PRODUCT INFORMATION

iS15 kW

ATAG iS system boilers are available in various outputs from 15kW to 40kW and suitable for most property sizes regardless of the hot water demand.

With an ATAG iS, not only are you selecting one of the most energy efficient boilers in Europe, but you’ll love its easy to operate simplicity too.

System boilers work by heating your home’s hot water and central heating system. The addition of the cylinder means you have access to hot water as and when you need, in the volume required to cope with multiple bathrooms.

What makes our system boilers different though, is the in-built ErP pump. This controls the heat given out by the boiler, ensuring your boiler is as energy efficient as possible, saving you money year-on-year. Customers seeking even more efficiency can combine an iS system boiler with one of our iSteel hot water cylinders.
