Outdated Product
Highly efficient double-circuit gas boiler with the condensing principle of heat transfer. Compared to classic double-circuit boilers, it has higher energy efficiency and is able to save gas consumption by 7-8%. It is distinguished by the presence of an additional stage of flue gas cooling, which makes it possible to use the heat of condensation of water vapor formed during the combustion of fuel. It is also equipped with a modulating burner with an extended power control range (from 20 to 100%), which further increases the flexibility and efficiency of using natural gas. High-quality chromium-nickel stainless steel is used as the heat exchanger material. Electronic control of the heating boiler Vaillant ecoTEC plus VU INT 246/5-5 has an informative display and an intuitive interface. It i...s possible to connect an external thermostat-programmer, which is purchased separately. The boiler provides fast heating of the hot water circuit (maximum temperature 65 °C) and is capable of producing up to 11 L/min of heated water (at a temperature difference of 30 °C). Forced flue gas extraction and a low-noise circulation pump make it possible to install the unit directly in a residential area. Equipped with all necessary protective systems, including frost protection. Made in Germany, backed by a proprietary 2-year warranty.
