrived that evening and got to work. It took longer than he had expected due to pre existing issues with the boiler which he sorted out. All working perfectly again now. I was very impressed by Trevor, he is very professional and courteous and went above and beyond what I would have expected. Also very reasonable price given the amount of time involves. I have no hesitation in recommending 24 Hour Plumber, if there was an option to give more than 5 stars I would give it.

As a fellow tradesman (electrical contractor) you are always on the lookout for professionals in the other trades who you can recommend to your customers and rely on to assist you with your own projects. Trevor Stronge plumbing is hands down the best plumbing outfit I've found in 20 years. A Knowledgeable professional with a high attention to detail. If you have a plumbing system of any kind, having Trevor's number is a essential.

Very happy with the work performed (toilet and vanity unit installation). The job wasn't straightforward. The guy was very committed and stayed late to finish the job properly (no shortcuts taken). He was also very pleasant to deal with. Thanks for your efforts R. Much appreciated, Eamonn.

If you are ever in need of a plumber.. then definitely call Trevor!! He tried to fix the problem however, we ended up needing a new tank (not his fault, we had tried to DIY it) and so off he went to get it for us and installed it the same day. Meticulous, clean worker and just a lovely guy. Definitely our go to plumber forever. FYI.. offer him a cuppa!

Trevor is the most amazing plumber I've met in my life. He has the industry knowledge and experience to not only fix what is broken now, but to also point out things that will break if not fixed soon. The quality of his work is so outstanding, that I recommended him to all my Dublin friends and rather delay even important jobs than giving them to a new plumber.He's extremely helpful and works very hard to quickly help people especially in emergency plumbing situations, but also always found time for my non-emergency jobs.

Very timely response on a Sunday afternoon. Spent a long time diagnosing the problem, explained it fully, resolved it and sorted another plumbing problem at the same time. Trevor is a what I would call a professional plumber. In what can seem to us lay people like the emperors new clothes, he explains and simplifies technical issues so at least you have some handle on the problem. Courteous, efficient and effective.

When it comes to replacing boilers and heating systems in Dublin, we offer you our 16 years of plumbing experience to make it as stress free for you as we can.

Gas Boiler Replacement Dublin – Boiler types for homes

Home size and needs vary all over Dublin city and county. If the gas boiler you have is not meeting your needs, we can replace it with one that will. 

Of all the types available, combination boilers, also known as combi or combi-boilers are the most common gas boiler choice for Dublin households. Favoured because they heat both your water and your home. Combi boilers are ideal for homes that are short on space as the design is compact and there is no external tank. 

If you have a bigger home or a high demand in your home for hot water, a system gas boiler could be a better choice than a combi boiler. System gas boilers are bigger than combination boilers as are heat only boilers. Both of these have more components and additional tanks. They are, however, a good choice if there are a few people living in the home. 

Which boiler brand is best? 

We understand that budgets and space vary considerably between homes, this is why we offer a choice of boiler brands to suit every budget and home. Costs and warranty vary from brand to brand, we would be happy to talk you through the options available to you. Book an appointment with one of our gas installers here.

The gas boiler brands we work with the most are listed below. All of these are expert brands with high-efficiency gas boiler products:

Alpha has three types of combi boiler to choose from including their newest product the E-Tec Plus which comes with a 10 year warranty as standard. Alpha also have impressive regular and system only boilers.

Baxi is manufactured in the UK and well known brand Ireland. They offer all types of boiler and boast that they have ‘have a range, model and output suitable for all domestic gas heating installations’. 

Ferroli has electric and gas boilers. Including wall hung combi and condensation boilers. Some Ferroli boilers have accessories for your boiler like WiFi remote control. 

Glow Worm has options of all three types of gas boiler. Warranty differs depending on the boiler you choose but the Glow Worm energy combi boilers do come with a 7 year, out of the box, warranty. 

Ideal boilers have a heater solution for every Dublin home type. Whether your home is a bungalow, flat, detached or semi-detached. They have a handy tool on their website that helps you choose the best boiler type. Alternatively, 24 Hour Plumber would be more than happy to advise you. 

Most Ravenheat models have a built-in 7-day digital timer with the control panel. Other brands do have this too as it is a useful way to keep your energy bills down by controlling your boiler use. 

Remeha has more than 85 years of home heating expertise. Remeha focussed on commercial heating and a good choice if you are heating a venue or large Dublin office building rather than a home. For your commercial heating needs contact a member of the 24 Hour Plumber team here – contact page.

Vaillant has an award-winning boiler range, each boiler in which is handmade in the UK. They pride themselves on performing 900 safety checks before shipping a boiler. 

The Vokera boiler range is vast and suitable for most budgets, whilst Viessmann is a German business with a boiler range that is globally popular. They design their systems with the future in mind and many of their products are smart home ready. 

Worcester Bosch is a reliable brand with a range which includes combi boilers, system and regular boilers. 

Within the boiler range by Wolf is the CGB-2 a great boiler option for detached houses and apartments. This boiler is compact and is mounted on the wall to save space. 

Pro Plumber tip: Check the warranty for all your new appliances as soon as they are installed. Most brands now require you to register your warranty online or by email for it to be valid. Read the terms and conditions carefully. 

How to tell if your boiler needs replacing 

There are a number of clues that it is time for your boiler to be replaced. We have listed some of the things to watch out for below.

If you are not sure that your boiler needs replacing, contact us today to organise a checkup.

The colour of the flame

The flame of a gas boiler should be blue. If the flame is yellow instead this could indicate the presence of carbon monoxide. This is a very dangerous and odourless gas. If the flame of your boiler is yellow. Call an emergency plumber immediately and go somewhere safe like a neighbour’s house. 

The smell

There should be no smell from your gas boiler. If you smell gas. Open the windows and leave the house immediately. Call the Gas Networks emergency number 1850 205 050. 

Rising heating or repair costs

An unhealthy boiler has to work harder to heat your home and water. As a result, you might notice a spike in your gas bills. You might also need to have it repaired more often. A newer, healthy, boiler should only need maintaining with an annual checkup. A regular need for repair suggests it is coming to the end of its days. 

Your boiler is acting strangely

On average, a home boiler has a lifespan of approximately 15 years. After that, it will start to wear out and deteriorate. It might become unreliable, failing to heat your home like it use to. In some instances, a boiler can start to make strange noises as its mechanisms deteriorate. 

“I knew something was wrong because every time the heating came on the boiler would make a strange squeaking noise. I was worried that getting a gas boiler changed would be a hassle. 24 Hour Plumber put my mind at ease, explained everything and had the new boiler in within a day. It was easy in the end”, Becca Dunne, Dublin West
