oil Boiler installations in Dublin

24 Hour Plumber repairs and services all brands and types of boilers (internal and external oil boilers). Oil boilers are built to last, but with time and use they can become tired and in need of the occasional repair. The reasons Oil 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 oil boiler service based on more than 19 years of experience. When your Oil boiler needs repairing, you can rely on 24 Hour Plumber to be with you any time of day or night. Our emergency oil 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 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.

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.

Boilers break down for all manner of reasons and at 24 Hour Plumber we know them all and how to repair them!  Here are a few of the most common issues that people experience and why they mean that your boiler might not be working properly.

Your Boiler is Making Banging Noises

Do you ever get woken in the night by your boiler making a banging noise when the heat comes on?   Or maybe you have noticed your boiler making strange gurgling and rattling noises. This is common in older boilers but can happen to boilers of any age for a few reasons. 

In some parts of Dublin hard water can create a build up of sludge and limescale that is interfering with your boiler function. Within your boiler there is something called a heat exchanger. Water flows through the heat exchanger but when there are sediment deposits in the way, the water can not get through properly and starts to get too hot. This creates a noisy effect that we in the plumbing trade know as Kettling.

Another reason for a noisy boiler is trapped air somewhere in the heating system. If this is the case then our plumbers can quickly and effectively bleed the radiators in your home to remove the airlock. 

The Pilot Light Has Gone Out

On the front of some older boiler types, you should see a small window looking into it. This tiny window is to check the pilot light. A small blue flame that is always on.  The pilot light lights the gas that is being released from the gas pipe into the boiler to heat the burner. If the pilot light is out and will not come back on then there could be a fault with your boiler. 

Safety note: If the pilot light will not come on and you can smell gas, call Gas Networks Ireland as quickly as possible. A gas leak of any size can be dangerous. It is important that Gas Networks Ireland make your home safe before you call a registered gas installer like 24 Hour Plumber

Your Heating Isn’t Coming On

A sure sign that your boiler is in need of repair is that there is no hot water or heat in your home. This can be caused by a number of reasons, including those we have touched upon already such as limescale and airlocks. Another cause could be low water pressure. This is a very common problem for homes across the Dublin area and one that we deal with daily. 

Alternatively, a part of your boiler could be broken or worn. Our plumbers are experienced with boiler repair and will know which parts to check for breaks. Diagnosis is quick and our team will have your heating back on in no time. 

Pro Plumber Tip: The first thing to check when your heating won’t come on is the heating thermostat. Try switching the thermostat up or down a touch and see if the heating works then. Sometimes if a heating system believes that rooms are at the required temperature it will switch off.

Your Boiler is Leaking

Even a small leak from your boiler could signal a need for repair. Left untreated, small leaks can create further issues and a loss of heating. Leaks on a boiler are usually a sign of corrosion for older boilers (5 years or more). Seals within the boiler can wear away with time and use and may need replacing. 

If you notice a leak from your boiler, switch off the water in your home. The valve to do this will be located under the sink, on an outside wall, in a utility room or a basement, under the stairs. Once the water is switched off, call an experienced plumber.

Does My Boiler Need Repairing or Replacing? 

The best way to find out if a new boiler is needed is to have a plumber look at it for you. Call 24 Hour Plumber to arrange for a plumber to visit your home and assess your boiler at your convenience. We strongly advise our customers not to delay in getting boiler problems checked. We understand the cost and inconvenience of getting a boiler replaced can be a worry but believe that the sooner a problem is caught, the quicker it can be resolved. Hopefully with a quick and thorough repair.
