The i40S gas boiler is the most powerful in the ATAG system range, with an efficiency rating of 94% and an ErP A-rating for heat. This high efficiency rating will help you save money on your energy bills. 

The ATAG i40S gas boiler is ideal for medium to larger-sized homes (20+ radiators and up to 2 bathrooms).

If your home has less than 20 radiators, check out the i15Si18Si24S, and i32S system boilers, as their heating outputs are between 15kW and 32kW.

When purchasing a new or replacement system boiler, it is important to remember that you will need space in your home for an additional hot water storage tank. These are usually located in an airing cupboard or similar-sized space in your home. If you do not have that extra space in your home, a combi boiler would be your best bet.
