VAILLANT VU 20CS/1-7 ecoTEC exclusive IoniDetect
- wall-mounted condensing boiler 
- output: 2.5 - 20.0 kW 

Modulation ratio 1:10

A wall-mounted condensing boiler for heating on natural gas (propane) with flue gas discharge through a wall, roof, or possibly a shaft or skylight.

New generation condensing technology
The ecoTEC exclusive gas boiler offers condensing technology with many intelligent features in a modern design. The compact wall-mounted appliance is specially designed for use in family houses and represents an investment in the future, whether it's a new building or the modernization of your old heating system.
 
Be prepared for possible fluctuations in gas composition
The heart of the new generation of ecoTEC exclusive boilers is the intelligent IoniDetect combustion control. Since the system automatically detects different types and properties of gas, the combustion system optimizes itself for maximum energy yield. So you don't need to worry if the composition of the supplied gas changes in the future - your boiler will adapt automatically.
 
Awarded the Green iQ label for future technology
The ecoTEC exclusive gas boiler is an investment in ecological heating. It carries our Green iQ label, which represents the highest demands on sustainable technologies and smart connectivity. All Green iQ products can be connected via WLAN, and thanks to compatible technical interfaces, they can also be conveniently controlled on the go using smartphones or tablets.
 
The Green iQ label also means resource-saving production and the use of high-quality recyclable materials from carefully controlled sources.
 
Design for intuitive operation
The attractive design of the new ecoTEC exclusive boiler will catch your eye at first glance. Its clean and clear lines and illuminated black display are a sign of a new era of gas condensing boilers.
 
Not only does it integrate perfectly into your home, operation is also more intuitive than ever before. The improved user interface of the boiler, with touch elements, sliding controls, and full text display, allows you to work with the appliance without fear of making a mistake. All relevant functions are clearly structured and understandable - for quick navigation and setup.
 
Convenient monitoring using touch controls and the app
Intelligent technology doesn't have to be complicated! You can make all heating settings directly on the appliance using the touch controls. Menu navigation is simple and clear, making control even more convenient than before. For simple and intuitive control of the heating system from anywhere, all you need is the sensoNET internet communication module, included in the package, combined with the new sensoCOMFORT system controller. You get easy access to all the main control functions via the free sensoAPP app. Even when you're not at home.
 
Flexible expansion options to increase efficiency and comfort
The ecoTEC exclusive gas boiler brings wide options for expanding the heating system. Combine your boiler with one of the wide range of Vaillant hot water storage tanks. The design of the new uniSTOR wall-mounted storage tanks perfectly matches the new ecoTEC exclusive boiler. And although it takes up only minimal space, it can cover even the highest hot water demands. The sensoCOMFORT system controller controls hot water preparation and up to nine mixed heating circuits. This enables extensions such as heat pumps, solar systems, or ventilation with heat recovery.

Customize your comfort with just a few clicks
Thanks to the new high-resolution display of the sensoCOMFORT and its 3.5-inch screen operating your heating is more convenient than ever before. Six touch buttons, convenient scrolling, and a backlight function simplify control even in dark spaces. Quick navigation and setup are enabled by a clear menu structure and adaptation of the heating system using the installation assistant function. And if you're missing any information, use the help button. With the sensoAPP app on your smartphone or tablet, you can control your heating from anywhere via a wifi connection: set precise temperatures, define time intervals to the minute, and use other special functions, such as absence mode.
 
Upgrade your heating system with renewable sources
From solar systems to ventilation. With the smart sensoCOMFORT controller, you get future-ready system control. The controller is optimized to control all components of the heating system simultaneously, and you can conveniently set up the system according to your needs, e.g. domestic hot water. The sensoCOMFORT controller gives you the ability to manage several heating circuits, and thus more complex heating systems, such as in multi-generational family houses.
 
Coordinated system design for maximum ease of use
Our new generation of gas boilers and controllers (including the sensoCOMFORT controller) have one thing in common: a coordinated menu structure, including the sensoAPP app. So all you need to do is get familiar with one menu structure, and you're familiar with them all, which definitely makes operating your new heating system easier.
 
