ATAG I24S 24 kW System Gas Boiler Review

ATAG Selected Partners offers a standard 10-year warranty for the ATAG I24S boiler. There are also options for an additional 14-year warranty if they are professionally installed. These domestic boilers are well-known for their energy efficiency. They provide years of reliable heating.

Dutch boiler manufacturer ATAG is based in Holland. They claim to have achieved the highest levels of engineering excellence in the world and the best energy efficiency over this period. ATAG makes a range of gas boilers. These include a regular boiler in various sizes, as well as a system boiler and a combi boiler.

ATAG boilers can be made from brass and stainless-steel components. ATAG boilers incorporate the revolutionary iCon heat-exchanger from ATAG, which is unmatched in performance and efficiency.

Why choose the ATAG I24S system boiler?

Choose an ATAG I24S boiler to enjoy energy efficiency. These boilers are easy to use.

Our boilers stand out because of the ErP pumps. The ErP pumps regulate the heat from your boiler and make sure it is as efficient as possible. This will save you money every year.

ATAG iRange boiler conforms to European standards (CE). It’s a closed, condensing, modulating heating boiler. The manufacturer can issue a certificate of conformity.

The boiler’s efficiency is excellent, with low radiation convection and standby losses. The boiler is rated high at >88% SEDBUK 2009. This is due to the fact that it emits noxious chemicals at levels much lower than what is required.
