Vaillant ecoTEC plus VU 656/5-5 63.5 kW

Energy-efficient high-power single-circuit gas heating boiler for wall-mounted installation. Equipped with a digital control system with support for the eBus communication bus and the ability to connect a sensoNET Internet gateway for remote control. The key distinguishing feature of this model is the highest efficiency, due to the use of the condensation principle of heat extraction from natural gas combustion products.

Unlike simple boilers, in this apparatus the flue gases are subjected to deeper cooling, which makes it possible to extract from them the latent heat of condensation of water vapor. This solution allows the Vaillant ecoTEC plus VU 656/5-5 single-circuit condensing boiler to save 6-8% of natural gas (compared to classic boilers with equal power). This device uses a closed combustion chamber with forced removal of combustion products.

This design allows you to abandon a separate boiler room and install the boiler directly in residential areas. The high net power of the boiler is sufficient to heat large private households, commercial or domestic premises with a total area of up to 508 m². Equipped with a quiet two-stage circulation pump and automatic air vent. Can work in combination with indirect heating boilers and thermostats with a weekly programming system.
