  2. Rated 5 out of 5

    Before buying out Atag boiler we searched the net for the best boiler and ATAG come up top. We found Online boiler shop to be best of price fully installed too. Very nice guys and happy with the installation. Can’t hear the boiler running it’s that quite. As an engineer myself you can see the build quality is built to last. Would give this boiler 10/10 for quality
