Increased comfort of domestic hot water
The ecoTEC plus VUI 256 / 5-5 device is an upgrade of the ecoTEC plus VUW 256 / 5-5 device and represents a combination of high-efficiency condensing technology with layered tank technology whose performance is significantly higher compared to classic tanks.
Thanks to the layered tank of 20 liters, which is upgraded to the back of the condensing combined device, the user will have greater comfort of domestic hot water. The tank is only 191 mm deep, so the total is 529 mm, and its installation requires a wall area of only 0.32 m². This is therefore an ideal solution in situations where you are limited by the available installation location.
State-of-the-art “Made in Germany” condensing technology combines reliability and quality with a distinctive Vaillant design and ease of operation. Thanks to the so-called “ELGA” function, the combustion process is constantly monitored and controlled. If the deviation is greater than allowed, the electronics will independently correct the air or gas supply and thus ensure the maximum degree of efficiency.
