When should I get a Gas Boiler Replacement?

The Sustainable Energy Association of Ireland (SEAI) recommends that you should replace or upgrade your gas boiler if it is more than 15 years old. Even if there are no apparent problems, it’s unlikely to be running above 70% efficiency (new gas boilers are more than 90%) and reliability is likely to be an issue.

    • Help it run more efficiently, reducing your heating costs
    • Reduce your heating costs by up to 25%
    • Improve reliability and safety
    Improve your Building Energy Rating (BER)



How Much Can I Save by Getting a Gas Boiler Replacement?

Save up to 20% operational improvement in efficiency. That means more than 25% in fuel savings. Combine it with zoned controls and your savings can increase to over 35%.

In other words, you can cut your fuel bills by a third by replacing an older, low efficiency gas boiler with a high efficiency gas boiler and zoned controls.
