The ATAG i-Series gas condensing boilers offer the perfect blend of comfort and efficiency. The i-Zone model is "heat pump ready" and seamlessly integrates with the ATAG Energion M heat pump and other heat pump systems. This wall-mounted boiler ensures cozy warmth and provides ample hot water quickly—ideal for a powerful shower or rapidly filling a bathtub.
The stainless steel heat exchanger is the "heart" of the boiler and its most crucial and delicate component. Stainless steel is highly resistant to corrosion and wear, ensuring maximum heat transfer. This not only reduces maintenance frequency but also lowers heating costs significantly. Even after 15 years, the P-Series remains as energy-efficient as on the first day.
The ATAG One is a smart thermostat that adapts and anticipates. Thanks to its activation optimization feature, ATAG One ensures your home is warm exactly when you need it, tailored to your preferences.
⚠ Note: This is a solo boiler, suitable only for heating. A separate storage tank is required for hot water.