Designed for your modern home
The system controller should naturally fit into your interior. The modern design is attractive and recognizable, as it resembles modern smart devices. This way, it integrates perfectly into modern living spaces. The same applies to our sensoAPP app. It builds on the previous multiMATIC app, which won the Red Dot Design Award.

Frequently asked questions

  • How exactly do I choose the output of a VAILLANT condensing boiler? The basis is the calculated heat loss of the heated building (most reliably from the project documentation or an energy certificate). If you don't have a project, you can estimate roughly 60-100 W per m² of floor area for a commonly insulated house built after 2000, or 100-150 W/m² for an older, uninsulated house - the exact figure varies depending on the number of floors, ceiling height, number and quality of windows, and building orientation. A boiler oversized for the required output switches on and off more often (so-called cycling), which shortens its lifespan and reduces efficiency; an undersized boiler, on the other hand, cannot sufficiently heat the house on frosty days.
  • Why is a condensing boiler more economical than a classic one? A condensing boiler additionally makes use of the heat hidden in the water vapor produced when burning gas - in a classic boiler this vapor leaves unused through the chimney, while in a condensing boiler it is cooled below the so-called dew point, the vapor condenses, and the released heat is returned to the heating circuit. Thanks to this, condensing boilers achieve an efficiency of approximately 105-110% relative to the calorific value of the gas, compared to the usual 85-92% for classic boilers.
  • What type of flue gas discharge does this boiler need? Most modern condensing boilers are so-called turbo boilers (with a sealed combustion chamber) and require a coaxial (concentric) or separate flue gas discharge and combustion air supply routed through an exterior wall or roof - so they do not need a functional chimney. You can find the exact type and maximum length of the discharge (according to the 60/100 or 80/125 mm diameter) in the technical documentation for the specific model, or consult our customer service.
  • What does the ErP energy class shown for the boiler mean? This is a mandatory efficiency label for heating appliances under the EU ErP (Ecodesign) directive, similar to the energy labels on refrigerators. Condensing boilers commonly achieve class A, or higher in combination with room controls (e.g. A+ when using weather-compensated control and a room thermostat).
  • Can I install and connect this boiler myself? No. Connection to the natural gas supply, the electrical network, and the flue gas discharge is by law exclusively the responsibility of a person with the appropriate qualification (most often an authorized service technician of the given brand or a gas appliance inspection technician). After installation, the boiler must be commissioned by the manufacturer's authorized service, which is usually also a condition for the warranty to be valid.
  • What about service and warranty? Most manufacturers require a regular annual service inspection by an authorized service provider so that the warranty remains valid even after its standard expiry (an extended warranty with regular servicing is common especially for the brands Vaillant, Protherm, and Viessmann). You can find the exact warranty conditions in the warranty card supplied with the boiler.
  • What is included in the delivery of this specific product? The exact package contents (the boiler itself, possibly a domestic hot water cylinder, room controls, and other accessories in the case of a set) are stated in the product name and in its technical parameters above on this page.

Dobry vecer, chcem sa spytat. je mozne zostavu HEWALEX 20 pouzit aj na ploche strechy? Druha otazka, pri zasobnikoch sa pise, ze ma druhu spiralu na ohrev z ineho zdroja. je mozne na tuto spiralu pripojit tepelne cerpadlo (napr. znacka ariston) a zvysit si tym ucinnost v chladnom obdobi? A posledna tretia otazka, pri doplneni tretej - elektrickej spiraly, a moznosti pripojenia tepelneho cerpadla, mozu vlastne tri sposoby ohrevu vody bezat sucasne? Dakujem.
A Avatar of author 13/12/2021 13:30
DObrý deň, 1. solárne panely je možné použiť aj na ploché aj šikmé strechy, vymení sa len držiak. 2.v zásobníku sú dve špirály, hore pripojíte kotol a dole solárne panely. Ariston nuos už nebudete mať kde pripojiť a ani podla mňa to nebude možné vyregulovať, keďže ariston už má svoju nádobu. 3. Áno všetky môže bežať súčasne, ale skôr sa preferuje len solár, elektrika a kotol sú len ako doplnkové kúrenie.
