Cost of Replacing a Gas Boiler in 2024

what is the cost of replacing a gas boiler in Ireland?

The assumed cost of replacing a gas boiler means many of us settle for second-rate central heating systems. However, the importance of a reliable boiler can’t be overlooked. An efficient boiler keeps our homes warm during the winter months and brings us hot water on demand when we need it most. 

If you’ve had your current boiler for more than 15 years, it’s likely overdue for an upgrade. Even if your radiators are working and hot water is flowing, an inefficient boiler may be costing you a small fortune.  

By swapping out your current system for an A-rated model, you can make considerable savings on your energy bills. Not only that, but your central heating system will benefit from enhanced performance and fewer boiler breakdowns. 

Need more convincing that it’s time to think about replacing your gas boiler? Read on for more reasons why now’s the time to make the switch and why a one-off cost can save you money in the long run.  

How Do I Know I Need To Replace My Boiler?

Although shelling out for the cost of a new boiler in Ireland can seem daunting, there are times when replacing your current model is unavoidable. Even the best heating units will eventually encounter boiler issues. A decent model should perform well for up to 15 years. However, there are plenty of signs to look out for to determine whether or not it’s time to consider a replacement.  

Energy Efficiency Ratings

If you’ve purchased a boiler in the last 15 years, it should come with an energy efficiency rating. The best-performing boilers are rated an “A”, operating at around 90% efficiency. The scale goes all the way down to “G”, with these models rarely operating at efficiency levels above 70%. 

As you’d expect, the more efficient your boiler is, the less money you’ll be spending to heat your home. If you’re still using a system rated “C” or lower, you’ll quickly recoup the cost of replacing a gas boiler when it comes to energy bill savings.  

Your Heating System Isn’t Working Properly 

Your boiler is what keeps your home warm and hot water running. If you’re struggling on both counts, the issue almost certainly lies with your boiler. An easy way to spot a problem boiler is an uneven central heating system. Are some rooms much warmer than others, even though they’re equipped with identical radiators? If you’ve researched how to flush radiators and invested in power flushing and are still having issues, it’s time to investigate new boiler costs in Ireland.  

Unexplained Shutdowns 

One of the most common gas boiler issues is regular shutdowns. There’s a multitude of reasons why this might be happening. You may be dealing with low boiler pressure or a damaged thermostat. These issues are easily remedied, but if replacing components doesn’t solve the problem, absorbing the cost of replacing a gas boiler makes sense in the long run.  

Regular Breakdowns and Repairs


Sometimes, adjusting the pressure on your boiler is enough to get it working again. However, this shouldn’t be a daily or weekly occurrence. If you’re having to make adjustments frequently and the issue seems to be getting worse, this is a major sign your boiler needs replacing.

Even if your boiler can be repaired, there’s no guarantee you’ll be able to find replacement parts. The older your boiler is, the more difficult it will be to track down those essential components. How often should you service your boiler? Every boiler should be serviced once a year, but a poorly performing model is probably going to need more attention.

How much is a new boiler?

The price of new boiler systems varies depending on a few factors. A boiler from an established brand may command a small premium, while those systems with advanced smart home features will also command more than a run-of-the-mill unit. Generally speaking, you’re looking at a minimum of around €2600 to replace your boiler with a new model. When you compare this against the cost of new gas boiler systems, this is pretty reasonable.

What is a combi boiler?

Combi boilers bring you the best of both worlds, serving as a central heating component and a water heater. A combi boiler provides you with hot water whenever you want it, meaning you won’t have to wait around for your temperatures to start rising. What’s more, it means you don’t have to find space to accommodate a bulky storage cylinder or tank. How much is a combi boiler in Ireland? With starting prices of around €2600-€3000, they’re no small investment. However, when you consider boiler replacement costs for older models, they’re still the most viable choice.

How long does it take to install a new boiler?

Installation times for boilers vary, depending on the type of system you’re having fitted and the complexity of the installation itself. In an ideal case, your installation should be completed within six hours. However, more complicated installation tasks can take several days.

How many years do boilers last?

Boilers are becoming more durable as time goes on. Many boiler models released today have expected life spans of around 10-15 years. While it’s a good idea to replace an outdated boiler with a more efficient one from time to time, you can extend the life of your current one by paying attention to DIY and utility complaints.
