The ATAG i18S 18kW System Gas Boiler is efficient, reliable and has the potential to save on energy bills. The i18S is ideal for small homes or apartments with little hot water requirements.

The ATAG i18S system boiler has an efficiency rating of 93% and an ErP A-rating for central heating, making this a highly reliable boiler that could potentially help you to save money on your current energy bills.

With an output of 18kW, this system boiler is ideal for smaller homes with up to 10 radiators and a single bathroom. For homes with a higher demand for central heating and hot water, the ATAG i system range is also available as a 24kW, 32kW, and 40kW.

Although the boiler unit itself has been designed to be compact and lightweight; it is important to remember that a system boiler also needs an additional hot water storage cylinder installed alongside the boiler. These are often located in an airing cupboard or a similar size space in your home.

For this reason, system boilers are not ideal for homes with little space. On the plus side, the ATAG i range is also available as a combi boiler for those with limited space in their homes.
