The ATAG i-Series boilers are a prime example of comfort and efficiency. The i Zone boiler is "heat pump ready" and can seamlessly work with the ATAG Energion M heat pump and other heat pumps. The wall-mounted boiler provides comfortable warmth and quickly produces ample hot water. Filling a bath or using the shower with large amounts of water is no problem for the ATAG i-Zone.
Choosing Stainless Steel (RVS)
The stainless steel heat exchanger, the "heart" of the boiler, is the most important and also the most delicate component of the boiler. This heat exchanger is made of stainless steel, which is resistant to corrosion and wear and ensures maximum heat transfer. This not only reduces maintenance frequency but also heating costs. After 15 years, the P-Series is still just as energy-efficient as it was on the first day of purchase.
Energy-Efficient Heating with ATAG One
The ATAG One is a smart thermostat that thinks ahead and plans for the future. Thanks to its so-called start-up optimization, the ATAG One helps you determine when warmth is needed in your home. It works entirely according to your preferences.
ATAG Economizer Flue Gas Cooler
The EC versions (Economizer) differ from the C version due to the Tap Water Technology. An additional heat exchanger (patented Economizer) in the flue gas outlet heats the incoming cold water first during hot water use, before it is heated by the stainless steel heat exchanger to the set temperature. This ensures an exceptionally high tap water efficiency. Additionally, it reduces energy consumption and CO2 emissions.
