If you have the unfortunate problem of a boiler breakdown in winter and you have to replace your gas boiler or you are simply looking to upgrade your gas boiler then there are a few things you need to consider when choosing what type of boiler to install in your home. The size of your boiler, the type, construction, and energy efficiency will all have an impact on your home and your energy bills. You should take some time to consider your options and think carefully about which boiler to choose.
Below is some information on the regular or ‘conventional’ gas boilers, system gas boilers and combination or ‘combi’ gas boilers. (System boilers are very similar to conventional boilers.)
A combination or combi boiler is both a high-efficiency water heater and a central heating system boiler in a single compact unit. Combi boilers heat water directly from the mains when you turn on a tap, so you won’t need a hot water storage cylinder or a cold water storage tank in the attic.
They are also very cost-effective and energy-efficient as water is heated instantly rather than being heated and then stored in a cylinder. An added benefit is that hot water is delivered at mains pressure, which means that you could get a powerful shower without the need for a separate pump.
System boilers require a cylinder for storing hot water, however the major heating and hot water system components are built into the boiler itself, making it quicker and easier to install. In addition, there is no need for a tank in the attic, so it can be an option in a home with little or no attic space or where the space is earmarked for a conversion.
These boilers are also compatible with solar water heating systems, which deliver environmental benefits as well as lower energy bills.
Regular boilers (sometimes known as conventional or heat only boilers) are ideally suited to homes that already have a traditional central heating and hot water system which is linked to a separate hot water cylinder. These boilers also need a cold water storage tank in the attic to feed the hot water cylinder as well as a tank that maintains the water level of the central heating system.
A regular boiler may be the best option for replacing an existing boiler if the property has an older radiator system, as it might not be able to cope with the higher water pressure that is delivered by system or combi boilers.

Everyone will agree that there are many benefits related to replacing your old gas boiler with a new high efficiency condensing model. For example, even the very best non-condensing gas boilers that are in perfect running order operate at an efficiency level of, at most, 70% (the vast majority of non-condensing boilers have a considerably lower efficiency rating). By contrast, a modern A-rated high-efficiency gas condensing boiler can run at efficiency levels of up to 98%.
How much money will I save on heating bills if I upgrade my Gas Boiler?
A gas boiler’s efficiency rating directly translates into monetary savings. In other words, if you replace a gas boiler that runs at 65% efficiency with a high efficiency condensing unit that has an efficiency rating of 98% you will be using 33% less fuel to heat your home, meaning your total heating bill for the year will be reduced by a third.
When you consider that gas prices increased in October, bringing the rise in gas fuel costs since 2011 to over 32%, replacing your old gas boiler with a high efficiency condensing unit will bring your heating bill down to the same level that it was at three years ago – a massive saving!
How can I save money when replacing my Gas Boiler?
One of the main things putting people off replacing their old gas boilers is the perceived high cost of purchasing a gas boiler upgrade and installing the new high efficiency condensing boiler itself. Fortunately, there are a number of ways in which you can greatly reduce this cost:
The SEAI (Sustainable Energy Authority of Ireland) offer two main types of grant which can be availed of when upgrading your gas boiler. When having a full gas heating system upgrade undertaken, which involves getting in a high efficiency condensing boiler as well as heating controls installed, you can save a massive €560 off the cost of the job.
If you do not need to replace your boiler you can still avail of a SEAI grant of up to €400 should you decide to have heating controls installed. Heating controls will allow you to take better control of when and how your home heating system is operated, which means you can further reduce the price of your fuel bills by not letting any gas go to waste.
Building Energy Rating Grant (BER)
The Building Energy Rating (BER) process involves calculating how much energy your home uses up and how much carbon it produces on a yearly basis. All homes in Ireland, whether they are purchased or rented, must have a BER certificate. When seeking to improve your home’s energy efficiency you can apply for a BER grant up to the value of €80.
