Vaillant ecoTEC plus VUW 32CS/1-5 27 kW (0010024604)

High-tech German double-circuit gas condensing boiler with a modern digital control system (eBus bus) and a programmer. It is positioned as a product of the upper price category, aimed at demanding users. The main feature of this model is its highest efficiency, due to the use of the condensing principle of heat extraction from natural gas combustion products. Unlike traditional models, in the Vaillant ecoTEC plus VUW 32CS/1-5 condensing boiler, hot flue gases are cooled deeper, which makes it possible to extract from them the latent heat of condensation of water vapor formed directly in the combustion process.

Thanks to this engineering solution, this apparatus is 6-8% more economical than conventional boilers. It has a closed-type combustion chamber and forced exhaust of flue gases, which allows it to be mounted in residential areas. The useful power of such a unit is enough to heat a cottage with an area of 120-216 m². or a city apartment of similar size. It is equipped with a modulating burner (from 12 to 100%), a low-noise circulation pump, a large expansion tank and an automatic air vent.
