Gas Boiler Replacement Dublin
Professional Gas Boiler Installation from RGI Registered Engineers
If your boiler is getting older, becoming unreliable or costing more to run and repair, it may be time to consider replacing it.
Corr Heating provides professional gas boiler replacement throughout Dublin, helping you choose the right boiler and heating setup for your home.
Established in 1982, our experienced RGI registered engineers can take care of your boiler replacement from initial assessment through to installation.

Is It Time to Replace Your Boiler?
A well-maintained boiler can last many years, so replacement isn’t always necessary.
However, you should consider replacing your boiler if:
- Your boiler is 15 years old or more
- It regularly requires repairs
- Replacement parts are becoming difficult or expensive to source
- Your heating bills are increasing
- Your boiler frequently loses pressure
- Heating your home is taking longer
- Your boiler is becoming unreliable
- You're planning to upgrade your heating system or controls
We’ll assess your existing system and give you straightforward advice on whether replacing the boiler is worthwhile.
Choosing the Right Boiler for Your Home
Corr Heating can install all types and makes of gas boiler, depending on what best suits your home and heating system.
While we can fit any suitable gas boiler, we generally use and recommend Ideal boilers due to their reliability, efficiency and strong range of options for Irish homes.
Before recommending a boiler, we’ll assess your existing heating system, the size of your property and your heating requirements to make sure the new boiler is properly matched to your home.

Benefits of Replacing an Older Boiler
- Improved Energy Efficiency
- More Reliable Heating & Hot Water
- Lower Risk of Unexpected Breakdowns
- Better Heating Control
- Quieter Operation
- Reduced Maintenance
- Improved Home Comfort
The actual improvement will depend on your existing boiler, heating system and heating controls.
Professional Boiler Installation
Your new gas boiler will be installed by an experienced RGI registered gas engineer.
We’ll take care of the replacement process, including removing the existing boiler, installing the new boiler and checking that your heating system is operating correctly.
Our priority is to provide you with a safe, reliable and properly installed heating system that works effectively for your home.
Upgrade Your Heating Controls
Replacing your boiler can also be a good opportunity to improve your heating controls.
Modern heating controls give you greater control over when and where your home is heated, helping reduce unnecessary energy use.
Depending on your existing heating system, options may include:
- Improved heating timers
- Room thermostats
- Thermostatic radiator valves
- Zoned heating controls
- Smart heating controls
We’ll advise you on what makes sense for your home rather than recommending upgrades you don’t need.
