Five Signs a Boiler Service is Needed for Your Boiler

Five Signs a Boiler Service is Needed for Your Boiler

Boiler Service


A boiler service is very important, a well-maintained boiler can last up to 15 years and while an annual boiler service will help to ensure the best possible lifespan of your central heating system, the older your boiler gets the harder it will be working to heat your home.


A boiler in need of replacement is unlikely to be energy efficient or cost effective, but more importantly, it could be a danger to you and your family.


Serious boiler problems can lead to more than a lack of heat. A serious concern is carbon monoxide poisoning that can be fatal if it goes unnoticed. If any of these signs are manifesting themselves, have a registered RGII technician (Gas Boilers) or a registered OFTEC technician (Oil Boilers) out to have a look at your boiler.


1. It has not been serviced in a year

Regular servicing is very important. So if you have not serviced the boiler in more than a year, don’t wait for the serious signs to consider getting it serviced. Your boiler is subject to wear and tear and regular maintenance is necessary to ensure your heating system is efficient.


2. The Pilot Light keeps Going Out

A pilot light that will not stay lit is a sign that it is not functioning properly. The pilot light is the ignition source for the boiler; if it does not stay lit then the burners for the boiler cannot be turned on.
Also if the pilot light burns a yellow flame, this could be a sign of carbon monoxide and you should call a registered technician straight away.


3. Your Boiler is Making Strange Loud Noises

If your boiler is making an unusual noise, it won’t take long to spot it. Your boiler heating up is one of those sounds that will fade into the background; that is until something is not working properly.
There could be a number of faults that are the cause of any strange or loud noises that are not typical with the boiler, this will be often due to wear and tear of the pump and fan.
It is important to have it checked at the earliest opportunity by a registered technician.


4. There is a Strange Smell From Your Boiler

One of the signs that your boiler needs a service is that a strange smell coming from it. This happens when there is a gas or oil leak in your boiler. Leaks can lead to carbon monoxide poisoning if unchecked.
If you notice dark marks on the boiler casing, you should contact a registered technician immediately.


5. Your Home Doesn’t Feel as Warm as it Should

If your home feels cold even with the heating switched on, then the boiler could be at fault. It is important that an accredited plumber or RGII registered technician (Gas Boilers) investigates the reason why your home is not heating up as it should be. Assuming that all of your radiators are in good working order in which case a power flush might be needed on the heating system but if the radiators are working then the boiler will need to be checked.


An annual boiler service is important to keep your boiler well-maintained and to ensure the best possible lifespan of the boiler.

Gas Boiler Maintenance

To ensure a long life for your gas boiler and natural gas appliances, it is important to have them serviced regularly. Appliance manufacturers recommend that all appliances should be serviced annually.

An annual boiler safety checks and gas boiler service are carried out by a professional RGI service engineer ensures that your boiler is functioning properly. Regular servicing of your boiler is important as it ensures that the boiler is working to the specifications designed by the boiler manufacturer. This will help prolong the life of the boiler as well as reduce the risk of faults and expensive repairs down the line.

Gas boiler services can only be carried out by an RGI (registered Gas Installer) who represents the RGII (Registered Gas Installers Ireland).

The Service Engineer will complete 19 detailed checks and tests when carrying out a boiler service. All Visual Checks and Tests Applied are in accordance with Irish Standards 813:2002 as laid down by the National Standards Authority of Ireland for Domestic Gas Installations.

Here you will find a complete gas boiler service checklist which outlines everything that you should expect/demand from your gas contractor when they are servicing your gas boiler.

Reasons to have your Gas Boiler Serviced Annually

Save money on repairs.
Full-blown boiler problems can often develop from minor faults. An annual service will increase the chance that these are picked up on and fixed before they become a problem, saving you money and future gas boiler repairs.

Reduce your heating costs.
The engineer who undertakes your annual boiler service will make sure that it is running as efficiently as possible. This will go a long way towards making sure that you minimise your heating bills.

Carbon monoxide can kill.
Boilers that aren’t properly installed, maintained or ventilated can produce carbon monoxide. Symptoms of carbon monoxide poisoning include headaches, drowsiness, nausea, breathlessness and stomach pains. Signs are hard to spot and can be confused with tiredness or a cold. Unfortunately, this silent killer can’t be seen or smelt, so it really is important to make sure your boiler is serviced at least once a year.

If you’re a landlord, it’s the law.
Landlords have a responsibility under Statutory Instrument SI.534 of 2008 Housing (Standards for Rented Houses) Regulations 2008 to ensure that the gas installation in the house or apartment shall be maintained in good repair and safe working order. The Technical Guidance Document in relation to this Regulation states that a current Declaration of Conformance certificate for an IS.813 Annex E inspection issued by a Registered Gas Installer for the gas installation in the house or apartment will prove compliance with the regulations.
