ATAG iS System Boiler
System boilers are traditionally fitted with an unvented hot cylinder which provides an increased capacity of hot water. The fact that the pump and controls are contained within the boiler casing counts towards a simple and space saving solution.
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
Homeowners seeking even more efficiency can combine an iS system boiler with one of our iSteel hot water cylinders.
