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 heating and fast, abundant hot water. Quickly filling a bath or using the shower with a large amount 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 vulnerable component of the boiler. This heat exchanger is made of stainless steel, which is resistant to corrosion and wear, ensuring maximum heat transfer. This not only reduces maintenance frequency but also lowers heating costs. After 15 years, the P-Series is still as 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 anticipates your needs. Thanks to the so-called start-up optimization, ATAG One understands when heat is needed in the house, fully according to your preferences.
