iS System Boilers from Atag: Europe's Most Energy Efficient System Boilers
Atag iS system boilers have been designed to exceed European energy efficiency legislation, often more stringent than in the UK. Atag boilers are the most energy efficient boilers available in Europe & have the lowest running costs of any combi boiler.
With an Atag iS system boiler you’ll be choosing one of the most energy efficient boilers in Europe. It is not only easy to operate, but also has an in-built ErP pump which controls the heat given out by the boiler to increase energy efficiency and help lower energy bills.
The innovative and patented Economiser Plus feature harnesses residual heat left in the waste flue gases when the boiler is used for hot water, capturing the waste energy and using it to pre-heat the mains water to improve hot water production efficiency, saving both heat and money in the process.
Atag boilers have been awarded the prestigious Best Boiler Award in the Netherlands in multiple years & have the highest score of any boiler manufacturer on Trust Pilot, the independent review site.
Atag iS system boilers are available in the following sizes:
- 15kW suitable for 1 or 2 bedroom properties
- 18kW suitable for 2 to 3 bedroom properties
- 24kW suitable for 3 to 4 bedrooms properties
- 32kW suitable for 4 to 5 bedroom properties
- 40kW suitable for the largest of properties
