Energy-efficient and reliable double-circuit gas boiler with an open combustion chamber, microprocessor control system and support for the built-in eBus communication bus. Designed to service heating and hot water systems in detached houses / cottages, office and commercial premises with a total area of up to 222 m2. The manufacturer is positioned as a product of the middle price category from the atmoTEC plus VUW line of the 2015 model year. The use of an open combustion chamber with flue gas removal due to natural draft requires the placement of the Vaillant atmoTEC plus VUW 280/5-5 boiler in a non-residential (boiler) room with a free supply of fresh air. The device is equipped with a primary copper and stainless secondary heat exchanger, a modulated stainless steel gas burner with wide...power control limits (from 30 to 100%) and a bronze hydraulic group. Significant heating capacity allows you to prepare hot water in an amount of up to 13.4 L / min, which is quite enough to meet the domestic needs of a family of 3-4 people. With eBus support, the boiler is compatible with a wide range of Vaillant programmers and smart controllers.
