Boiler Upgrades from €2,600 | RGII Registered

If your boiler is more than twelve to fifteen years old, there's a good chance it's costing you far more than it needs to. Older boilers lose efficiency year on year, meaning you're paying for heat that's disappearing straight up the flue. A modern A-rated replacement can cut your heating bills significantly while giving you a far more reliable system.

Why upgrade your boiler now

Boilers rarely fail conveniently. The most common time for an old boiler to break down completely is during the coldest weeks of winter, exactly when you need it most and exactly when engineers are busiest.

Upgrading on your own schedule, rather than waiting for an emergency, means you get the boiler you actually want, installed properly, with time to compare options rather than settling for whatever's available at short notice.

Beyond reliability, modern A-rated boilers are dramatically more efficient than anything installed before 2010. That efficiency gain shows up directly on your energy bills, month after month, for the lifetime of the boiler. Combined with smart heating controls, many households see a noticeable drop in their annual heating spend within the first year of upgrading.

Serving Dublin, Kildare and Wicklow

Revolution Gas installs boilers right across Dublin city and county.

In Kildare, we work throughout Naas and the surrounding areas including Celbridge.

Throughout Wicklow we cover Bray to Greystones and the surrounding areas.

Wherever you're based across these three counties, our engineers can carry out a survey, provide a clear quote, and schedule your installation at a time that suits you.

Choosing the right boiler for your home

Not every home needs the same boiler. Combi boilers suit most apartments and smaller households with modest hot water demand, while system and regular boilers are often the better fit for larger homes with multiple bathrooms.

During your free survey, we'll assess your property's size, hot water usage, and existing pipework to recommend the boiler that actually suits your household, not just the cheapest option on the shelf.
