Vaillant ecoTEC plus VU OE 656/4-5 63.7 kW (0010015695)

High-performance single-circuit heating gas boiler with increased energy efficiency and an open combustion chamber. It features an impressive useful heat output (63.7 kW) and high efficiency, which is achieved through the use of the condensing principle of heat extraction from natural gas combustion products. Flue gases are subjected to deeper cooling, which makes it possible to extract from them the latent heat of condensation of water vapor.

This feature makes it possible to demonstrate high efficiency (109% compared to traditional boilers) and save up to 8% of natural gas with the same heat output. Please note that the installation of the Vaillant ecoTEC plus VU OE 656/4-5 boiler must be carried out in a separate boiler room. And for the safe operation of the device, a number of stringent requirements are put forward for the chimney system, which is designed to provide stable natural draft. The useful power of the device is enough to heat a large private household, cottage, commercial, utility or industrial premises with a total area of up to 510 m2. The boiler is equipped with a quiet circulation pump with progressive frequency regulation, an automatic air vent and a microprocessor control system.
