ATAG i24S System Boiler Pros and Cons
Building on the impressive performance metrics, let's evaluate the real-world advantages and limitations of the ATAG i24S system boiler.
You'll love the exceptional 94% energy efficiency rating and compact design that fits neatly into your kitchen cupboards. The stainless steel heat exchanger means you won't need to worry about durability, while smart control compatibility lets you adjust settings from your phone.
However, there are some trade-offs to assess. The higher upfront cost might make your wallet wince, and you'll need a separate hot water cylinder. Finding an ATAG-approved installer can be tricky in some areas.

For many homeowners, the long-term efficiency savings help offset the initial investment.
How Does The ATAG i24S System Boiler Compare To Similar Models From Other Manufacturers?
