If your oil boiler is getting old, unreliable, or costing you too much to run, it may be time to replace it. At Arc Heating & Plumbing Services, we specialise in oil boiler replacement in South Dublin. We work across all local areas including Tallaght, Dundrum, Clondalkin, Lucan, Rathfarnham, Templeogue, Terenure, Walkinstown, Ballyfermot, and Crumlin.
Many homeowners wait too long to replace an old boiler, thinking repairs will keep it going. But in most cases, you end up spending more on callouts and fuel. A modern oil boiler is more energy-efficient and reliable. It also provides better heating and hot water control, especially when paired with smart thermostats.
Signs You Need a New Oil Boiler
You might not know exactly when your boiler is beyond repair, but there are warning signs to look for:
-
Strange noises like banging, knocking, or whistling
-
Inconsistent hot water or poor radiator heat
-
Frequent breakdowns or error codes
-
High oil usage and rising heating bills
-
Your boiler is over 15 years old
If you’re dealing with any of the above, it’s worth getting an inspection. We’ll take a look and let you know your best option. If it can be repaired safely and affordably, we’ll say so. If a new boiler is the smarter choice, we’ll give you a fair quote and explain your options clearly.

Grants for Oil Boiler Replacement
There are some grant options available in Ireland that can help reduce the cost of upgrading your heating system. While there aren’t direct SEAI grants for oil boilers alone, you may qualify for support when combining your upgrade with heating controls or insulation. These improvements can improve your BER rating and save you money in the long run.
We’ll guide you through the grant process, explain what’s available, and help you with the paperwork if you’re eligible. Many homeowners miss out on funding simply because they’re not aware of it.
Frequently Asked Questions
How much does it cost to replace an oil boiler?
Prices can range from €2,500 to €4,500 depending on your home size, the boiler you choose, and if extra upgrades are needed. We provide a full quote upfront so there are no surprises.
