ATAG has been designing and manufacturing boilers for almost 70 years. In that time we’ve set the highest standards for energy efficiency and engineering excellence across the world.


What sets ATAG apart is the fact that we operate in so many countries across the world, with each having their own strict engineering standards. We’ve combined all these requirements that today culminates in our ‘i’ range of ATAG boilers. They’re built to last using the highest quality stainless steel and brass components. Not only are they the most energy efficient boilers in Europe, they also have the lowest NOx emissions meaning they’re kinder to the environment.

At the heart of every ATAG boiler is our revolutionary iCon heat exchanger, which has unrivalled performance and efficiency levels. It’s made from high grade stainless steel and, uniquely, it maintains 98% of its original efficiency levels throughout its lifetime.

Throughout the world, ATAG boilers are installed in large commercial buildings as well as domestic properties and they are trusted to deliver unrivalled performance, efficiency and supreme reliability. This helps to explain why ATAG boilers are also the number one choice for professionals such as architects and design engineers. In addition to winning numerous global awards, UK consumers also rate ATAG the number one boiler manufacturer on independent review site Trustpilot.
