iC Economiser 35 Plus
iC Economiser 35 Plus kW
Suitable for medium to large homes with more than one bathroom. ATAG iC Economiser Plus combination boiler with hot water flow rates at 16.1 litres per minute @ 35°C temperature rise.
Our iC Economiser Plus has been described as the combi of the future because it contains an industry leading innovation – our patented Economiser.
Some years ago our design engineers realised there was untapped residual heat left in the boiler after hot water had been heated. Rather than release this energy as waste, they engineered the Economiser, an environmentally friendly innovation that recycles the flue gases for a second time, resulting in optimum energy efficiency.
For complete flexibility, pair the ATAG iC Economiser Plus combination boiler with the ATAG ONE Zone controller to achieve a maximum A+ Energy-Related products rating.

How it works
How it works
The ATAG iC Economiser Plus works by capturing waste energy from the flue gases and uses it to pre-heat the mains water to improve hot water production efficiency, saving both heat and money in the process.
