iC Combination

Every ATAG boiler carries a 12-year warranty as standard with options up to 18 years and they’re professionally installed by our ATAG Selected Partners.

Our combination boilers come in a range of sizes designed to suit all needs, from a small flat to a large family dwelling, and are celebrated for
their efficiency.

In fact, thanks to our engineering excellence, an ATAG iC combination boiler can help to save up to £320 a year on your gas bills (Energy Savings Trust, 2017).

Compact and quiet, an iC combination boiler will fit neatly into the heart of your home. This makes it a perfect choice if you have limited space, or if you want to free up space currently allocated to a hot water cylinder.

Why not pair the ATAG iC combination boiler with the ATAG ONEZone to achieve a maximum A+.
